I thought you said you were going to be speaking about it in great detail? You managed to get through the entire video without any detail whatsoever! Enjoyed the film though, glad you're happy and the condition of the R45 is a credit to you.
Ah. Guess your right but not a vast lot of detail to go over as the units just unbolt and replace. The NJB Shocks really seem to hit the spot but important to get the right spring for your weight. Thanks for watching 😀
When my dad is still alive, we had a shop that fixes and restores old bmw's 1968 and older, we didn't bother with the modern airheads, but we had a chance to have an R65, boy i loved it it's quick and nimbe enough feels like a dirt bike, that's where i found out why everyone is nut about the GS 😂
Never heard my 75/5 and 100/7 referred to as modern, but I'll take it. Still haven't seen a "CHECK ENGINE LIGHT" yet, on either one, haha. #1 Rule with an older BMW, famous last words "Wish l'd never gotten rid of it"
I’ve done it too Last winter. This Bike (R45 with the kit) from now on is my obsession. Especially: it reminds me extremely to my 750 Norton Commando, leaving a village, 5th gear- inhalating the throttle needles higher….
I bet the bike goes absolutely fantastic and I agree that the short wheelbase bikes are a pleasure to ride. I regretted selling my R65 to a friend so bought a 78 R45 which I converted using pistons and barrels from a R65. Just returned from a 800 mile tour of Devon and Cornwall, fully loaded and it never missed a beat. I also have a R80/7 so didn’t really need to upgrade to an 860cc, oh and I’m a bit too tight to shell out the cash needed. 👍
First of all I must say what a fantastic Austin 7 you have. Wow! A neighbour of mine has a 1929 Flat nose Morris and a 1929 Swift and I spent ages helping him restore it. I also was going the R65 Barrel and Piston route but I couldn't find them at a reasonable price. I have just completed the 500mile service and after resetting the valves it's running sweet as a nut. I love it to bits :) Suspension service next and then I may just swap the diff or get a higher ratio 5th as there is a, "Lands End to John o Groats in 24hours", run I want to do. Let me know if you want to join in :D
Great video! Nice one. Having ridden loads if Airheads over the years I'm hopefully about to actually buy my first. A wreck of a r75/5. If the deal comes off I'll have the restoration on my channel then it'll be used for a few trips away!
Thanks for your recommendation. I did it too, to my R45 -and what a JOY it is now. Easy to handle, and lots of power -even from 1500rpm. Great (45 year old) bike now.
Hi, thanks for the uploading, very hekpful to learn about this kit, just a couple of curiosity questions; do you modify carburator and valves as well? is the kit supplied with new valves? Is new cylinders generated torque compromising the transmission ? thank you !!
These old airheads are indeed still fun to ride. I have a 79 R100RS and each time I ride it, it still amazes me how good it performs. Bought it two years ago, won’t ever sell it. My wife will probably divorce me I do.
Bolting in the biggest engine you can start with is often pleasantly cheap, especially in the US where these machines sell for next to nothing being long obsolete for touring. Then add a displacement boost and it's all win.
Love the channel. I’ve just purchased a insurance right off not structural. All the work completed. I just received a new V5 just I’m going for the engine upgrade do you just get the engine capacity change on the V5 thanks again for the great video. 🏍👍
@richardlaker9722 I think the only thing I regret with my build was not going the full nut and bolt restore. It bit me a few times when oil started squirting out in odd places. But then again if it isn't leaking something it probably isn't working 😂 Have fun with the build. The 860cc kit is well worth it.
Hi. I now you may think that old Blighty is a bit grim and alright bits do fall off and get washed away in the winter but the summer this year we regally saw 35c and even on occasion 40! I was still out on though having fun..... and alright, roasting my nuts off :D
Hi. I didn't get the camshaft. As the bike runs so much better and even smoother I don't think it is high in my upgrade list. I wanted enough power to safely overtake and keep us with my friends. What I have got is a whole lot more. My next upgrades with be sorting out the suspension and possibly a r100 diff as there is now so much more power I'd like to reduce the revs at 70mph by at least 500rpm. Safe riding 😀 David
Did a similar upgrade on my wife's R65 about 30 years ago. But one thing led to another, ended up changing out the final drive, heads, carbs etc. I wish I could have found a wrecked R100 or R90 and used th parts from that. Could have saved me a lot of money.
