yamaha blaster 240 questions

[schacknuts]

does any body know if the vitos 240 cylinder and head kit are good out of the box or do they need to b ported and head work done

[Jason Hall]

I would say they might rip, from what I've heard the port design is different & your horsepower is almost double. I would fix your rear brakes if they don't work, & think of how you can keep from getting wheelied rite off the back. The cylinder kit probly comes ported or unported depending on what you want.

Yes, it is ready to go out of the box. They do all the port work before hand.
