Default Re: New here, with a DIY Chainsaw Bike

Did some port matching today of the exhaust gasket and DIY header box. It was riding fine, but I figured it was time for me to reclaim a couple mph. The ports are matched as closely now as I could get with a grinder and hand files.

Number one is now faster than she's ever been. I hit 29 mph for a new top speed on it, and acceleration is also improved. There was a healthy wind in my face at the time, too. The flow seems just about perfect.

It'll be hitting 80 (documented) miles sometime this weekend.