The quote is 45bhp with 75 torque. What it equates to is a very usable bike that can do an easy 80 or 90 if you can hang on. Needs a r100 diff I think 🤔 as it revs a little high. About 5k at 70mph.
Morning just wondering how you got on changing your V5 details from a r45 to a r 83 can you please let me know. I’ve just ordered my up grade kit thanks love your channel. 🏍👍+ How long before you receive your updated V5 thanks again 🍰🥟🍔 yum😋
For a classic motorcycle some engine modifications are permitted so I did not change anything. Look it up on the DVLA website. (Queue inbound hate mail 😁
This is the bit I looked at taken from the DVLA website The following are considered acceptable (not substantial) changes if they fall into these specific categories: • changes that are made to preserve a vehicle, which in all cases must be when original type parts are no longer reasonably available; • changes of a type, that can be demonstrated to have been made when vehicles of the type were in production or in general use (within ten years of the end of production); • in respect of axles and running gear changes made to improve efficiency, safety or environmental performance; • in respect of vehicles that have been commercial vehicles, changes which can be demonstrated were being made when they were used commercially.

On Power, I had an R65 for about 3 years. I ran with others who mostly had R100's but didn't lag behind much as it got up to 110 mph (indicated) very quickly the few times there was a straight road and no police. After that it was a series of R100RS's which I took to top speed a few times but mostly only used the power to pass. I noticed it stumbled right around 100 mph. On having to do a top end I asked to put in dual plugs and a few other mods but nothing which would hurt the engine's reliability. With that I could get it up to 125 very smoothly from it's stumbling to 120 beforehand. Now I have an F800 which is a wonderful performer but seldom bring it above 80 and have never taken it to full speed. None the less it's always satisfying to know your machine is running at it's peak.
You may be interested in a story that illustrates the interchangeability of BMW parts. Many years ago prior to the whole GS craze that started with the R80GS a guy called a Lindsay Urqhart who was the Australian BMW manager built a bike and sidecar racing ace built a trail bike GS largely styled after the BMW ISDT bikes. It looked fabulous but the interesting point was, he used an R100 engine but with an R65 crank and shortened cylinder barrels. This gave about 800cc with a bore and stroke combination not seen on any BMW at the time. I read a review of the machine which was mainly positive. The bike had Maico twin shock suspension and really did look great. Sadly it’s current whereabouts are unknown. Many manufacturers don’t reinvent the wheel with every model. Design engineers use many design solutions across many models and years. Take a look at 70s to 90s gear selector ratchets which were largely the same across both road, trail and mx bikes. Harley Davidson does the same which allowed me to use front brake and suspension parts from bikes as late as 2010 on my 1978 machines, turning old bikes into well braked and safer pieces of equipment. Never sell a BMW is my advice as every time I get back on after a long lay off I am reminded of BMWs slogan from the 70s that read, ‘Sheer riding pleasure’. I have three and love them all.
That's a really interesting story. I'm thinking they must have modified the barrels a little as there wouldn't be enough compression otherwise. The setup must be very similar to what I have now with a 60 kit. I'll be looking that story up. Thank you 😊
I have a photo of the bike in a scrapbook somewhere in storage but Peter Thoeming aka ‘the Bear’, at times editor and contributor of various Australian motorcycle magazines was aware of the machine and as he told me, once passed on purchase of that machine at an auction. Yes I am sure that the barrel height must have been shortened. At the time I wondered what this must have done to the relation of the pushrod tube alignment. Probably would have to taken height from the head end.
