Back in 96 I recall using Kawasaki fibers and steels from which years of kx I can't remember....I think that from 89 to 99 the plates were all the same tho....again not to sound bias but you can't go wrong with pro x brand clutch plates. As for oil.....I ... more »

A few suggestions i can offer on that motorcycle, if the cylinder is still plated (but possibly a bit worn)go with the fractional larger sized pro x piston. While you have the cases split for crank removal take a very good look over all the tranny gears. ... more »

When all the clutch plates are removed can you spin the inner hub freely? In neutral obviously.

I would recommend checking your VIN. It looks to me like you have an RMX. The RM stator didn't look like the one on your motor cycle. I may be wrong but after 92 the RM has kiehin carbs not the mikuni....

On the parts diagram, that piece is #8 on the cylinder head page.It is used to seal the spark plug between the head itself and the valve cover. Im guessing you may not have the cam timing correct and the piston is contacting the valves.

With all those pics I only see 2 RC related products.... That's gotta be hard to do.

Added reply in a thread please explain the theory here 8/28/2014 7:49 AM

On this particular engine design (04 yz250) a reduced comp ratio and lower squish velocity might have actually helped. The "ported" cylinder has the transfer ports raised and roof angle corrected in an attempt to change the mid-top power.

Oh you betchya it was running , fairly normal really albeit pretty rich. This mod was done by a "tuning" shop that had a "ported" cylinder as a pakage. Ive seen many different examples of deflection of the gases in the head none of which could be quantified ... more »
