Raise the subject of Armours at any VMCC then you'll get a 90% negative response. In fairness, the other 10% speak highly of them.
I've tried lots of places over the years and nowadays never go anywhere else but Aldens, near Market Rasen in Lincolnshire. They only work in stainless and if they haven't made any for your model then they would need either a pattern or your bike, but Dennis - who owns the company - does all the manufacturing himself and he's passionate about quality and good fit. tehy're now the recommended supplier for several vintage clubs. I've no connection with them at all, other than as a very satisfied customer.

A big thanks for all the advice I've received. Moss Engineering say they've relined these bores in the past and metal thickness isn't a problem. So the barrel is currently winging its way to them for restoration.

I  can't send any pics because I put it all back together in the hope that I'd get away with it! As far as we can tell the bike was taken off the road in 1928 and hasn't been used since. The rear piston had seized in the bore just below TDC. The bore became corroded but the piston remained incredibly pristine. There are no tramlines - just a pitted area over an area of the bore. The result is that a nice compression starts to build up until the piston reaches the damaged area - at which point virtually all compression is lost, just when it's needed most. The engine will run but it runs more like a badly out of balance single than a V twin. I'll give Moss engineering a ring tomorrow - thanks for mentioning them, It was Cameron Racing who told me that JAP sidevalves could not have liners fitted but since then several people in both the New Imperial Association and in the VMCC have told me that their advice isn't always either unbiased or of the best!
Many thanks,
Pete

Thanks for your speedy reply. It's a 1923 KT series, so a sidevalve with a blind bore. It's on standard sized iron pistons with three (I think) rings above the gudgeon pin and one in the skirt. The piston is absolutely perfect, with not a mark on it. I'd heard that Bedford pistons would fit but the vintage piston co says that they will fit the post 1926 models, not these earlier ones.

I've nearly finished restoring a 1923 New Imp powered by a JAP V Twin. One cylinder is perfect but the other has a damaged bore. I've tried everywhere I can think of to find an oversized piston so that I can give it a rebore but none exist anywhere. I've tried also to find non-JAP pistons that would fit but I've drawn a blank there too.  I've been told by a company specialising in JAP's that the casting in the cylinder isn't strong enough to have a lining fitted.
 So... what are my alternatives? I guess I could have an oversized piston made, or I could have the bore ground out and then hard-chromed back to size. Has anyone out there overcome similar problems? All suggestions welcome.
Pete
