You didn't mention what ignition set-up you have. If you are still using points sometimes an old mechanical advance unit can hang up at an advanced ignition setting.

I have the boyer electronic ignition.

I had it installed by a local british bike friend. Are there any adjustments that need to be made to it? Is it possible its sending a a fast signal?

Also, i have had a couple people tell me i should buy a carb meter? Anyone know of one that works well with our bikes?

This was Just a stab in the dark, if you have electronic ignition I think it unlikely that over advancing at low speed is the problem. I would be inclined to run the bike up the road without an air filter and all the associated hardware, then you might visually see if the slides are sticking, lifting together, falling together, bottoming out correctly and that the slide adjustment screws allow the slides the full range of adjustment.

So i tried everything i could replace or adjust. The bodys and slide must have been just too worn. I'm giving up and buying a Mikuni 34mm Single carb.

I will post again what the final outcome is once installed and run.

I appreciate the suggestions and help!

My suggestion - dump the old Amals, put on Mikuni carbs and you can stop fiddling with carburation and just ride.

I have a single Mikuni (34 MM). Put it on a year ago and have never touched it since.

Good luck.

Alright.

I switched out the amal's for the Mikuni 34mm single card. Starts first kick. Idles great and run amazing!

The only issue i am currently having is in first gear, throttle closed the bike jumps / gallops unless i pull in the clutch and coast.

Any thoughts?

It's no secret that the kitted carbs come with rich settings. This is to protect the person selling the kit. All the power and risk is your's to own. Lean is the direction you seek but all the consistence you must also own. Jump in or quit.

Well I just just finished a 1969 Triumph TR6R for a customer. It took five hours to sort it,he left happy. He watched to whole thing and was educated as we went along. He was the owner from the beginning not too badly done but for some old road side repairs. A short list: Battery breather down a hole in the frame bad idea, some non-functional Japanese Zenor, Bad wire at the Zenor where it returns to the key switch, the new points gapped at the wrong point on the AA unit so about a .002 gap where it needed a .015, Static timed light timed. He never knew about the timing tool... frozen cam adjuster... No drill had ever been run through the idle jet..., the float was set so it hit the carb body and never sealed..., It always leaked he said.
Adjust the brakes and the tire on the rim after a ride or two man this thing is quick.
His comment how did you ever learn all this stuff I don't think I would have ever got it running on my own. My answer :my Dad bought the three boys a broken 50cc Suz when I was the oldest boy at ten and dared us to get it running... The rest just makes you a bit cryptic : "Well I just bought a new part and it doesn't work" I sure would like all those nasty old parts on all those old shelves. Now theres a 1979 750 out in the shop needed the front end sorted yea right... it needs all new wheel bearings and brakes and I still have to make it run on the old Mark two's a five hour job just got to be sixteen hours and may not run this year for lack of funds I am told so I get a little testy sorry...

The Unapproachable Norton Commando

At the end of 1967 the Norton Commando was announced.

The Norton Commando was greeted with a certain amount of scepticism because on first sight the commando appeared to comprise of the old Norton Dominator twin cylinder engine mounted at an inclined angle in a set of new cylinder parts.

It was not realized that the new Norton Commando Isolastic method of engine suspension damped out all engine vibration and produced a machine which had uncanny smoothness for a vertical twin. In due course the critics were silenced and the Norton Commando had the distinction of being regarded as the first of todays so called superbikes. There can be little doubt that the original design concept of the Norton Commando has proved correct, since comparatively few modifications of any real consequence have been made since production commenced during 1968.

Now nearly 40 years later Norton Commando riders like us are a breed of our own, and as far as we are concerned its still more fun to go for a blat on the old Norton Commando, and fast. As a Norton Commando owner and enthusiast, my goal here is to promote and give credit to those who keep the Norton name going.

It is more deserving to give credit to the Commando itself, for after all these years it continues to be respected. The original Commando designers like John Favill are those who deserve the credit for developing this incredible motorcycle.

The Norton Commando Roadster and Interstate of the late seventies, never died. Although the Norton Villiers factory dispersed the tradition lived on. Today Kenny Dreer in the USA is developing the new 952 CC Norton. What a great looking bike this is, and its engineering is still based on the original layout. It will be interesting to see how the new 952CC Norton does in todays tough motorcycle market. One thing is for sure, I would own one if I could afford it.