@@stephensaunders4668 I found this about the bike. www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwjAnp_Ki7D_AhV6RvEDHdBaAFIQFnoECAsQAQ&url=https%3A%2F%2Fwww.pressreader.com%2Faustralia%2Fold-bike-australasia%2F20200806%2F282535840695471&usg=AOvVaw0EuJ1SUE-d1tLgbcl4szZj
Entertaining video, many thanks! As a returning biker I considered getting an R Ninety T but really don’t need the full capability it offers. Your R45 looks great and I was wondering if it may be too small for someone 6’ 1” ish?
Hi Endo, I tried the R9T too and it's a great bike but I felt that the R45 had something different that a modern bike can't offer which was why I spent the extra to make it into a 860cc and that made it very usable. I am only 5'6 but the man who I bought my R45 off was in fact my ex-boss for 7 years and he used it regally for years. He is 6'2. The R45 and R65 do have a shorter swing arm and seat than the R80 and R100 but exactly the same frame and most of the engine. IMHO I think the R45 is too underpowered to be anything but a short hopper. Lovely but frustrating at the same time. I'd look for a R65 or R80 unless you feel happy about fitting an upgrade kit... and better brakes :)
Hi Endo, I am 6'2" and feel very comfortable on an R45 BUT with lowered footrests and an upholstered saddle. Save ride, a happy christmas time 🎄 and best wishes >Lutz
Good morning. I watched your video for another time, thanks a lot for the riding and beautiful landscape scenery imaginary reviews, my BMW does not work in the last 3 weeks exactly. Problem with spark fire between 2000 and 3800…. Crankshaft. Today I will make another try. I fixed everything controlled and new. Even checking the Carburetor. When Troubleshooting goes on, I will check the ‚Fliehkraftregler‘ She really reminds me of my Vampire Motorcycle Commando. I put in a Boyer Brandson Electric Ignition, problems gone, but many more output of power, american Cylinder Head and MK2 or Mikuni Single Carb. Life goes on- I dream about Scotland another time. Across England by Ferry. And the BMW (black Princess). Best regards.👩🏿🦳🐶
Hello Jochenwagner. Sounds like it's ignition related. Have you checked the little springs that advance the spark in the bean can? It's worth taking the whole thing off and examining. Also, this could be caused by a loose timing chain. Lastly, I'd change the points and condenser unless yours is electronic. Hope it's fixed soon :)
@@theoldgraywindpassertest New: Condensator, Contact breaker. Spark- plugs, cap, and cable. Ignition checked, contact breaker 0,4. Carbs checked and cleaned.Some new parts and gaskets/ O- Rings……… Best regards!🍀
I bought one ready converted and really like riding it - it feels like you're going faster than you actually are! One change I made is to fit an r65 final drive and speedo because like you I found it too revvy on the open road - it's 12% higher and fourth gear is now equivalent to my old fifth. Can I ask you if you find that if you open the throttle in say 4th gear at around 2800rpm it vibrates till 3000rpm and then pulls hard? I don't know if I am bogging it down and this is normal or if it is a tuning issue
Hi Paul. That's exactly what I was thinking of doing and glad to hear it worked. May I ask what final drive ratio you fitted? I too have a vibration at somewhere in the range, I think it's about 4k then goes but I'll get back to you on that. I thought it may be mechanical which it may very well be if we have the same symptoms but if mine is different I think it could just be carb balance. Glad you like it. Fitting the kit was a last ditch before I bought an R9T but now I'm keeping it :)
@@theoldgraywindpassertest So I have a 31/9 final drive fitted to answer your question . As to the vibration- I think it isn't mechanical because it only happens when you open the throttle so will work towards getting everything set up right - as I'm new to airheads it is a steep learning curve for me. I fitted a siebenrock front brake upgrade when I got the bike in spring because I really didn't like the original ate setup btw
@@paulalig761 Thanks for that Paul. I'll be looking out for one now :D If your near to Lincoln, Rainbow Workshop is your man for setup. My R45 came with 2 disks but only one calliper so I fitted a second calliper and Goodridge hoses. Stainless steel disks are not very good stoppers anyway but adding that second disk meant that I didn't have to send a pigeon ahead of me with a note strapped to it's foot saying, "LOOK OUT BEHIND!!!!"
