Looking @ buying this blaster from my girlfriends brother. Its in real nice shape, a few upgraded parts including exhaust and nerfs...but the motor is blown. He said the cylinder needs to be bored, and I think he took it to a shop which told him that. I think its been rebuilt a few times, so maybe this time he really mucked it up (obviously doesnt know how to care for a 2stroke). Anyway, if I buy it..whats the best way to go here? I want the most power possible, at a good price. Is there a 230 or 240 kit I can just bolt on in my garage instead of going to a shop and having the stock head bored? I know you can sometimes but a new head with piston/rings and just replace the old head. What would you guys suggest here? Any advice and input would rock! I really want to join the blaster world.
