Videos of my 1971 Norton Commando. I bought it in 1984, rode for a couple years then parked it, covered it, and dreamed about restoring for the next 32 years. Seems like that happens to a lot of them. It was a street scrambler from the factory, but i prefer the look of the roadster. It was a rolling basket case until i tore it down in 2018. It needed virtually everything. The frame, engine, transmission are matching numbers. The only thing left original are the fork sliders, wheel hubs, frame, engine, transmission, triple tree. It got all the reliability goodies/mods. I finished it in 2020 after 21 months. I hope you enjoy the videos. I will have more as time passes.
Norton after setting time
I'm trying to figure out the problem with idle on this machine. Brian from Australia has volunteered to help. This video is for Brian to hear what it's doing. It's pretty boring.

1st run after carb modification. Kinda cold out, 46°. Can't wait for better weather.
Amal 930 pilot circuit modification

A video showing a modification I make to the Amal MK1 concentric carburettor. I install a short pick up tube to draw fuel directly from the bowl to eliminate the problem with the bowl warping and losing the seal between the bowl and the carb.
1971 Norton Commando first start

After sorting out the ignition situation, I finally get a chance to start the Commando. Unknowingly, one of the carburettor slides was stuck open a bit causing a very fast idle.
1971 Norton Commando first attempt to start

The first attempt to start the Commando. The magnetic rotor indicates both TDC and BDC timing. I apparently used the BDC not realizing it. Confusing. I won't forget that one. There are instructions making one aware of that!

Walk around after the first start the day before. First ride up the street.
1971 Norton Commando at Mid Ohio 2021
Просмотров 6472 года назад
A gopro video of the "lap for history" ride at Mid-Ohio Sports Car Course in Lexington, Ohio on 7/24/2021 aboard a 1971 Norton Commando with my buddy riding his 1975 Norton Commando Electric Start. Jump ahead to 6:45 for a little more speed down the back straight.
A lot of the effort used here is going through the rear suspension. Try sitting or standing astride it or on the centre stand .I would never start it in that manner but i have been starting big twins for 50 years
Back.in the day one of my riding companions had a 1969 Norton Commando Fast Back, in dark green. The thig I most remeber was when he broke his leg just before the Islebof Man TT So he welded a stantion out of the head stock, as it was his brake leg .to rest his leg on. He road 200+ miles there, then 200+ back with his girlfriend on pillion 😂 top til.mate, never kick a bike on the side stand, you'll all end up on the floor.
As a 73 norton comando past owner i can relate but after you get the hang of it you will have very little trouble .Brings back memories .
In 1971 at a dealer in DFW area I traded my 70 bsa lightening for 71 Norton fastback (fiberglass metalflake tank and rear fender) It was a beauty, put dunstall pipes on it. ❤
🙄🙄🙄
Ouch said the sidestand.
Hey, it’s a Norton. Didn’t expect it to be easy, did you?
I bought mine aged 18 in 1977. Being 18 helps a lot, but please don't kick it over on the side stand, sit astride or use the centre stand. If it ever fires up, but immediately cuts out, it's possibly the kill switch (yes, it can fire but just for a second). You might like to now that in 1977 a Queen's jubilee Bonneville cost £749, whereas a Commndo cost £1,600. A good bike forr the taller chap, I'm 6'2".

