As a 60 plus English bike rider I like the sound of the Sparrows in the back ground,don't hear that commonly where I live now,the sound is something from my childhood.
@@MindfulMotorcyclist Listen to Clive!!! I'm 53 and my knees are toast as a consequence of kneeling on hard ground when I was younger. For the sake of a pair of knee pads or a cushion, don't end up like me. Not being able to kneel and having no strength in your knees really inhibits so many things that you never thought about.
I do wonder about decatting bikes. Two reasons, first I rebuilt an 83 Yamaha XS400 over lockdown, it came with a cheap stubby exhaust, got it running but when I rode alsways got off the bike to the smell of burnt oil. Bought an exhaust of eBay from a triumph scrambler, it had a cat in the silencer. Suddenly no exhaust smell and sound was still great. Also when following a bike with a decat I can always tell due to having to breathe all the unburnt waste gases. So I will be considering other road users and pedestrians and not fitting a decat to my current bike. If I want more sound will remove the baffling in the silencer. Hope people with think a little on this viewpoint Thanks for reading
Thanks for your comment. All points of view are welcome. Many riders of the GS have chosen to stick with the standard cat set up, I'm sure I'm actually in the minority. Thanks, Sean
so the oil leaking from your bike is not being burnt of by a different exhaust system ! the only time i smell fumes from any vehicle is really older ones that have an over rich fuel mixture
Great job improvising to get the pipe back into shape! From the views, I see there's a lot of interest in aftermarket parts on the BSA, which is very cool! I saw an article on Cycle World this week about a Benda BD250. It's a little 250 V-Twin bobber that I think looks very similar to the Royal Enfield KX Concept bike from back in 2018.
Hi Mark, the views have gone a little bit crazy with this one. Mainly positive comments, a couple of idiots but that is the downside, when we do a video that does well people outside the core audience come in. With respect to the Benda I believe that is a brand sharing with Keeway which is a bike that I rode on the channel last year. It was called Keeway V cruise but the headlight said Benda... it was a really fun little video twin...
Nice job Sean don't think I'm up to fitting it with my old back and knees but i do really like the sound. 5 kilos with my weight doesn't make a jot of difference but the sound and the looks are what interests me, excellent review.
Thank you Ian for the comment. The sound was a real surprise. I thought the baffle would keep it somewhat muted. I'm still running the standard silencer after all...
I have owned a number of 106d. They truly are fabulous cars and really are as frugal as you say. A 'friend' of mine used to run his on red diesel. Stupidly cheap lol. Nowadays they are just beginning to become collectible, and as such are going up in price...
The series one was particularly special, small and light yet particularly fuel efficient. I had one as my second car, first being a 205 1.1 petrol 4 speed! I also discovered later that the 307 2.0hdi is a very capable load carrier, still good on diesel and still in the cheap phase... ish 😁
Thanks Nigel, I was going for weight saving, looks and perhaps a bit better longevity for the engine. I've got in addition a much improved noise and I think a smidge of extra performance. Either that or the engine has fully loosened up at 1200 miles. Very similar to the RE Meteor in that regard! For under £200 is a cracking upgrade! 👌
The colour of your BSA is georgeous and the exhaust mod looks perfect. The sound didn't convince me. OEM it's a quiet annoying rattling noise, after the upgrade it just got louder. Not unbearably loud, but still annoyingly clattering. I think the whole exhaust system needs to have more volume to create a pleasant sound.
Thank you, I really like this colour and it's the cheapest too. Sometimes you're just lucky 😀. The engine isn't a long stroke so doesn't thump like and old BSA, I've got used to that now and pretty happy. Thanks for the comment.
@@MindfulMotorcyclist The same with my Suzuki DR 800. Short stroke and no place for a propper exhaust adequat for a displacement of 800 ccm in one cylinder.
Take the silencer off and look down the end nearest where the cat was (where your new downpipe joins) you will see another very restricted baffle plate....you can drill this out or knock it out with a long bar and hammer....Will really sound good
A good worthwhile mod, it does sound much better though we didn't hear it as you were riding it, and looks much better without the heatshield. After watching your video l will definitely be adding a couple of chunky logs to my toolkit though it might be a tight squeeze to get them into the little plastic tool bag lmao. Re the R&G crash bung you could easily reshape it to get past the downpipe they are only plastic as l remember, it would be a shame to scrape the new one too!
Hi Munter, yes this is true, I do have a review video coming up with the sound track in full. I thought about also bending the metal back away from the exhaust. The polyurethane bobbin could be reshaped too, although if I shaved 40% of the material away it might just rip off in an accident. My current plan is a 30mm spacer to bring the bobbin out past the downpipe. Logs 😂😂😂, people might hate on this but stuck on the side of the road it worked and got me going with the new exhaust. Thanks for the comment.
Nice job! Regarding crash protection, back in the day, my dad had a simple horizontal chrome bar on his bike in a similar position to your R&G bungs. I notice that Royal Enfield produce that type of guard (check out part no. 1990604 for pictures) and I wonder if you could fit something similar, maybe over the stub left by your crash bung.
