What kind of cams do you have?

Yeah I suppose lots of little things... the good side of it was I finally splashed out on new jets etc for teh carbies... they have around 360,000kms on them...

I dont know what brand the cams are, and there is no name printed or pressed into them.  I worked for a few years with the guy I bought the bike off and he had paid a lot of money to have the engine rebuilt with oversize Wiseco pistons and lumpy cams, if memory serves, I think he may have said they were mild cams.  When that engine burnt a few valves I considered rebuilding it, but every single valve guide needed replacing and all the seats needed re-cutting.  Very expensive option down here is Aussie.  I found a 2nd hand Japanese import motor with supposedly 18,000kms on it, bought that and installed it.

I recently replaced the head gasket and decided to use the cams from the old engine. From basic measurements of the mild cam compared to the stock cam, it seems the profile is skinnier, not taller.