Great way to break a leg. 😮 *DON'T* leave your weight on the starting foot.
I remember when these first came out , saw one do 128 mph over a quarter mile at a drag meeting.. Conan UK
That's amazing! Mine won't do that, I have it geared up as high as I can get it.
IT'S FAILURE NORTON COMMANDO BY BRITISHERS. TRADITIONAL OIL LEAKS.
It's fuel. I'm surprised you couldn't tell.
If a Commando do not start with max. two kicks, it has some issues with ignition or carburettors.
Exactly sir!
Good grief the starting procedure for this or any similar British Big Twin is: open fuel tap. Depress ticklers on both carbs till petrol runs out; open throttle no more than 1/8; get to tdc; kick. If she don't start after 3 or 4, check for spark. Oh and they had a completely ridiculous kill button which needed to be in circuit but frequently wasn't. Usually if you just flicked that button (it's red) that would get contact back and bingo. (These switch clusters were not very waterproof.) A lot of us just ended up wiring that button out because it was such a total PITA.
Some people just don't know how to start them i never had any trouble starting my bikes
Same here. If no joy after 3, some problem somewhere.
Sure way to break a leg (at least). STAND ASTRIDE!
No. Better to start on the centre stand and stand beside the bike. You can start them astride but it's harder. Never trust the Norton sidestand, it was designed by Beelzebub in person
@@RodFleming-World .... "Mr DANGEROUS" I'd say Rod Fleming - and would say that as LOUDLY as I can. I genuinely worry: I'd say it's fine to start a Commando on (or off) its centre stand SO LONG AS you are only ever doing so astride the bike and absolutely NEVER while standing beside it. I'd say standing beside it makes a broken ankle, leg and/or pelvis quite likely. And I wouldn't even THINK of trusting the Norton's side stand for anything, I'd say designed by Beelzebub's 3-year-old.
You big dummy you flooded the carbs here. When I had my commando it started on the first kick!
I just added a video of my 73 750 , same colour as well .
Nice bike. Sounds great. Love these old bikes. Enjoy.
Thank you, I appreciate that.
If it's not a worn out carb then it's an air leak on the inlet port - either the carb connections or judging by the oil coming out of the LH side, pipe out of spec valve guides. Standard guides are useless - they bell inwards on fitment and the i.d is too big from the start. Looking and listening to the videos you still have problems - lots of oil smoke from LH cylinder on start-up - you need to strip down the top end and do it properly - send the entire top end off to a proven Norton shop.
Is that a standard engine (sounds good when revved 😊)?
Yes sir, it is bored .020" over.
Credit the original designers with some knowledge. If the idea is to compensate for warped float bowl surface flatten the surface. No need whatsoever for your modification.Better off replacing the original carbs with Amal Premiers.
If you know anything about the Amal MKII, they did just that.
@@nicksnorton2340 But you're using the Mk1's which work very well as long as there is no wear between the slide and body which, on the original design wear extremely quickly due to slide and body material being the same. Fit the Amal Premiers and you'll have no problem as long as you get the air:fuel ratio checked for your bike. P.S there is no extended tube on MK2 Amals
I didn't see you use the choke. If the engine was cold on start up they need the choke for them to run at idle from cold - if they don't need the choke then the mixture is too rich on the idle circuit. If you have the Premiers fitted you can change the pilot jets. If you don't have Premiers then fit a pair - the original Amals where cheap at best. Best thing to do is get it on a dyno where you'll get a graph print out of the air:fuel ratio through the rev range. The engine is burning oil too - needs the top end doing properly.
I always use the choke as well as the tickler. Unless it's been ridden earlier.
@@nicksnorton2340 Looked like the choke was in the open position on the second, "first start up" video.
It's a shame - another example of more time spent making a bike look nice rather than time spent making sure it's going to start, run right and be reliable - at least you should have learnt something, good luck for the future!
Obviously, you weren't there for the restoration. I did make a few mistakes. However, there was more than just "show" done on the project. I made all the reliability upgrades I could do. Thank you
@@nicksnorton2340 You still have oil by-passing the valve guides and piston rings judging by your videos. Fit Kibblewhite guides which require reaming to size after installing and get the cylinder bore plateau honed when you fit new pistons. I highly recommend M.A.P lightweight pistons.
Sweet!!!! Love the way all cycle parts wobble around like a bowl of jelly _ Proper Norton. Keep it up.
It looks so doodle against those stupid and shitty Harley’s !
What is this video for ?
It's someone trying to make out they know what they are doing when it comes to motorcycle engines/bikes (sadly in this case a Norton Commando) when in reality he dosen't have a clue. That bike is running badly after he carried out a useless carb mod which has made no improvement what so ever. I wish these types of owners would just admit their limitations and give the bike to someone who actually understands engines.
That looks like so much fun. Old Commandos are such great handling bikes, it must have been a pleasure on this road course.
Yes it was, too bad we couldn't go a little faster but nonetheless it's a great ride. Thank you for the kind comment.
Oh, and….it’s cool !
What model is this. Very nice
It originally started out as a street scrambler. I restored it to a standard roadster. Thank you for the kind compliment.
@@nicksnorton2340 I bought part of an estate the had a bunch of Norton parts that I have been selling on ebay so I been looking on youtube for bikes that I can identify parts that are to same as mine so I was actually looking for specific names like Atlas, Dominator. Commando etc. Thanks
The engine sound is music 👍