Thanks Luddite, I was thinking of a steel spacer about 30mm just to bring the mount out past the header pipe then a longer bolt and refit the standard polyurethane bobbin back on. Wouldn't be as solid as factory but still not too bad. Will have to wait until back in the UK to have one made up. Cheers, Sean
Is that corrosion on the back of your exhaust??? Tip for you...get an old section of carpet to work on....can put stuff down with out marking it. Make sure to keep the old cat and pipe work....case its needed in future. Landrover haven by the looks of it...I have a 50 year old S3 88" biught it brand new aged 23.....always loved them from my childhood. Still going great to this day....replaced the old gutless 2.25d with a 200di out of a Mk1 Discovery.....WOW.....the difference...40mph and goes great.
Hi Nick, thanks for the comment. It was probably the anti corrosion spray that had baked on there. It came off with some gentle abrasion. The silencer is stainless so I would hope no rust. Cheers. Sean
Hi Dan, thanks for the comment. I was only really fitting it to lighten the bike and remove unnecessary weight. The sound was an unexpected but very welcome surprise! Thanks.
Even with an exhaust change, its not my idea of music! I will stick to my 500 enfield bullet, without a cat, and an ECU.. i can play about with numerous aftermarket exhausts, without upsetting anything, and alwsys keep that lovely deep thump, of a proper longstroke engine.
looks great sounds great without being to loud plus weight saving and the cat holds a lot of heat so the crankcase area should be cooler you might even save fuel ?
@@MindfulMotorcyclist next time put a clamp on draw it in slowly to fit down pipe on, WOOD be more accurate! ( get the joke )🙂 you done well though with the log ! ride safely. 🇬🇧🇪🇦
Well I've got two of these silencers already, my current one and a non scratched - not bust up one in the shed in the UK. I'll probably fit that one as a first point of call! Cheers. Sean
Someone had to say it. The fact that it idles so high negates any effort in attempting to change the bike into an old fashioned thumper. To my ears it doesn't sound any different. Until something is done to the high idling the money would be better spent on petrol.
Got the decat too and the sound improvement is amazing. My only issue has been the extra heat of the exhaust. ¿Have you find any issue about the decat? Ill be watching your videos to see the long term use of it, if something happens on mine ill let you know!
I've not found any issue with extra heat, I've not been in as hot weather as you have in Valencia. My exhaust has discoloured quite a lot at the top but I don't mind that. Thanks for supporting the channel by the way and glad you have a Goldstar!
Thanks Mark, I was considering a 30mm spacer on the 'stud' and a longer bolt just to bring the polyurethane bobbin out past the header. That or a machine shop to move the 'stud' away from the exhaust. Something to figure out when back in the UK and with a full set of tools...
Did the de-cat on my 2020 Triumph T100....transformed the bike.....more mpg....more grunt....sounds great....not to noisy....low RPM so much smoother.....oh yes.....around 3kg pluis lighter. 12min adaption after the cooling fan kicks in on my Triumph. You didn't say....how does it run now on the road..... Pity the BSA idles so fast.....the old Goldies used to have a nice slow idle with the great thump thump sound. Lots of other benefits as well.
That's right Nick, I was going for cleaner lines down the bike and a weight saving, I also got as a bonus a much improved sound and a smidge more performance out on the road, hard to quantify exactly as my bike is approaching fully run in at 1200 miles and the engine feels better and better. I expect the engine will run better over its life because it can breathe easier owing to the unobstructed flow. All in all an exceptionally good value mod for sub £200. Feels great in the hand to so well done Hitchcocks!
I like the simple Ness of this short film…. So much reminded me of the maintenance back in the day when motorbikes were generally a young young man’s. Every day means of transport and had to do things on the hoof sometimes….. at first I thought oh how much difference would that make but what a considerable difference both on look and sound and I liked it a lot. The only thing that I’m trying to get my head around, how might that affect the annual emissions test with the cat removed? Thanks for your post great .
Thanks John appreciate the comment. I don't believe euro5 requires an emissions test over the lifetime of the vehicle. I looked up on the government website and read this: The only vehicles that do not have an emissions test as part of the MOT are: vehicles with fewer than 4 wheels vehicles with 2-stroke engines hybrid vehicles quadricycles hydrogen fuel cell vehicles electric vehicl
I personally prefer the tec option, but this does sound impressive. I hope soon somebody releases an air filter like the ones available for the royal Enfield models.
Thanks Chris for the comment. I think the TEC would actually save more weight because I suspect the BSA end silencer is quite heavy. I did look long and hard at the TEC, was a close decision. Cheers.
Get yourself a 3/8 and 1/4 drive socket set. You will be surprised at how much easier maintenance will become. Also you stand less chance of stripping threads due to over torquing because ofthe size of the 1/2 inch socket drive.
I do actually have both these, I just have a longer ext bar for the 1/2 inch. I am very wary of stripping threads, can you imagine the pain that would be. By the way what would you say is the correct torque for head bolts. Probably less than 20nm at a guess??
