Sounds like things might benefit from a richer mixture.Try a half a turn on each carb (clockwise), and see what the difference is.

Graham,I watched it, and I thought I heard a few seconds of what sounded like a rotary Norton.

Sounds to me that something is stopping one or both of the dampers from rising properly.Try just unscrewing the damper rods (but don't pull them clear of the carbs) and try to lift the dampers with the rod.Generally speaking, Rotella 40 or equivalent is the right oil for the dashpots.Make sure you h...

You could use the fuel tap set on the "prime" position, a length of hose and a gallon tin to drainmost of the fuel out?Not sure, by the way, what you mean by a bolt on the left hand side of the IP2 tank?

Tig,As far as I remember with the F1, with the ignition on (without the motor running) and the throttle closed, the fuel pump should run continuously. Fuel can be heard sloshing around the "weir" at the rear of the tank. (One of the reasons for this was to prevent the carbs flooding on the...

I think I'm right in saying that Tony Page's Interpol at 480,000 + miles is still on the original rear chain.

I'm with Carole Nash, and pay about £230 for the two rotaries.I'm paying extra for the F1 engined special, but it wouldn't hurt to try Peter james at renewal time.It's just a faff explaining the modifications.

It looks similar to a Classic/Interpol/P52/3 gearbox end cover.It maybe a special of some sort.

Richard,The gaiters should be with you any time now. At least I hope so!I posted them Mon.John.

Steffen,Try Andover Norton, they should have some. They should also have the stainless steel rivets that go with the plate.

I'm not sure that the top photo is actually Peter Kirby.

Why not remove the powder coat and leave it as cast?I removed mine 15years ago. The motor runs cooler and (to me) looks better.

Quite a common fault.It'll more than likely need a new sprag bearing, although it runs in a sleeve (press fitted into the clutch) and sometimes these can wear.Try a replacement bearing first. It fits under a smaller version of the circlip that holds in the diaphragm spring.Easy to replace, and I'm s...

Joe, I note what you say, and fair enough, I was wrong to suggest I received poor service. I was in a bit of a rush in this instance, so next time I order anything, I'll allow a bit more time.Actually, Phil and Nick have always been friendly and courteous whenever I've placed orders in the past.I ca...

Bob,Thanks for that.I do have the original Wust development hardbacked build/parts change/mileage record and rider's notes logbook.I treasure it as you can imagine.John.

Yes, try Andover Norton, but don't hold your breath whilst you wait for the bits to arrive.Poor service.

Bob , thanks for the reply.I've cured the bike, the fire brigade has just left.Joking apart, the commander I'm working on was given to me as a "basket case" to assemble into a running bike- as best I can.A lot of the bike has been damaged at some stage, and it looks like several experts ha...

How old is your radiator?Maybe a good time to have the rad overhauled?Is the fan working ok, and spinning in the right direction? Obvious I know, but it should suck, not blow.Is the impeller sitting close to the pump casting, and are the casting vanes in good nick?Perhaps you have an air lock somewh...

Bob, I've often wondered what Doug's modification involved, mainly because it's fitted to my old air-cooled- the "Wust". Remember that?Well, it's still running beautifully with about 110K covered and I still love it to bits.You are dead right of course, the neutral finding is always perfec...

I can attest to Bob's riding and technical skill during my time at Norton, and rode with him quite a few times.I used to watch aghast (and of course with admiration) at some of his antics, and usually got the impression that he was hardly trying.Three of us were out on Interpols on one ride, somewhe...

It might be worth considering returning the bike to original spec, if you do really want to sell it.

Yes Don Woodward was a brilliant and thoroughly nice bloke to know.I got to know Don in the late 80's during my time at Shenstone. He certainly did a lot of work for Norton, including the original "Aurora" ( where did that name come from? ) tanks of the late 70's rotaries, Classic , FI , P...

That looks quite normal to me and there isn't much you can do about it.If the wear on the edge is particularly bad ( where the small part of the seal rubs ) rebuild the engine with the apex seals upside down.Atb.

Roberto, I seem to remember Norton playing with ( I think ) Carbon fibre one piece seals, although I'm not sure if they were ever used.Richard, any ideas?

Hello Blair,Carbon on the rotors is nothing to worry about, unless it's black and oily.Check that it's not over oiling ( which isn't detrimental to the engine- unless you ride it slow ) if it worries you.Other than that, give it a bit of "Italian tuning"

If it is very reluctant to fire it might be due to fuel having turned into toffee in the carb float bowls.You might just be lucky though.

How is it running now?From the way you describe the problem, it sounds almost as though you might have a blocked fuel filter, and / or failing ignition box.Sudden clouds of smoke can indicate a sudden unblocking of the frame drain into the left carb.For it to happen after you made your mod maybe coi...

Hello Richard,Have sent you a PM re your discs.John.

Try Norman Hyde of Warwick who supplies Ikon suspension units and springs.The Ikon springs will fit the koni units, and from memory a 213 spring is the next stronger spring up from the std P52/P53 spring. If you want to go stronger, try 222 springs.ATB.

Yes, as I remember the air-cooled bikes had a reputation for running rather warm. In fact they were affectionately known as "mobile furnaces".I recall an Ip2 coming in from Notts police (I think) that was claimed to have reached near to 300C! It had run that hot that the air-box had melted...
