Hi everyone! I recently bought a 1999 kx500 after selling my 86 cr500. I like the k5 alot more all around. I rode it for a week and figured id do a compression check. It read 120psi. So i tore it down the same evening to discover worn plating on the intake side. So i sent the cylinder to powersealusa they done an incredible job, got wiseco top end kit and bearing, cometic gaskets and the oem thicker head gasket. Cleaned all powervalve parts and put it all back together and broke it in. The bike runs better than before but seems like a smoother hit must be the gasket talkin. Only thing is the bike wont idle anymore. I posted a question about it. Kx500 forever!!!
