I bought a 2005 blaster roller the other day, complete with hydraulic brakes, all there and very clean. I have a few options for the motor and one I think everyone will vote for. Here are the possible motors.
- Stroked big bore blaster, ported.
- yz125
- YZ250!!
I'm at the same spot with all these motors, they all need to be rebuilt. I understand the work that will be needed to put in the yz motors. I have ridden a few bikes with 40-50hp and I want that kind of power in the blaster. Leave your opinions, thanks!
