Thats what i plan on doing. KLX is realiable as hell. Valves being too tight are the only reason i couldnt get it to start.

Glad i got the shim kit.


Its really not hard to do at all. Im pretty fast at it now.

 

Does anyone have a theory why it's the intake valves that tighten up?

I'm working on a non-running 2003 Suzuki Carry (660cc) truck for the second time right now. A year ago I found all six intakes too tight to get a .002 gauge under, reshimmed it (to the thinnest shim they make) and got .009 clearance. 1000 miles later its back w/ no intake clearance again. Exhaust are fine both times. I'm working on pulling the head right now.

Thanks for the reminder!! Checked mine tonight, one intake and one exhaust were out of spec. Luckily my buddy had that same Hotcams kit EMS posted above and got it shimmed nice. Started it up and noticed difference immediately. It's funny how you don't notice the gradual performance decrease, but when it all gets fixed at once it's like a light switch was flipped.. You see the light! hahaa

Thanks again for the reminder

 

Exactly!! I took mine for a ride for the first time tonight after doing the valves and rejetting the carb leaner, and changing the needle jet holder to a 300, and it goes way better now. I did not do the valves after doing the 351 and I took it out for a couple of full throttle runs. I think I hit the jetting spot on! I am using stock cogs, and tried a few roll on wheelies standing up and nearly went over backwards from a nearly dead stop in second. I think I have hit the g spot.
