Hi everyone, I'm getting ready to put a 65cc Airsal kit on my za50, I'm aiming for a low-mid rpm setup that will reliably go 40-45 with "stock-like" reliability. I THINK I have the timing/jetting "thing" down now but don't really have the tools for measuring/reaming of the wrist-pin bushing. Or should I (can I get away with) just running an out-of-the-box replacement since I'm basically building a "thumper" ?
I have 20-36 gearing, 15mm Bing, and (currently) a Circuit pipe.
Thanks in advance.
