93 KX 500 Rebuild
Jeff90lx:
Hey Guys!
So, I'm new to the two stroke world. But I bought a 93 Kx500 a couple months ago and it has been a blast to ride until about 2 weeks ago when it died on me and I couldn't get it started. Anyway after doing some troubleshooting it had about 50 PSI of compression. Not good. So I tore the top end apart and the piston looks terrible. I will take some pictures tonight when I get home but I was wanting to get some opinions on who I should send the cylinder to? I want to get it re-plated and get the intake and exhaust ports reworked (Sharpened) and get the KIPS valve cleaned and reworked also. I'm looking to go with a Wiseco Piston kit. Any advice is appreciated... Thanks Jeff

welcome to the site Jeff.
1st, scratch the idea of Wiseco!....go with a Wossner.
Either PowerSealUSA, or Millenium Tech are the best places to have your jug plated.
Our member Sandblaster may be able to rework the ports.

Has some deep gouging near the exhaust ports, any ideas on what went wrong? Any piston experts out there?

Take foxx's word on the Wiseco. For some reason the wrist pin bearing loves to disintegrate. Happened to me and another few members. Go with wossner. I've had good luck with plain old pro X but I inspect the cylinder frequently as well
