First off, I'm not an engine builder, but with the help of a credit card and this forum I put together a +4mil, stock cylinder. The cylinders are not a fresh bore. I bought them with what looks to me like an aggressive drag port and was told for a 4mil. I put new crank with new piston/rings. Checked comp again today with warm engine and got 150/151 psi. Running coolhead with 20cc domes. 34mm mikuni TM's no crossover. Timing plate at +4
Including this weekend, The engine prolly has two tanks of fuel run thru it. 75% drag. It has absolutley no bottom end, but thats prolly the port job and 34mm carbs(I think). It runs very strong at the track. We run about 500ft. After 3 runs, the plugs are loose
This is a totally different bike than what I had with stock crank, so I know I'm making power, plus I'm kicking asses that I couldn't before. When the guy with the can am 1000 got his ass handed to him, I was a happy ole man! Thanks fellows
