Just installed a single 34mm Mikuni with the main fuel line running from the main petcock (on the rt side) under the carb then up and around to the nipple on the side of the carb. In my driveway it will die out from what appears to be a lack of fuel. There is an air bubble in fuel line at the bend coming into the carb which looks to the culprit. Problem is that routing the line over the intake manifold creates a tight bend coming out of the main petcock. The length of the petcock and the location of the nipple on the carb makes it tough to route the lines without bends. What's next? Maybe using the left petcock as the main will help, hmm didn't try that, but would the right be less reliable as a reserve?

On the plus side the idle is smooth and steady and throttle pull is now a 2 finger affair. Cool

Thanks,
George K.

George K., Stan at Rocky Point has 90 degree fittings in s.s. for this. You run each fitting pointed to the mittle to a brass T fitting then out of that to an inline filter than to the carb. I use saftey wire dobble wrapped for clamps. norbsa http://www.rockypointcycle.com/

Did the same thing, ordered up the 90 degree fittings and the fuel lines run much better.

Old Britts also sells ready to go fuel lines if'n you want to go that route.

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.
