[QUOTE="Lorin, post: 703678, member: 16153"] I had Noleen do the head mod on my 92 wr 500 for $80. Consisted of a 2 angle squish (13 & 35), with 20 thousands off of the head. They said it added a total of 2.4 ccs to the head volume. It did help with the pinging on the motor. As to jetting, mine ended up with a 430 main jet, 45 pilot, and the 6f16 needle in the 2nd clip. I later put a 39.5 PWK keihin on the bike. I'm suprised that you can run a 35 pilot jet on that bike. I thought mine was jetted pretty sharp with a 42 (summer-time). [/QUOTE]
