Biggest Bore?

[raptorrider686]

I bought a Yamaha Blaster with a top end that was fried. Considering its all apart now, whats the biggest bore kit out there? I know there is the Vito's 240 big bore kit which is 73mm bore. But is there anything bigger out there?

the 73mm bore is as big as you can get for the blaster motor. It makes it a 239cc engine with stock stroke. You can always throw in a +3mm crank and make it a 251cc. :devil:
