I have an 05 kfx 700 that doesn't hit the top end all the way like four hundred rpm shy.It is also slower to rev up than it should be.This is in comparison to three other 700's .I'm at the point of thinking something mechanical in the engine is wrong in the way of timing.The bike has less than forty hours on it. I tried richening it up a little bit but it had no effect.I also checked the valves one was a little tight but not bad.If any body has any ideas or suggestions I would greatly appreciate it.

Thanks Blake

I'm surprised I haven't heard back from anyone with some idea's I talked to a knowledgeable guy at a dealer today all he can say is that the bike are really bullet proof and don't usually have problems.He thinks it's carboration and not in the engine it's a good possibility but what else can you inspect beside the ports and needles and jets?