Hi, I got the Mini Puig screen as it seems to be in keeping with the bike and a better quality than the cheap Chinese one I had before. Here is the link and I recommend Louis Moto, they have never let me down... admittedly only used them twice though :) www.louis-moto.co.uk/artikel/puig-mini-screen-with-mounting-kit/10006508?filter_article_number=10006508
Hi, thank you for the video. My name is Lutz living in Wuppertal (the city with the suspension train) / germany. I ride an R100GS PARIS DAKAR 1989 but searching for a smaller, lighter Airhead => so you showed me the perfect solution!!! Siebenrock is a well known german brand and Hans-Joachim Siebenrock is a technical engineer who founded in 1984 (when I was 20 years old) his company. You have a beautiful bike, I like the colour very much! Is the colour original? Where do you have this tiny little windscreen from? Best wishes, allways a safe ride and a happy christmas time >Lutz
Hi Lutz, Great to hear from you. I absolutely love my Siebenrock kit. It makes it very usable. Bear in mind that after the upgrade you may need to find a R100 final drive to keep the RPMs down. The screen I use is the Puig Mini. Here is a link, www.louis-moto.co.uk/en/puig-mini-screen-with-mounting-kit-10006508 The Gold colour is copied from the original. Maybe there is a tiny bit more sparkle but that's very close. Take care. Regards, David

Morning many thanks for the information you sent me. Just wonder your thoughts 1. Because my r 45 was a insurance right off not structural it was stolen. It will need a mot to prove it’s road worthy I presume the new mot will still show the bike as a r45 because the engine and frame number are still the same. 2. When I come to insure the bike I tell them it’s a r45 with a engine upgrade. Just going for another coffee and maybe a 🧁 😋 and read all the information you sent me. Thanks again for your help on this matter looking forward to receiving my upgrade kit. Enjoy your channel very much. 🏍👍
Hi. Surprisingly I haven't done a thing with the carbs. I thought I would need to rejet too but carberation seems to be spot on. I've done about 600 miles so far but after 1st run in service, plugs plus looks fine and in fact it runs very sweet.
Hi there , i want to do the Same on my r45 (BY 11/1981) Most tell me that i MUST use the 32 bing carburators (r80 for example), instead of the Original 26 bings. Please let us know if and what you rejettet. Greetings from Germany, Daniel
@@leinadj.7948 Hi Daniel. I thought exactly the same but I am using the original carbs with no changes at all. I've pulled the plus several times but they seem the correct colour maybe even a little rich and as it really is running very smoothly I have just left as it is. I'm not sure if mine are 26mm but they are the flat top Bings that came with the bike. I'll try and find out for you. I was also thinking that if you pull twice as much air through the carbs it would certainly need re-jetting but apparently not :) If I had not of fitted the kit I would probably have sold the bike by now because as standard it really is no faster than a 125. So my advice is, fit and enjoy the bike. You will get stopped most places by people asking about it which is sort of nice :D Regards, David
@@theoldgraywindpassertest Hi David, Thank You very much for your answer !!! I will order the kit tomorrow and looking forward of having fun with the R45 Plus ;) Here in the german forums for the "small" Boxers , they are always very sceptical by NOT using 32er Bings. I asked them , and it turned out these forum users are NOT driving a R45 with the 860 Kit 😆 it is typical for us germans to question everything !!!!!!! would be very happy to read more from your experiences 😃 keep going on !!!! greetings from germany , daniel
@@leinadj.7948 Hi Daniel. Tomorrow morning I will get the serial number from the carbs. From there we can check what mm it is as I have a feeling the 45s were different from EU for some reason. Take car, David
I used to really like my old R45 for short hops. I also ran a Laverda Mirage 1200 at the same time, and that provided the thrills , when I needed them. Nothing wrong with the R45.
It was well worth the cost. It makes the bike ridable and more like a modern bike. I guess it really depend on how much your prepared to put into it of course as really, it's lost money.
