Just picked up my first 2 stroke yesterday, a 2001 RM125. Doesnt have a motor on it but i only paid $250 for it. My first question is what other years will fit on the bike? Can i use a motor from a 2000 or a 2002? Next question is where can i get one. I found a couple on ebay but they want ridiculous amounts of $$$ for them. Even if it needs a top and bottom end rebuild, im looking for something that has it all there that i can pick up cheap.