@@MindfulMotorcyclist good morning to you from another beautiful day here in Western Australia. I was intrigued by your you tube post as I really like the look of the new BSA. My first big bike at exactly 16 yrs of age was a 1958 BSA B31 alternator model which cost me £15 from a near neighbour. A fabulous intro to motorcycling and so reminiscent is your new version. Where are you now WOL 791? There is a pdf link to a manual on the new bsa 650 owners Facebook page which may help you with regard to torque figures for your bike. My first BSA led to a long history of motorcycling and race preparation in my life. I spannered for myself, Tim Lee, Tony Head and the great Rod Scivyer over a 25 year period and also for Rob Lidgate with his classic and vintage racing motorcycles. It’s too dangerous here in WA to have a motorcycle on the road as driving standards are appalling and there is only a small cadre of road racers and circuits, the best being down at Collie in WA. Regards and good fortune on your motorcycling journey. Mike Wilkins.
Nice addition Sean looks well sounds better will you now replace the silencer with a new standard one or just leave it since it works fine just having that little scrape or could that be polished out since it's stainless if there is enough thickness of metal and the scratches aren't to deep . 👌👍
Great question Crumbly, I do have a spare silencer in the shed that was kindly given to me post accident, I didn't fit it before we went away. I actually quite like the 'battle scars' and the skill and practice of repairing damaged or broken things. I've brought with me sandpaper of various grades and autosol as you say we could get that exhaust close to factory with time and effort. The main reason I would plan to change to the new item is the fit will be perfect, I don't want to have to wrestle with the thing if I am ever involved in replacing the exhaust again. It doesn't exactly line up perfectly and was a struggle to get in place but then I suppose what exhaust does line up perfectly 😃
Very smart there! I have just finished editing a video with that exact solution. I used an aluminium spacer 45mm to push out the polyurethane bung past the pipe. Thanks 😊
Hi Sean, Great to see you getting to the spanners on the BSA. Not a bike I've got to working on yet so interesting to see how these are assembled. One curiosity, I noticed something at 6:27 when removing the silencer. It seems the mount that was attached to the back of the pillion footpeg was quite deformed. Given the low mileage I'm trying to determine is this early signs of wear and tear due to the weight? Accident Damage? or Heat damage and the rubber isn't spec'd correctly? Is this something you noticed?
Hi TheWurks! Let me start by saying I'm a mere tinkerer with bikes and not a man of your considerable talent when it comes to engines, I've enjoyed your Freddies Bonneville series. The silencer took a fair blow when I crashed it back in November, the metal tab welded onto the silencer at the rear that mounts to the rear passenger rhs footage was bent out of shape meaning the silencer sits closer to the bike than it should do also making the bolt at the front mounting point difficult to get into position. I've roughly bent the rear tab back, on the side of the road with no tools and so I could just about get it lined up correctly. So to answer in short it's accident damage really, the rubbers I will replace when I'm back in the UK. Thanks for the comment. Sean
Hi Paul, could be a leak from where the header pipe meets the silencer on account of mine being accident damaged. At the cyclinder I used a new gasket and it mated up very well so would not suspect there. Thanks!
Lot nicer sound and looks better , that scratch on silencer would polish out , I got set of brushed stainless Vance Hines for my Thruxton 1200s they were cheap due to being scraped , bit of work with wet n dry then polish with buffing wheel They came up like chrome much more classic looking than the original dull brushed finish , think it would really suit your Goldstar being polished rather than brushed and get rid of scrape
Hahaha I do have one I think it's 10-50nm, I just took care not to strip the aluminium head threads. Christmas list would be a 30-100nm wrench... if you talk to Suzie 😂😂. Hope you're doing well!
Just wondering, what is the legality of a decat? catalytic converters a obviously fitted for an environmental reason, would a bike get through an MOT test with the new sertup? I used to have a Triumph Thunderbird ( before the days of catalytic converters, though the model for export to California had them) with straight through silencers, They were genuine Triumph parts, but in their wisdom?? Triumph had stamped on them "not legal for road use" ( or similar) Changed them back for the original ones for the MOT. The new setup sounds lovely!
Hi Pete, thanks for the question. The MOT emission check is exempt as per a reliable source of gov.uk 'The only vehicles that do not have an emissions test as part of the MOT are: vehicles with fewer than 4 wheels vehicles with 2-stroke engines hybrid vehicles quadricycles hydrogen fuel cell vehicles electric vehicles' You could get caught out in a 'clean air zone' but I live in on the edge of a small city. My dad has a Tbird, loves it and I hope to feature it on the channel soon. Thanks!
Great job Sean you need a kneeling pad really, it does sound better and looks better, I like the caveman bashing with the logs 😂😂😂 I shan’t be changing mine I have other machines that give me the noise I need 😊😊 Have a great Easter Phil
Hi, Sean. Fine video. I'm not sure if your bike is gonna be street legal in Spain, but I doubt anyone notices it. I had a Royal Enfield Classic 500 with a BSA pipe and it even passed the ITV test (the equivalent here to the MOT) without qualms. I'm waiting eagerly for my BSA in a couple of weeks and this is a modification I'm considering, so you vid was really helpful. You say that you've watched the TECs videos on their exhaust system. If memory serves me well, I think they say that the pipe head is basically useless and in fact rises the temperature so much that it causes that blueish tinge in the pipe. What do you think about it? Have you noticed it in your modification?
