Heavy Twins

Does anybody have any good information regarding the seats that go with the small slimline tanks on US market Atlas', ES2s, and, (dare i say it) Manxmans etc?

I have a SLS brake on two bikes and a TLS on another , I am often tinkering and usually manage to keep the efficiency up . However the TLS has had new "superior" linings fitted and will lock up on first application but refuse to do much else.

Hi guys... My 650SS restoration is progressing apace. I had the bare crankcase and cylinder head from the original matching numbers engine. The other major engine parts are coming from a donor engine that had been "tuned for racing".

My 1954 88 has a fairly bad oil leak from the dynamo clamp stud area. I have replaced the base gasket and cannot see any obvious cause of the leak which is still present.

I have replaced a dud drive box on the 99 back wheel with a NOC one and the chrono speedo now reads very about half speed. Is there a range of these gearboxes, and if so what should I look for?

Does anyone know if ally petrol tanks are affected by ethanol, Please?

Apologies if this post has already gone on forum but can't find it - has anyone experience of gearbox rebuild kits available from Andover Norton - all the kits available seem to have gone the way of roller bearing on layshaft - Mick Hemmings thoug

Does anybody know anything about whether machining the early AMC mainshaft to accept a circlip has ever been "a thing".

If anybody has a Commando mainshaft to hand, and a vernier, even better!

Did Atlas/N15 etc have 2 different length inlet manifolds? as I have a set of manifolds that I got years ago that are 1/2 an inch long with an ID of 28mm possibly concentric?
