I think the blaster engine will compliment this bike really well. The porting is pretty
simple and it has a wide, linear powerband which should make for an easy riding bike. Power density is relatively low but it should have no problem cruising 70 strapped to a 180lb street bike. It has a 12v 55w output lighting coil which will make wiring super easy.
They also didn't change for the 20 years they were produced so parts are a dime a dozen and they're practically bullet proof
The main mounting point on the blaster engine utilizes the swingarm bolt. The spacer between the bushings on the MB5 swingarm seemed to be pretty close to the same diameter to the blaster swingarm bolt. I figured this would be the easiest way to establish a starting point. I cut the spacer in half and sanded down the OD until it slid easily into the mounting boss. Then it was more or less located in the frame and I just had to get the other mounts figured out.