Thank you very much for the comment. Both my original downpipe going into the cat and this decat pipe both blued very quickly. I suspect that due to Euro5 these bikes run very lean and very hot 🔥. Perhaps if you removed the baffle it would permit more gas flow and reduce heat. Thanks. Sean
@@MindfulMotorcyclist no, they can't run lean with Euro 5. They have to run at stoichometric mix, lambda = 1 which means they run with exactly the amount of fuel that is required to burn all the oxygen. At max power, most manufacturers anyway cheat a bit and inject more fuel to reduce the combustion temperature. But the engines will for sure not run lean.
Thanks MT appreciate the comment. Yes the rad is certainly something you get used to. Hopefully in the future they reduce the size down. Believe it or not I am OK with it now, a necessary evil to make the required power output in this Euro5 regulation environment. Cheers.
@muckytrails323 - They can’t make it air cooled because of fuel injection/emission regs. You would have to go back to a carburettor. Mind you, if you’ve already ditched the cat, why not?
Funny you say that, there was an April fools post with a carb conversion kit for the 2023 BSA Goldstar... I'm sure a few would have wanted it to be true.
l know this doesn't apply at the movement but what happens when its time for ITV... will you change back to OEM for test of like l did 'once' take a chance, that turned out to be a bad call since the bike failed immediately ...
The space was originally occupied by the cat, if I had to guess it was because they wanted to give the impression of a straight through pipe as per Goldies of old and so went to lengths to hide the cat under there...
If removing the catalytic converter is a "good thing" for the reasons you state, then why didn't BSA simply build it that way? It did cost you some money and effort to modify.
Perhaps the "CO2 = harmful emissions" extremists have desensitized us to the real good that is done by catalysts in removing carbon monoxide and unburned hydrocarbons.
MOTs are not required in the UK until the vehicle is 3 years old. Vehicles with less than 4 wheels are exempt from emissions testing during an MOT test.
Thanks Wrighty for the comment, I have those tools at home in the UK, seemed a waste to buy again here.... and yes the wood was taken from the log burner pile 😂
Does that mean your bike is no longer ULEZ compliant? Of course modern bikes with catalytic converters only need decorative end cans as the cats' do most of the silencing duties. Removing the cat will mean a much louder exhaust. The gas seal joint between the header and and the end can relies on the two parts being a close fit. Being bashed out of round when crashed and then bashed again with cave man tools will mean the exhaust will leak. I fear that any "green" credentials you may aspire to have been flushed down the toilet with this 'modification'. As far as testing the sound at tickover revs - that is no test at all. You might find that at mid throttle revs it'll give you a headache after an hour of so.
Hi Dave, I'm not in ULEZ and I'll never live in one. Regarding the gas seal yes my current exhaust silencer is never going to be factory fresh again, its scuffed and bashed up and as you say ive only knocked it back into shape enough to fit.. I do have a spare silencer in the shed in the UK so I might swap that back on in the summer, at that point it might be a gas tight and better fit. Thanks.
I imagine BSA did not choose a 1800cc air cooled V twin for the following reasons: A) it would be price prohibitive, for the desired market segment B) they wanted a single not a twin for heritage reasons C) power output would necessitate other changes to drive chain, chassis and brakes D) The weight of the bike would increase E) unacceptable delay to develop from scratch a v twin aircooled F) Poor allocation of R&D resources I could go on... basically the same reason you don't see an inline 4 supercharged motor putting out 200hp in a Royal Enfield Bullet 350...
And the award for least aware commenter goes to... 😂. We're on an Spanish island with limited tools did you not see the reg plates! The silencer was scratched from an accident in November which I spoke about multiple times. You've looked but seen nothing.
Bike sounds like it can breath now. That's usually what I delete first on my bikes is the heavy, heat sink, bread box cats. Bikes run so much better without that Environment police garbage.
Removing the catalytic converter means removing the exhaust cleaning device, meaning becoming a contributor to smog and poluted air. Plus facing problems at the regular vehicle check, and possible police controls. Doesn't seem very mindful to me... if you want your new motorbike to produce pollution, why not save money and buy an old bike right away?
A lot of work went into designing and building the new BSA, a challenge to get right given the history of the marque. Many people are happy enjoying these bikes which dont cost a lot and ride great. You, on the other hand, are up watching RUclips at 2 am trying to upset those people with a rude comment. Says more about you than the BSA.
@@trevortrevortsr2 nope, it's easy to fit an exhaust for the purposes of an MOT. I do that with mine, takes half an hour. Meanwhile I'm going for a drive in my diesel pickup, one day I'll change the injectors because it's a bit smoky 🤣🤣🤣🤣
Indeed. Man above probably doesn't realise kids are getting poisoned by extracting cobalt ore with their bare hands in Congo but he's guilt free driving a zero emissions vehicle. Life of vehicle emissions it's a cheap secondhand diesel everytime...

