Well, I took the engine out of the blaster today. Measured the new engine, it is 20x20x20... Pretty big. I'm going to have to extend the frame...
Luckily, the blaster engine isn't going to waste... Its going on my 03 crf150f. It actually doesnt look like we have to do too much fabricating to the frame, but it will need cut because of the way the blaster pipe is shaped... I was going to use my old pipe from my yz250, but decided against it.