Today i finished the 860 rebuild !! I changed from Solo ATE Brake to Double Brembo Discs. Carb is a Bing 32 with a 145 mainjet. End gear ratio changed to 32/10. Runs like hell !!!!! Should have done this years before !!! No more hurting the engine with 6000 plus RPM just for passing a car or so.
Fantastic! Sounds like I'm going to have to get a new final drive ratio fitted too. Really, nothing beats the smile on my face when I return to the bike and find a little cluster of people gathered round it :D
@@theoldgraywindpassertest Indeed :) Love to ride the "R86" so much !!! Furthermore , i installed the YSS and its sooo fun to ride the Bike with thesse new shocks. But the next shocks should be oldstyle shocks , where the whole shock is covered. doesnt know if YSS offers them now in germany... Greetings from germany, Daniel :)
@@leinadj.7948 Hi Daniel 👋 ☺️ When I bought new shocks it made the world of difference to the handling and comfort. Mine are fully covered. I got them from a company called NJB Shocks. Now I just have to do the front suspension 😁

Tell RUclips that your videos aren't being watched anymore because of ads.
Maybe 😀
866cc is a good product upgrade … but this video … one can easily do without …
Just editing the next video and that one is definitely not worth watching 🙃
Did a similar upgrade on my wife's R65 about 30 years ago. But one thing led to another, ended up changing out the final drive, heads, carbs etc. I wish I could have found a wrecked R100 or R90 and used th parts from that. Could have saved me a lot of money.
The good thing about this kit is that it's designed to run using the same carbs and heads. I have now swapped the diff though 😀
@@theoldgraywindpassertest Yes but I think you would want to switch some more parts out.
Beautiful video, but does not deliver what it promises about performance increases, and how to do it, so it’s a time waste bait and switch
I clearly remember the Motorcycle News (newspaper) headline at the introduction of the R45 and R65 "Sluggish Snails"
They were spot om!
Ahh, reminiscing about the days of riding down Long Causeway eh? :D
Well spotted! :D
Now I want one but would settle for an R65👍
R65s are a great bike and easier to find than the R45. That also have little upgrades added too 😃
Wonder what that increases power to ….60-70bhp maybe?
The quote is 45bhp with 75 torque. What it equates to is a very usable bike that can do an easy 80 or 90 if you can hang on.

Hi Paul. Always trying to have a little bit of fun 😁 Glad to see you 🙂
and when they drive it is always a crap experience🤣🤣🤣🤣🤣🤣🤣 amazing!!!!
Depends on where you are 😉
You may be interested in a story that illustrates the interchangeability of BMW parts. Many years ago prior to the whole GS craze that started with the R80GS a guy called a Lindsay Urqhart who was the Australian BMW manager built a bike and sidecar racing ace built a trail bike GS largely styled after the BMW ISDT bikes. It looked fabulous but the interesting point was, he used an R100 engine but with an R65 crank and shortened cylinder barrels. This gave about 800cc with a bore and stroke combination not seen on any BMW at the time. I read a review of the machine which was mainly positive. The bike had Maico twin shock suspension and really did look great. Sadly it’s current whereabouts are unknown. Many manufacturers don’t reinvent the wheel with every model. Design engineers use many design solutions across many models and years. Take a look at 70s to 90s gear selector ratchets which were largely the same across both road, trail and mx bikes. Harley Davidson does the same which allowed me to use front brake and suspension parts from bikes as late as 2010 on my 1978 machines, turning old bikes into well braked and safer pieces of equipment. Never sell a BMW is my advice as every time I get back on after a long lay off I am reminded of BMWs slogan from the 70s that read, ‘Sheer riding pleasure’. I have three and love them all.
That's a really interesting story. I'm thinking they must have modified the barrels a little as there wouldn't be enough compression otherwise.
The setup must be very similar to what I have now with a 60 kit.
I'll be looking that story up.