Well I've got two of these silencers already, my current one and a non scratched - not bust up one in the shed in the UK. I'll probably fit that one as a first point of call! Cheers. Sean
An even more real Gold Star...not to be confused with a massively overweight Mahindra with borrowed BSA tank plates.
The beauty of the old BSA's: the lumpy idle...with FI, they set idle between 1100-1300, and...not as good...
I do agree here, one thing I will say is its probably due to emissions regs but I would prefer it to idle lower...
Someone had to say it. The fact that it idles so high negates any effort in attempting to change the bike into an old fashioned thumper. To my ears it doesn't sound any different.
Until something is done to the high idling the money would be better spent on petrol.
nice they are making bsas again but the original ones made in the uk had awesome sound
Got the decat too and the sound improvement is amazing. My only issue has been the extra heat of the exhaust. ¿Have you find any issue about the decat? Ill be watching your videos to see the long term use of it, if something happens on mine ill let you know!
I've not found any issue with extra heat, I've not been in as hot weather as you have in Valencia. My exhaust has discoloured quite a lot at the top but I don't mind that. Thanks for supporting the channel by the way and glad you have a Goldstar!
Good job Sean, shame about the crash protection, could an edge be removed maybe so it still fits 👍
Thanks Mark, I was considering a 30mm spacer on the 'stud' and a longer bolt just to bring the polyurethane bobbin out past the header. That or a machine shop to move the 'stud' away from the exhaust. Something to figure out when back in the UK and with a full set of tools...
Did the de-cat on my 2020 Triumph T100....transformed the bike.....more mpg....more grunt....sounds great....not to noisy....low RPM so much smoother.....oh yes.....around 3kg pluis lighter.
12min adaption after the cooling fan kicks in on my Triumph.
You didn't say....how does it run now on the road.....
Pity the BSA idles so fast.....the old Goldies used to have a nice slow idle with the great thump thump sound.
Lots of other benefits as well.
That's right Nick, I was going for cleaner lines down the bike and a weight saving, I also got as a bonus a much improved sound and a smidge more performance out on the road, hard to quantify exactly as my bike is approaching fully run in at 1200 miles and the engine feels better and better. I expect the engine will run better over its life because it can breathe easier owing to the unobstructed flow. All in all an exceptionally good value mod for sub £200. Feels great in the hand to so well done Hitchcocks!
Would be interesting to hear how much more mpg?
@@GGT2501 I gained about 3mpg on my 2020 Triumph T100 Bonnie....speeds around 50-60mph.....getting 73mpg
I like the simple Ness of this short film…. So much reminded me of the maintenance back in the day when motorbikes were generally a young young man’s. Every day means of transport and had to do things on the hoof sometimes….. at first I thought oh how much difference would that make but what a considerable difference both on look and sound and I liked it a lot.
The only thing that I’m trying to get my head around, how might that affect the annual emissions test with the cat removed?
Thanks for your post great .
Thanks John appreciate the comment. I don't believe euro5 requires an emissions test over the lifetime of the vehicle. I looked up on the government website and read this: The only vehicles that do not have an emissions test as part of the MOT are:
vehicles with fewer than 4 wheels
vehicles with 2-stroke engines
hybrid vehicles
quadricycles
hydrogen fuel cell vehicles
electric vehicl
So I guess only a roadside test could potentially get you in trouble...
I like the full chrome version. Who makes that please?
Stainless just isn't right.
Moore Speed Racing make a chrome plated or polished stainless item, the latter is more expensive by a touch. Thanks 👍
@joetocchio9666... Agreed!
Watched your last vlog about what is a proper biker you are 100 per cent biker all about a school day
Thank you Howard 👍
I personally prefer the tec option, but this does sound impressive. I hope soon somebody releases an air filter like the ones available for the royal Enfield models.
Thanks Chris for the comment. I think the TEC would actually save more weight because I suspect the BSA end silencer is quite heavy. I did look long and hard at the TEC, was a close decision. Cheers.
Get yourself a 3/8 and 1/4 drive socket set. You will be surprised at how much easier maintenance will become. Also you stand less chance of stripping threads due to over torquing because ofthe size of the 1/2 inch socket drive.
I do actually have both these, I just have a longer ext bar for the 1/2 inch. I am very wary of stripping threads, can you imagine the pain that would be. By the way what would you say is the correct torque for head bolts. Probably less than 20nm at a guess??
@@MindfulMotorcyclist good morning to you from another beautiful day here in Western Australia. I was intrigued by your you tube post as I really like the look of the new BSA. My first big bike at exactly 16 yrs of age was a 1958 BSA B31 alternator model which cost me £15 from a near neighbour. A fabulous intro to motorcycling and so reminiscent is your new version. Where are you now WOL 791?
There is a pdf link to a manual on the new bsa 650 owners Facebook page which may help you with regard to torque figures for your bike.
My first BSA led to a long history of motorcycling and race preparation in my life. I spannered for myself, Tim Lee, Tony Head and the great Rod Scivyer over a 25 year period and also for Rob Lidgate with his classic and vintage racing motorcycles. It’s too dangerous here in WA to have a motorcycle on the road as driving standards are appalling and there is only a small cadre of road racers and circuits, the best being down at Collie in WA. Regards and good fortune on your motorcycling journey. Mike Wilkins.
