is there any engines that could fit in a blaster and make it fly

 

on u tube i was watching this dude ride a blaster and he put a yz400 motor on it and it flew

 

If your blaster motor is still healthy they respond well to upgrades. A pipe,reeds, a reed spacer ,bigger carb. Check out Trenga Racing they have a lot of blaster parts. I think it would be cheaper than a different motor,plus the headaches of a motor swap.
