I'll prob regret it but I decided to get rid of my honda crx. It's been a work in progress for too many years and I've lost interest in it. Just so happens that I made a deal to trade it for a pair of blasters. One was just rebuilt with a 240 big bore kit and the other one has a bike engine on it? He said it's a yamaha 2 stroke but has 10 more horsepower than the stock blaster engine and it's 5 speed. It's bored over and both have wiseco pistons and the one with the big bore kit has an fmf powercore 2 exhaust.