Good of you to pay homage to tradition by parking the bike over an oil stain😂
Good comment!😂 I thought about that also.
A happy accident there, yes good comment 👍 😀
Waste of words and not even funny.
Nice addition Sean looks well sounds better will you now replace the silencer with a new standard one or just leave it since it works fine just having that little scrape or could that be polished out since it's stainless if there is enough thickness of metal and the scratches aren't to deep . 👌👍
Great question Crumbly, I do have a spare silencer in the shed that was kindly given to me post accident, I didn't fit it before we went away. I actually quite like the 'battle scars' and the skill and practice of repairing damaged or broken things. I've brought with me sandpaper of various grades and autosol as you say we could get that exhaust close to factory with time and effort. The main reason I would plan to change to the new item is the fit will be perfect, I don't want to have to wrestle with the thing if I am ever involved in replacing the exhaust again. It doesn't exactly line up perfectly and was a struggle to get in place but then I suppose what exhaust does line up perfectly 😃
You need a longer bolt and a piece of tubing to extend the crash protector.
Very smart there! I have just finished editing a video with that exact solution. I used an aluminium spacer 45mm to push out the polyurethane bung past the pipe. Thanks 😊
Do you need a fuel x light if you remove the cat? Great chanel😊
Thanks Peter and no I haven't fitted Fuel X
Hi Sean, Great to see you getting to the spanners on the BSA. Not a bike I've got to working on yet so interesting to see how these are assembled. One curiosity, I noticed something at 6:27 when removing the silencer. It seems the mount that was attached to the back of the pillion footpeg was quite deformed. Given the low mileage I'm trying to determine is this early signs of wear and tear due to the weight? Accident Damage? or Heat damage and the rubber isn't spec'd correctly?
Is this something you noticed?
Hi TheWurks! Let me start by saying I'm a mere tinkerer with bikes and not a man of your considerable talent when it comes to engines, I've enjoyed your Freddies Bonneville series. The silencer took a fair blow when I crashed it back in November, the metal tab welded onto the silencer at the rear that mounts to the rear passenger rhs footage was bent out of shape meaning the silencer sits closer to the bike than it should do also making the bolt at the front mounting point difficult to get into position. I've roughly bent the rear tab back, on the side of the road with no tools and so I could just about get it lined up correctly. So to answer in short it's accident damage really, the rubbers I will replace when I'm back in the UK. Thanks for the comment. Sean
What does the pipe do to emissions?
I’ve no experience of this bike, but my first impression when you fired it up was you’ve an exhaust leak…
Hi Paul, could be a leak from where the header pipe meets the silencer on account of mine being accident damaged. At the cyclinder I used a new gasket and it mated up very well so would not suspect there. Thanks!
Can’t fault Hitchcocks. Postage to Australia is expensive, but the company is professional and their gear always top-notch.
I would buy from them again, great company 😀👍
@@MindfulMotorcyclist enjoy the video. Thanks!
Lot nicer sound and looks better , that scratch on silencer would polish out , I got set of brushed stainless Vance Hines for my Thruxton 1200s they were cheap due to being scraped , bit of work with wet n dry then polish with buffing wheel
They came up like chrome much more classic looking than the original dull brushed finish , think it would really suit your Goldstar being polished rather than brushed and get rid of scrape
Great idea, ive sanded out a lot of the damage to the silencer... could go further as you say.
Great work and very interesting!
Thank you very much that's incredibly appreciated 👏.
Im going to get you a torque wrench for your birthday, loved watching someone else working 😂 Sounds great
Hahaha I do have one I think it's 10-50nm, I just took care not to strip the aluminium head threads. Christmas list would be a 30-100nm wrench... if you talk to Suzie 😂😂. Hope you're doing well!
I bet you don’t get him one.
Yes Brian you said it now! 😃😆🫢
Great new sound not that much loader just a deeper note.
Thanks Andy, I'm used to the sound now if that make's sense. It's nice without being uncomfortable or antisocial. Good job Hitchcocks...
had one of those 106s brilliant except it dissolved in uk winter salt
I just made a post about them, especially after seeing this comment Graham 😁
Just wondering, what is the legality of a decat? catalytic converters a obviously fitted for an environmental reason, would a bike get through an MOT test with the new sertup?
I used to have a Triumph Thunderbird ( before the days of catalytic converters, though the model for export to California had them) with straight through silencers, They were genuine Triumph parts, but in their wisdom?? Triumph had stamped on them "not legal for road use" ( or similar) Changed them back for the original ones for the MOT. The new setup sounds lovely!
Hi Pete, thanks for the question. The MOT emission check is exempt as per a reliable source of gov.uk
'The only vehicles that do not have an emissions test as part of the MOT are:
vehicles with fewer than 4 wheels
vehicles with 2-stroke engines
hybrid vehicles
quadricycles
hydrogen fuel cell vehicles
electric vehicles'
You could get caught out in a 'clean air zone' but I live in on the edge of a small city.
