kwakman:
looking good.how did you find the platinum pipe with fmf silencer when engine was stock?thats the combo im using next.did it make good top end power? decent overrev? thanks, k.

Thanks guys.
kwakman, I started with a stock pipe and silencer, but eventually flipped the bike and destroyed the silencer, fender and sub-frame. Picked up the Platinum pipe after reading here on kx riders how well it performed. The FMF silencer was just a simple decision. I didn't like the pc silencer's looks or sound. I felt a noticable increase in power with the new exhaust, and it sounded healthy like I wanted. As far as overrev, I don't think I can give a good report. My 500 seemed to rev about 3/4 as much as my 250, so I had to gear it to be fast. This being my first 500, and every upgrade adding a little power, I really have no base reference. I had a crank issue that probably kept the motor from revving high, which has since been resolved, during the rebuild.
Pro Circuit, V force Reeds, Wiseco, ...ect., everything Stewart has stated as being strong reliable performance upgrades has been just that.
Goat:
Bike looks excellent. I agree with you on the pc vs fmf. I have a pc spark arrestor on one 500 and fmf turbine core on the other 500. I can't confirm performance exactly because of the different engines. Ones an 87 and the other is a 93. I am going to try swapping silencers and see which works better on what bike. I like the sound of fmf though. I'm looking forward to some hill climb videos Hint Hint :D Don't have much for climbing around here unless I go way north. Keep up the good work. Good luck in racing.
