Re: F1 Plenum chamber item 12 on parts list?

Hello Ed,

Item 12 is one of two vacuum take off screw in plugs. They are exactly the same as the ones fitted to the other Norton rotaries.

John.

Re: carbon removal

John,There is no easy way to remove the carbon build up other than lots of elbow grease. It always is a long, filthy, ball aching job.As far as the rotors go though, you could try leaving them submerged in a reasonably strong caustic soda solution.First thing is to remove the bearings by taking out ...

John, the parts book is correct!

Re: allan screws

You are right that the gear cluster was originally Triumph, though I'm not sure if the Norton type clutch was used by Triumph.To my knowledge, Norton used at least four different mainshafts. All had the same clutch.That's discounting the F1 of course.

Re: allan screws

You are right John, putting in new rubbers is far from straightforward.......It's a bit "quart into a pint pot" type of job where the new rubbers seem to be a lot bigger than the old ones.The first one will go in easy and so will the next one. It is fitting the third rubber that is a chall...

A tricky one that John!It might be worth asking Andover Norton the cost of a replacement?What is the condition of the clutch plate grooves?

Re: allan screws

John, I presume you mean the countersunk screws removed with a 3mm key.Give them a tap first with a brass drift and hammer after some heat, then using a centre punch, as far from the centre of each screw as possible, "drift" the screws anticlockwise. That's how I usually get them out.

Re: stators

Commander / F1& F1 Sport generators can be obtained from Graham and I imagine from Yamaha dealers.The generator fitted to the Classic and Interpol is not the same as the one fitted to the above. Try Graham for either.

I'm not sure if any other bikes have the same size spline as the Interpol / Classic, but the Commander / F1 / F1 Sport, have the std 10mm Japanese type spline.The Commander one is interchangeable with the Interpol / Classic type.

Re: Help . My F1 has died...

As the others have said, your engine seems to have "flooded" with fuel.Remove the plugs but before you put some new ones in, leave the bike for a day or so to let the excess fuel evaporateout of the motor.Good luck.

Re: cooling probs.

What is your oil consumption like? Perhaps a bit lean?I've always felt that the air, the air cooled engines take in is somewhat restricted by the closeness of the coil cover, and coils,and two thick filters.I binned one of my filters years ago, and also removed the powder coating from both housings.