My dad has a Tbird, loves it and I hope to feature it on the channel soon. Thanks!
Great job Sean you need a kneeling pad really, it does sound better and looks better, I like the caveman bashing with the logs 😂😂😂
I shan’t be changing mine I have other machines that give me the noise I need 😊😊
Have a great Easter
Phil
Thanks Phil. You have an original GS don't you? No need to take out the Cat in that 🤣.
Most excellent video.
Thank you Paul, much appreciated 👏
If you were doing a similar job on the triumph you’d have to unbolt the frame sub assembly. Another reason I bought my Harley
On a Triumph you have to unbolt the subframe to swap an exhaust downpipe??
Does the ecu really mange to recalibrate on its own, and the idlling speed sounded slower ?
Mine has, 6 months later and bike is riding fine...
Hi, Sean. Fine video. I'm not sure if your bike is gonna be street legal in Spain, but I doubt anyone notices it. I had a Royal Enfield Classic 500 with a BSA pipe and it even passed the ITV test (the equivalent here to the MOT) without qualms. I'm waiting eagerly for my BSA in a couple of weeks and this is a modification I'm considering, so you vid was really helpful.
You say that you've watched the TECs videos on their exhaust system. If memory serves me well, I think they say that the pipe head is basically useless and in fact rises the temperature so much that it causes that blueish tinge in the pipe. What do you think about it? Have you noticed it in your modification?
Thank you very much for the comment. Both my original downpipe going into the cat and this decat pipe both blued very quickly. I suspect that due to Euro5 these bikes run very lean and very hot 🔥. Perhaps if you removed the baffle it would permit more gas flow and reduce heat. Thanks. Sean
@@MindfulMotorcyclist no, they can't run lean with Euro 5. They have to run at stoichometric mix, lambda = 1 which means they run with exactly the amount of fuel that is required to burn all the oxygen. At max power, most manufacturers anyway cheat a bit and inject more fuel to reduce the combustion temperature. But the engines will for sure not run lean.
Only thing I don’t like about this bike is the radiator wish they made it air cooled like original
Thanks for your video 👍
Thanks MT appreciate the comment. Yes the rad is certainly something you get used to. Hopefully in the future they reduce the size down. Believe it or not I am OK with it now, a necessary evil to make the required power output in this Euro5 regulation environment. Cheers.
@@MindfulMotorcyclist enjoyed your vid still want to get one tho ❤️
@muckytrails323 - They can’t make it air cooled because of fuel injection/emission regs. You would have to go back to a carburettor. Mind you, if you’ve already ditched the cat, why not?
Funny you say that, there was an April fools post with a carb conversion kit for the 2023 BSA Goldstar... I'm sure a few would have wanted it to be true.
I'd like to hear it with a proper original Gold Star silencer.
I expect it would be very loud. The silencer I'm using has baffles.
l know this doesn't apply at the movement but what happens when its time for ITV... will you change back to OEM for test of like l did 'once' take a chance, that turned out to be a bad call since the bike failed immediately ...
Hi Brian, if I was in Spain I would change bike back with cat prior to the test I expect. Thanks.
That begs the question, why is the engine so high in the frame?
The space was originally occupied by the cat, if I had to guess it was because they wanted to give the impression of a straight through pipe as per Goldies of old and so went to lengths to hide the cat under there...
I have a big thumper most mornings....
Not if you have your cat removed 😂
If removing the catalytic converter is a "good thing" for the reasons you state, then why didn't BSA simply build it that way? It did cost you some money and effort to modify.
Thanks Overlander 👍
Perhaps the "CO2 = harmful emissions" extremists have desensitized us to the real good that is done by catalysts in removing carbon monoxide and unburned hydrocarbons.
No emissions test in UK
Very good !
Thanks Nick!
Should you have fitted the down pipe first ?
I should have quite right, I mention this at the end of the video. Easier to line up at the cylinder and work back. Cheers
Isn’t it illegal to use or sell or MOT a motorcycle without a catalytic converter?
No and there is no test for it, that said euro 6+ might introduce lifetime emissions tests which bikes would then fail.
Does it rain mud instead of water where you live?
In Majorca, yes, i don't live there tho
I’m only half way through through and laughing my head off, learning many new words, “go on you MF” LMHO!
Lol this is actually meant to be a family friendly channel, that one slipped through the edit ☺️☺️
you have a brand new bike and you remove the cat ? am I right ?? do you need MOT or anything ? are you even legal any more ?
MOTs are not required in the UK until the vehicle is 3 years old. Vehicles with less than 4 wheels are exempt from emissions testing during an MOT test.
does decat will effect pollution test
We dont have pollution test but if you did it probably would, thanks 😊
Sometimes the baffles have been known to ' fall ' out from motorcycle silencers . if you follow me ?
I follow you 😆. This is now loud enough with the baffle in! Haha
Yes, my number plate would fall off too occasionally. Ah well, never mind. These things happen.
Dont worry, some faceless bureaucrats in Brussels will be working hard to ban these modifications.