Thank you 😊
I have a photo of the bike in a scrapbook somewhere in storage but Peter Thoeming aka ‘the Bear’, at times editor and contributor of various Australian motorcycle magazines was aware of the machine and as he told me, once passed on purchase of that machine at an auction. Yes I am sure that the barrel height must have been shortened. At the time I wondered what this must have done to the relation of the pushrod tube alignment. Probably would have to taken height from the head end.
@@stephensaunders4668 I found this about the bike. www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwjAnp_Ki7D_AhV6RvEDHdBaAFIQFnoECAsQAQ&url=https%3A%2F%2Fwww.pressreader.com%2Faustralia%2Fold-bike-australasia%2F20200806%2F282535840695471&usg=AOvVaw0EuJ1SUE-d1tLgbcl4szZj
Hmmm, can’t get that link to open. Might be a sign I need to update my software.
Entertaining video, many thanks! As a returning biker I considered getting an R Ninety T but really don’t need the full capability it offers. Your R45 looks great and I was wondering if it may be too small for someone 6’ 1” ish?
Hi Endo, I tried the R9T too and it's a great bike but I felt that the R45 had something different that a modern bike can't offer which was why I spent the extra to make it into a 860cc and that made it very usable.
I am only 5'6 but the man who I bought my R45 off was in fact my ex-boss for 7 years and he used it regally for years. He is 6'2. The R45 and R65 do have a shorter swing arm and seat than the R80 and R100 but exactly the same frame and most of the engine.
IMHO I think the R45 is too underpowered to be anything but a short hopper. Lovely but frustrating at the same time. I'd look for a R65 or R80 unless you feel happy about fitting an upgrade kit... and better brakes :)
@@theoldgraywindpassertest Thanks for the advice!
Hi Endo,
I am 6'2" and feel very comfortable on an R45 BUT with lowered footrests and an upholstered saddle.
Save ride, a happy christmas time 🎄 and best wishes >Lutz
I already have a r100 mono shock but for some reason now want a r65 too😂
Ah, I understood the mono handling of bumps was far superior 😌 mind you, airhead owners have a habit of collecting 😀
Good morning.
I watched your video for another time, thanks a lot for the riding and beautiful landscape scenery imaginary reviews, my BMW does not work in the last 3 weeks exactly.
Problem with spark fire between 2000 and 3800…. Crankshaft.
Today I will make another try. I fixed everything controlled and new.
Even checking the Carburetor.
When Troubleshooting goes on, I will check the ‚Fliehkraftregler‘
She really reminds me of my Vampire Motorcycle Commando.
I put in a Boyer Brandson Electric Ignition, problems gone, but many more output of power, american Cylinder Head and MK2 or Mikuni Single Carb.
Life goes on- I dream about Scotland another time. Across England by Ferry.
And the BMW (black Princess).
Best regards.👩🏿🦳🐶
Ah!
By bike I cannot have the best passenger- my dog.
Hello Jochenwagner. Sounds like it's ignition related. Have you checked the little springs that advance the spark in the bean can? It's worth taking the whole thing off and examining. Also, this could be caused by a loose timing chain. Lastly, I'd change the points and condenser unless yours is electronic. Hope it's fixed soon :)
I know that feeling :)
@@theoldgraywindpassertest New: Condensator, Contact breaker. Spark- plugs, cap, and cable. Ignition checked, contact breaker 0,4.
Carbs checked and cleaned.Some new parts and gaskets/ O- Rings………
Best regards!🍀
@@jochenwagner5170 Looks like you have tried a lot of things. Valve clearance done? Also, could it be a coil going bad? 🤔 So many things 😀
nice looking bike. Beautiful country-side.
Thanks Edwin. I live in Sheffield so being next the the Peaks is great. There are so many nice places still to explore though. 😀
I bought one ready converted and really like riding it - it feels like you're going faster than you actually are! One change I made is to fit an r65 final drive and speedo because like you I found it too revvy on the open road - it's 12% higher and fourth gear is now equivalent to my old fifth. Can I ask you if you find that if you open the throttle in say 4th gear at around 2800rpm it vibrates till 3000rpm and then pulls hard? I don't know if I am bogging it down and this is normal or if it is a tuning issue
Hi Paul. That's exactly what I was thinking of doing and glad to hear it worked. May I ask what final drive ratio you fitted?