That fast an idle on a Commando with cold oil will inflict life shortening harm. Should have shut it down immediately and checked the carbs then with engine OFF.
Sounds like you are having a fuel starvation issue. If you have the Premiers with the stayup floats you need to set the fuel level not the float level like you do with the old plastic floats.. You use an old drain plug with a nipple and some clear 1/4 fuel line to make a utube. Most Brit bike Amal suppliers have a kit availble or they are on ebay. With the utube zip tied to the side of the carb turn the fuel on and measure how high it comes in the tube. What you are shooting for is about .21" below the top of the float bowl(not the top the gasket). If it is low, take the bowl off and gently bend the metal tangs on float up so that it sits higher in the bowl. With the stay up floats this generally means the top of float is parallel with the top of bowl and slightly proud of the top when it is close. Usually if you get it too high the needle won't close and the carb will drip gas. This may take a few back and forths to get it right but it will make the bike idle a lot better.
Nice bike. Sounds good. As a fellow Norton owner, I'm curious about why the rear fender and taillight occasionally bob up and down at idle. It looks like the rear frame member supporting them isn't welded to the main frame tube. Is there something you've modified to cause this?
No sir, it is indeed welded, i did not weld a longer gusset of what is available. I've seen mine as well as others do the same thing. The camera "strobes" the vibration to make it appear like it's slow moving up and down.
@@nicksnorton2340 Interesting. I just hadn't thought I'd seen that movement in any of the other videos of Nortons I've watched, but perhaps, as you suggested, it's a camera effect. In any case, very nice Norton. Enjoy your rides. I know I do on mine 👍.
Not the most exciting presentation, but fortunately this beautiful bike in that colour does a lot of talking itself.
Thank you
A nice modification would be an acceptable upgrade to round slide Mikuni carburetors. They perform reliably and the adjustments are spot on. I swapped from 40mm Bings to 38mm TMX flat slide Mikuni’s on my BMW R100 CS. Much better.
Everyone said that but when it raced against faster Hondas in the early seventies it took the round the corners every time !
Worst video ever. What a joke just listening to you start and warm up your Norton. Why don't you ride it and show what it can do. What waste of time. Not sure you m even deserve own that great of motorcycle
Had a Triton. Great frame but thank goodness the engine was a Triumph.
Beautiful bike. I feel for you man. They are not easy to kick over sometimes. My dad had a 73 850 with a rebuilt engine and the engine was so tight we ended up pull starting it with the car lol but it worked. Once running it ran like a bat outta hell. I swear it would lay rubber for about 30 feet.
Norton Commandos felt wheelies were undignified.
Master tuner
My norton is the same color :-)
what is the name of the color? i have forgotten.
My mate used to spend so much time getting his commando started that he used to leave it running and run into the boozer and sink a quick pint.occasionally it would dance across the courtyard on the centre stand and head for the kerb but he always managed to sink the last mouthful of beer before disaster struck.i never owned a norton but seeing this brings back great memories of my old biking days.
Must have been a pre-Isolastic Norton.
I've got a '69 XLCH. What you did there was just the priming kicks I need to start my mechanical chum. Yours is a beautiful bike. I'm jealous. My 'CH needs a garage buddy like your Norton. Airheads forever. Thanks for the vid. Sub/Likie
Thanks 👍
It's bad enough with a 65 Lambretta! Your Norton a very pretty ornament even she doesn't like to start.
Thank you. It starts on the first or second kick most of the time. I've got about 8900 mi on it now.
Great job. Even after surfacing my float bowls I had inconsistent idling with popping back. Your mod will fix it. I’m going the try the mod.
Great! i hope it works for you.
Saves on gym fees.
Cool! I've been the twice for the AMA Vintage Days a while back but I'm going this year, riding my bike from NC.
Very good. What will you be riding? Norton??
Sounds like the relay on the coils mod, trying to fix a non existent problem or one due to poor maintenance. Even on new Premiers I lap the bowl surface flat on a mini surface plate similar to Tornados reply. The gasket is sufficient in most cases to seal without lapping on new carbs. A lot less trouble than doing this and no problems with the idling over tens of thousands of miles. How did you check this was a problem?
I read about the gaskets leaking because the bowls weren't flat and sealing the port. I now don't think the gasket is the problem. I know the exhaust valve guide on the drive side is passing an excessive amount of oil, i believe since the rebuild. Another viewer commented about a condition caused by too much oil will disrupt the air/fuel mixture at idle. Everything i've tried has not worked leading me to take the head off and replace the valve and guide. This will be a winter project.
Sounds mean! Why do I cringe watching these older English bike being run on idle with no fan. Sure sounds crisp though.
Bit of smoke puffing when blipping throttle. When my 850 did that, found the original intake valve seals had gone brittle and crumbly...but yours should be new. Did you use updated Viton seals or stock? Also, the tiny oil drain hole on floor of intake rocker box, right side, partially under the spring seat (on the 850 anyway) can get clogged, leading to excess oil building up in the rocker, getting sucked past the intake or exhaust valve stems. I was able to clear mine using an extra long aerosol spray can straw (off a Seafoam can) and run it down nearly all the way to the timing chest where it takes a 90 deg bend. Must of had some debris in there as oil now drains much faster. In you case, idling on side stand could mean the oil is accumulating away from that drain hole and overfilling the rocker until you are upright. A Centerstand is a beautiful thing to have ;-)