Exactly, we will all be riding electric bikes in 10 years so I would like to enjoy my simple machine now while I can 😃
Buy a copper hide mallet and some other tools...Lumps of wood are for the log burner...
Thanks Wrighty for the comment, I have those tools at home in the UK, seemed a waste to buy again here.... and yes the wood was taken from the log burner pile 😂
Is the tick over that high?
Probably, its an oversquare water cooled BMW rotax engine which is on an early ECU map... theres a lot there contributing to the tickover! Cheers
@@MindfulMotorcyclist Thanks, used to have a BSA Starfire back in the day, and that thumped at tick over...
What happens at mot testing time will it still pass ?
Why wouldn't it pass?
Euro 5 doesn't stipulate emissions check over the life time of the vehicle.
watch = old n goldie ,, for the speedo clocks risers ;;
I was thinking about the speed risers but they are £160, I think you've got to really want them for that price. Thanks Simon.
Does that mean your bike is no longer ULEZ compliant? Of course modern bikes with catalytic converters only need decorative end cans as the cats' do most of the silencing duties. Removing the cat will mean a much louder exhaust. The gas seal joint between the header and and the end can relies on the two parts being a close fit. Being bashed out of round when crashed and then bashed again with cave man tools will mean the exhaust will leak. I fear that any "green" credentials you may aspire to have been flushed down the toilet with this 'modification'. As far as testing the sound at tickover revs - that is no test at all. You might find that at mid throttle revs it'll give you a headache after an hour of so.
Hi Dave, I'm not in ULEZ and I'll never live in one. Regarding the gas seal yes my current exhaust silencer is never going to be factory fresh again, its scuffed and bashed up and as you say ive only knocked it back into shape enough to fit.. I do have a spare silencer in the shed in the UK so I might swap that back on in the summer, at that point it might be a gas tight and better fit. Thanks.
That is a good point, can anyone confirm that for us?
Wld leave it standard myself.
much cleaner lines .
Thanks Mred. Agree it looks a look better, sound is a bonus 😊
Should have kept plastic bag on stop it getting dirty!! 😂
There's no stopping this bike getting dirty with the amount of dust we have over here!
How come Indian can still field an 1800cc fully air cooled engine and BSA can't? Can't get past the Morris Minor slab of a radiator.
I imagine BSA did not choose a 1800cc air cooled V twin for the following reasons:
A) it would be price prohibitive, for the desired market segment
B) they wanted a single not a twin for heritage reasons
C) power output would necessitate other changes to drive chain, chassis and brakes
D) The weight of the bike would increase
E) unacceptable delay to develop from scratch a v twin aircooled
F) Poor allocation of R&D resources
I could go on... basically the same reason you don't see an inline 4 supercharged motor putting out 200hp in a Royal Enfield Bullet 350...
I've seen it all now, using logs of wood & molegrips to bend brackets, then you clean dirty silencer only to scratch the fuck out of it on pavement!
And the award for least aware commenter goes to... 😂. We're on an Spanish island with limited tools did you not see the reg plates! The silencer was scratched from an accident in November which I spoke about multiple times. You've looked but seen nothing.
"Limited tools" logs of wood hahahaha
Keep going... ☕️💷
Aah i see it’s marked it’s spot.
It sounds like a bike now.
Thanks for the comment James, it's a lot better that's for sure.
Bike sounds like it can breath now. That's usually what I delete first on my bikes is the heavy, heat sink, bread box cats. Bikes run so much better without that Environment police garbage.
100%! Man thinks like me 😃👍
Sounds like a 125 with a noisy exhaust.
Removing the catalytic converter means removing the exhaust cleaning device, meaning becoming a contributor to smog and poluted air. Plus facing problems at the regular vehicle check, and possible police controls. Doesn't seem very mindful to me... if you want your new motorbike to produce pollution, why not save money and buy an old bike right away?
You need to give us time to read the onscreen text, it disappears much too quickly and we can’t read it all!
That's good advice m, thanks Nick. Currently left on the default which is 5 sec IIRC. Will make it longer next time. Cheers.

Unusual word choice from a guy who names himself after an SS tank commander 🤔
IT's still a boat anchor and a poser magnet.
A lot of work went into designing and building the new BSA, a challenge to get right given the history of the marque. Many people are happy enjoying these bikes which dont cost a lot and ride great. You, on the other hand, are up watching RUclips at 2 am trying to upset those people with a rude comment. Says more about you than the BSA.
Is IT
So you are making your bike pollute needlessly and you think that's a good thing?
I do indeed my friend. Let's not get into a debate about the environment 👍
Worry about China, not a motorcycle
@@RufusCapstick You will be crying when they exhaust tests like cars on MOT or crush bikes that have been decated
@@trevortrevortsr2 nope, it's easy to fit an exhaust for the purposes of an MOT. I do that with mine, takes half an hour.

Indeed. Man above probably doesn't realise kids are getting poisoned by extracting cobalt ore with their bare hands in Congo but he's guilt free driving a zero emissions vehicle. Life of vehicle emissions it's a cheap secondhand diesel everytime...