I too have a vibration at somewhere in the range, I think it's about 4k then goes but I'll get back to you on that. I thought it may be mechanical which it may very well be if we have the same symptoms but if mine is different I think it could just be carb balance.
Glad you like it. Fitting the kit was a last ditch before I bought an R9T but now I'm keeping it :)
@@theoldgraywindpassertest So I have a 31/9 final drive fitted to answer your question .
As to the vibration- I think it isn't mechanical because it only happens when you open the throttle so will work towards getting everything set up right - as I'm new to airheads it is a steep learning curve for me. I fitted a siebenrock front brake upgrade when I got the bike in spring because I really didn't like the original ate setup btw
@@paulalig761 Thanks for that Paul. I'll be looking out for one now :D If your near to Lincoln, Rainbow Workshop is your man for setup.
My R45 came with 2 disks but only one calliper so I fitted a second calliper and Goodridge hoses. Stainless steel disks are not very good stoppers anyway but adding that second disk meant that I didn't have to send a pigeon ahead of me with a note strapped to it's foot saying, "LOOK OUT BEHIND!!!!"
Interested in what windscreen you have?!
Hi, I got the Mini Puig screen as it seems to be in keeping with the bike and a better quality than the cheap Chinese one I had before. Here is the link and I recommend Louis Moto, they have never let me down... admittedly only used them twice though :)

Great video I enjoyed this, I like your style :)
Thanks fella. Love your crosser videos too! I'd really like some off road action too 😁
Have you tried the 250R
Hi. No I haven't. Is that the R27?
Hi,
thank you for the video.
My name is Lutz living in Wuppertal (the city with the suspension train) / germany.
I ride an R100GS PARIS DAKAR 1989 but searching for a smaller, lighter Airhead => so you showed me the perfect solution!!!
Siebenrock is a well known german brand and Hans-Joachim Siebenrock is a technical engineer who founded in 1984 (when I was 20 years old) his company.
You have a beautiful bike, I like the colour very much! Is the colour original?
Where do you have this tiny little windscreen from?
Best wishes, allways a safe ride and a happy christmas time >Lutz
Hi Lutz,
Great to hear from you. I absolutely love my Siebenrock kit. It makes it very usable. Bear in mind that after the upgrade you may need to find a R100 final drive to keep the RPMs down.
The screen I use is the Puig Mini. Here is a link,
www.louis-moto.co.uk/en/puig-mini-screen-with-mounting-kit-10006508
The Gold colour is copied from the original. Maybe there is a tiny bit more sparkle but that's very close.
Take care.
Regards,
David
@@theoldgraywindpassertest Hi David,
thank you for your answer and the link to the tiny screen . . . sadly the clear one is not available. But nevermind.
Best wishes >Lutz
Morning many thanks for the information you sent me. Just wonder your thoughts 1. Because my r 45 was a insurance right off not structural it was stolen. It will need a mot to prove it’s road worthy I presume the new mot will still show the bike as a r45 because the engine and frame number are still the same. 2. When I come to insure the bike I tell them it’s a r45 with a engine upgrade. Just going for another coffee and maybe a 🧁 😋 and read all the information you sent me. Thanks again for your help on this matter looking forward to receiving my upgrade kit. Enjoy your channel very much. 🏍👍
Have fun with the R45. I didn't need to change much at all with the upgrade. Not even with the carbs which surprised me. 😁
Awesome video. Great presentation
Thank you. I thought I could have done better really but at least I'm having fun. Thanks 😊
Nice one. What about the carbs? do they need rejetting? ot just swap piston gasket and cylinder
Hi. Surprisingly I haven't done a thing with the carbs. I thought I would need to rejet too but carberation seems to be spot on.
I've done about 600 miles so far but after 1st run in service, plugs plus looks fine and in fact it runs very sweet.
Hi there , i want to do the Same on my r45 (BY 11/1981)
Most tell me that i MUST use the 32 bing carburators (r80 for example), instead of the Original 26 bings.
