Hey evryone and, proud blaster owners. First timer on here. Just a lil bout me, I own a 1988 Yamaha Blaster and have ridin it for awhile now. Rebuilt the top end too many times. since then have done a motor swap... don't worry though the new engine is still a Yamaha 2 stroke. It came from a 1976 yamaha 2 stroke 500cc dirt bike. Need some help though on figuring out what kind of motor it really is. I'll post my problem in another decussion though. You're probably wondering why the motor swap. With my size and weight the Blaster fits me like a glove it just needed a kick in the a$$, LatersI:I
