anyone know how hard this would be to do and how much power it would have in the light blaster frame?

 

That engine would destroy the frame in no time at all!

If I was you and I had a blaster with that many mods I would just keep updatin the blaster and not worry about it.

 

True that motor will rattle the balster apart. And you better think about hydrolic brakes. You should see what the cr500 motor does to a 250r frame. Talk about stress cracks..

 

I'd go with a 250 rather than the 500. Still alot of power but not too much!

 

Jeez man, I woudlnt bother, do you have any idea how to put the liquid cooling from the 250r motor on to your frame and have it look good? why not go pick up a old air cooled YZ465 Open class MXer motor, its air cooled and it would haul. stick to something air cooled. -Mike
