Hello all i am looking at getting an 04 Dvx in the crate and i have read a few posts on this forum and others that are saying the timing chains in the Kawasukats have been known to stretch. I was just curious if this really is a very common problem for these bikes and if so.....how long does it take for this stretching to take place..ie, in the first year or longer?

 

I have an '04 KFX, no problems thus far. The timing chain does have an adjustable tensioner btw.

It will take a long while to stretch a stock chain unless you are running big cams. I'm sure anyone you've talked to that had issues were doing just that. In the case of larger cams, then I would worry and upgrade to a DID 3/4 or 4/5

For stock, I wouldn't worry at all.

 

I replaced mine last summer. It still had 3 clicks left on the adjuster. I also have hotcams wich weigh more then stock and stiffer valvesprings.

 

well I went 2 and 1/2 years before my timing chain went.
the tensioner had no adjustment left on it
I'm in the process of changing it now as soon as the rest of the motor parts arive
