The pics seem to magnify the problem. Maybe I just need my eyes tested but they don't look that bad in real life!!

They don't appear to have a nice smooth surface to me even if the problem is magnified by the photograph.

If they were mine, I'd get them done, or at the very least get an opinion of someone suitably qualified. The stellite tips are of course very hard, and if the surface is abrasive and not smooth, you will probably end up wearing the cam lobes off quite quickly. If the engine is down, is there any point in putting it back together without getting the followers checked out?

Perhaps the cam-surface could be carefully hand-lapped on a flat plate with some valve grinding compound or other suitable material?

I think that I am just going to bite the bullet and get them done professionally. RGM seem to have the best price at £40 for the four of them. I will get them sent off tomorrow and Roger at RGM says it will take about a week.

There goes a chunk of the money I had put to one side for a Pazon ignition system!!!!

Thanks to everyone for their advice. It has been appreciated.

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.
