2004 wr 450 I do not like the power with the stock cam, the yz camshaft is too powerful for my limited riding capabilties and estart issues. I am assuming the only cams available are stock yz and hotcams which I tend to read as yz timing with the auto decompresion set up for estart.
the question I ponder is if I buy the hotcam and a high compression piston and then space the jug up to lower the compresion back dow to say 10 or 11 to 1 . hopefully advancing the cams a smidgeon buy pulling the timing chain tighter. I am a very strong class b fleet mechanic but i do not build race engines the tools and work should not be a problem the lack of knowledge and direction is. my mind is telling me that lowering the compresion should soften the hit, advancing the exhaust bleeds off combustion pressure to soften the hit and then tryng to retard the intake cam lessening(?) the overlap should tame the feel of the engine to a lower rpm freindly zone..
barage of question time is my thinking mechanically correct? at what point can I lower the compresion, at what point does the intake cam being retarded at closing time does it wreak havoc with the combstion stroke starting. everybody wants to build a more powerfull bike so it is kind of hard to find info to mellow one out. Is there a custom cam grinder that could possibly grind down the cams by my verbal wants that you would trust?
Thank you in advance
