02 KX500

[The Flyin Hawaiian]

Well I got my KX500 this past sunday. Its an 02 that is set up for woods riding. I traded my future brother inlaw my 92 DR435S for it, even up. He needed a commuter bike to get back and forth to work on. The 500 had seized and then broke free. I pulled the pipe for a quick look and I think I can get away with a piston and rings and a cleaning of the cylinder. Any suggestions as to what I can use to remove the aluminum that is smeared on the cylinder walls? I have heard of muratic acid but have never tried it. Its also registered and tagged. It may see some street use after its sorted out. Maybe a dualsport kit is in its future!

the cyl. is coated but the stock coating comes off . you could send it to max power for thier chrome coating and it will last  a lot longer than the stock . if your going to put in a new piston you might as well spend a little more and do it right . you can take the alum out of the cyl. with scotchbrite ( green ) or 600 grit emery cloth. read on here about stewarts pistons he sells . make more power and last  longer than stock ( don't use stock) .good luck

I should have said that it was replated shortly before the siezure and wasnt ridden much. Im going to tear it apart in a few weeks, Im in the middle of some home renovations at the moment, and see whats up.

Comgrats on the swap. Even with the tag ,you run that  down 206 you'll get to know everyone at the Redlion barracks by first name!

Flyin,
  Congrats on the 500.  I have used the green scotchbrite with good results.  Then give it a nice light crosshatch with some 400 emory by hand.  May not be high tech but it has always worked for me. Cam.
