Re: stock puch cylinder porting gains

smell my finger /

I opened up the exhaust to match the pipe, and polished it, did the same with the intake. didn't mess with the timing. I only polished the transfer ports. I also polished the piston crown, and the head down working all the way to 1000 grit. I'm hitting 37mph, (cyclometer). I've also side gaped my plug, and I'm noticing a bit more torque. Still using the 14mm bing.
