I’ve had my 1957 Model 88 for a couple of years. It’s in great condition but has an iron head stamped T2140. I’ve fitted the correct plugs NGKB6HS and it runs well, although perhaps a bit of pinking when opening the throttle hard.

Hi all,

I am having problems fixing / securing the battery in place on a 1960 600cc 99 dominator which has been converted to 12v.

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!
