Maintenance & Technical > KX500 Original
Removed Top End (PICS)
95formula847:
I removed the top end of my 91 KX500 after i was getting warm compressions of 75psi. Here are pics of what it all looks like. let me know what you guys think.
None of this has been cleaned up. Everything is in the same condition as when i first pulled it off. The piston looks very clean to me. Is this from running lean? The plug chart tells me my plug reads rich running. Also could the 75 psi of compression cause the bike not to idle? I tried two different compression testers and got the same results. One of which is calibrated every month at the aircraft maintenance shop i work at.
Also are these bikes sleeved from the factory? Because my jug looks sleeved. There are a few grooves in the cylinder walls so if it is in fact sleeved... is the fix just to bore it alittle and run a slightly oversized piston. I looked the part number on the piston up and found it was a standard sized wiseco pro lite. It seams to be in ok shape but i will buy a piston kit none the less. The rings were very loose and could be removed easily with one finger from the piston. Thanks

2 year ago a got bad set of rings that didn't seal, low compression. installed new rings and then i had normal compression.
I would install rings into bore and check ring end gap and see what kind of tension you have. That sleeve looks very glossy.

no there not sleeved from the factory ,,,that cylinder is sleeved..how much water did you burn that will make the parts look clean like the that chamber does may be a leaking fiber head gasket just one possabilty

in 16-18 hours of riding i didnt burn even a drop of coolant. My radiator was filled to the brim the day i bought the bike with clean green coolant. Everytime i rode i checked it and it was filled to the brim.... nice a green colored still. Im 100% sure it didnt burn any coolant.
stewart:
thats good you checked it i have seen coolant do that