Please let us know if and what you rejettet.
Greetings from Germany,
Daniel
@@leinadj.7948 Hi Daniel. I thought exactly the same but I am using the original carbs with no changes at all. I've pulled the plus several times but they seem the correct colour maybe even a little rich and as it really is running very smoothly I have just left as it is. I'm not sure if mine are 26mm but they are the flat top Bings that came with the bike. I'll try and find out for you.
I was also thinking that if you pull twice as much air through the carbs it would certainly need re-jetting but apparently not :)
If I had not of fitted the kit I would probably have sold the bike by now because as standard it really is no faster than a 125. So my advice is, fit and enjoy the bike. You will get stopped most places by people asking about it which is sort of nice :D
Regards,
David
@@theoldgraywindpassertest
Hi David,
Thank You very much for your answer !!!
I will order the kit tomorrow and looking forward of having fun with the R45 Plus ;)
Here in the german forums for the "small" Boxers , they are always very sceptical by NOT using 32er Bings. I asked them , and it turned out these forum users are NOT driving a R45 with the 860 Kit 😆
it is typical for us germans to question everything !!!!!!!
would be very happy to read more from your experiences 😃
keep going on !!!!
greetings from germany , daniel
@@leinadj.7948 Hi Daniel. Tomorrow morning I will get the serial number from the carbs. From there we can check what mm it is as I have a feeling the 45s were different from EU for some reason.
Take car,
David
R45 was a complete dog of a bike
Cheers! :D I happen to like mine though ;) Probably wouldn't without the power upgrade kit tho.
I used to really like my old R45 for short hops. I also ran a Laverda Mirage 1200 at the same time, and that provided the thrills , when I needed them. Nothing wrong with the R45.
Nice...but the cost eclipses the value of the bike. 🤔
It was well worth the cost. It makes the bike ridable and more like a modern bike. I guess it really depend on how much your prepared to put into it of course as really, it's lost money.
Today i finished the 860 rebuild !!
I changed from Solo ATE Brake to Double Brembo Discs.
Carb is a Bing 32 with a 145 mainjet.
End gear ratio changed to 32/10.
Runs like hell !!!!! Should have done this years before !!!
No more hurting the engine with 6000 plus RPM just for passing a car or so.
Fantastic! Sounds like I'm going to have to get a new final drive ratio fitted too.
Really, nothing beats the smile on my face when I return to the bike and find a little cluster of people gathered round it :D
@@theoldgraywindpassertest
Indeed :) Love to ride the "R86" so much !!!
Furthermore , i installed the YSS and its sooo fun to ride the Bike with thesse new shocks. But the next shocks should be oldstyle shocks , where the whole shock is covered. doesnt know if YSS offers them now in germany...
Greetings from germany, Daniel :)
@@leinadj.7948 Hi Daniel 👋 ☺️
When I bought new shocks it made the world of difference to the handling and comfort. Mine are fully covered. I got them from a company called NJB Shocks.
Now I just have to do the front suspension 😁
@@theoldgraywindpassertest
NJB , i will look for them :)
For my front susp. i used WILBERS and SAE10 , with this configuration it fits perfect for me :)
@@leinadj.7948 Thanks for that. I think that will improve comfort greatly 😀
😒 p̾r̾o̾m̾o̾s̾m̾
As an engineer, I regard your misleading video title as ‘clickbait’. Nothing about the upgrade, just you rambling about motorbiking.
Thanks Lesley. I thought I had clearly mentioned the 860cc upgrade kit I have fitted. I'm just a bloke having fun with some spanners, oil and a bit of wind. 😉
If only I was female and hot, I'd be keenly making money out of this but instead all I get is a little fun. I hope you have fun too.

...and very badly at that
What a plonker
Great video.
cool
Thank you 😊
Beware of Evil Highspeed Speed Wobble 😨
High speed? 😂😂😂
Just get an R65LS saves all the hassle
But there is a big difference in 650ccm and 860ccm. ;-)
