there is a guy in my area where i live that does boring, and stuff like that but i would never trust him witha cylinder becuase everything he does only lasts a few weeks and is shot, and plus he charges an arm and a leg, he is not reputable or trustworthy at all.so i cant help ya at all on this one.
my trikes:
1983 honda atc 200x-k&n filter
2002 yamaha raptor 660r, yoshimura slip on, prm grab bars
1978 chevy nova, 454 v8, bds blower, 150hp shot of nitrous, full roll cage, a real power house.
1991 chevy s10 4x4 350v8.
1986 250sx
YES its fast NO you cant ride it.
