[QUOTE="skipn8r, post: 1080614, member: 52414"] I don't know about Kawi parts, but Honda heads are only about $55. I can have my head milled locally for $20. So even after milling, I can go back to stock for a total $80 investment. 2 mm seems like a huge amount to mill off a head. I measured my stock squish clearance at 0.060" and it went to 0.070" after a new Wiseco piston. So I had my shop take 0.020" (0.5 mm) to get down to 0.050" squish clearance. I haven't gotten the jetting sorted out, but it feels really good so far. Part of my reason for taking at least a small amount off the head is that I'm at 5,300 ft elevation. I say experiment and go back to a stock head if you don't like it; it's cheaper than experimenting with a reed cage, a pipe or porting. [/QUOTE]
