hi i was wondering if it is possible to stick a 10R motor in an 03 636. if so how much work needs to be done to make it possible?

 

Welcome todd, if you can figure how to run a liter motor in a 200 lb bike frame all the race teams / manufactures' will want you, you will become richer than your wildest dreams and all fine a$$ women will lay at your feet.

Let me know when you get it and we can ride the lightning together.

JK bro, if you want a liter bike go buy the 10R.

 

I don't know if that can be bolted in but It's possible with modifications. Also, the frame may not be able to handle the stress from all the extra horsepower. The 600/ 636 racebikes put out around 130-135 HP with lots of mods & race gas.
