biggest bolt on big bore?

[mhewitt]

what is the biggest "true" bolt-on big bore it for the 06-09 trx450er? i see wiseco makes a 500cc kit but only sends the sleeve and u have to have it done by a shop, im talkin a kit where i can just bolt the cylinder up with no mods to the caseing or any of that i wanna bolt it on and ride

Ice Cube is prob the biggest bolt on but the cylinder works is prob the most bang for the buck i wouldnt go more than 97mm with your stock stroke.
