Yamaha effin stole the raptor 660 motor from effin Mz!

 

I thought Yamaha did that engine for the MZ? (your talking about a Euro motorcycle right?) I have the "Dirt Bike" on that and remember reading about it. Might have to did it out.

 

Man, im hearin both things so i dunno what to believe...i put this in the wrong one tho...i wanted to put it in the yamaha forum.But i wanna know how they got that thing up to 50 hp in stock form......ughh...its not fair....
