My friend just bought a 02 KFX400 ( its a Z400 with green fenders ).

The Quad is making clacking(sp?) noise when running.

Seems like we need to set the valves, anyone knows how much we need to tighten them? Or maybe there's other stuff we should check first, like the timing chain tension?

Thanks for help,

Alain

 

ud prolly have to call kawi dealer or sumthin to find out, i have an 03 but like it makes a rattlin noise but when i pull in clutch, but im pretty sure its just flywheel. but yeah def. call kawi dealer.

 

As far as I know, you can't adjust the valves by tightening them. You need to check the clearance at the cam lobe and you adjust it by putting in spacers.

Yea u can but a set its kinda like pocket knives but they come in different thickness and you slide it in theere and tighten it down so that the spacer can move out with a little rubbing

 

feeler gauge

 

Isn't that what I said?

Bill

 

Yea basically lol

 

Thanks for reply, we're gonna open the motor today and have a look at the timing chain, we'll see if its stretched

 

Yeap the timing chain is streched, we're gonna change it next week.

Now my damn Raptor started leaking lots of oil around the drive chain sproket shaft

Im gonna have to change the seal next week. Damn Yammies
