Hi John

Did you ever solve the kick-back problems? I having them too you see and it really feels like the bike will low-side in every corner when the kick-back comes.
 Is it because it's running too lean or does it have a leak?

John:
SuperMotoKX,

I haven't had the time to thoroughly investigate what the cause of the problem is. I checked out the engine and there is no obvious sign of leaks. But the plan is to break the engine this winter - if I have the time... The thing is, I am kind of busy. Wife, kids work and what not? I just wish I was single sometimes and could use all my spare time to do whatever I want to do.

supermotokx:
Are we the only two kx5 riders in this forum that are having these problems? Anyone else?
 I talked to a Kawa mechanic today and he suggested the ignition timing. But in the end I guess I gotta do what you do: Complete engine service this winther - bugger.

John:
Yes, I have been thinking about the ignition. I figure it's either an ignition or carburetor related problem. I have checked the top-end. Could it be inherited by design? But I guess more people should have the same problem?

Checked the engine outside for leaks and the tranny for compression but I don't think it leaks. I am reluctant to break the engine. If I don't have to - I wont.

I have tweaked the timing some (not really much) - no change. Maybe a different spark plug? Haven't done that yet.

Well, I know there are others who have the same problem. Talked to a Kawasaki mechanic who rides a 500 motard. He's got the same problem - but he doesn't care. He said it is inherited by the big stoke. He was actually the guy who told me that the engine doesn't get enough fuel. Tried with the choke on and the problem disappears - but then aging - that doesn't prove much does it?
