Hello All,
I have a question about my KTM. It's a 1984 495 MX. However, going by the engine number and the appearance of the lower barrel fins, it is a 1983 engine with a low compression head. I am wondering if putting a high compression head on would make much difference. Thing is, I am running the bike without a head gasket, as I can't find one for it. Would this take the compression up by much? There's one more thing - it looks like a 1984 expansion pipe and aluminium tailpipe that's on it. Not sure if the pipes are much different or not?
Thanks.
