    .80 over is the highest you could safely go, but it isn't too safe if you ask anyone out there. My buddy has a 280 kit on his 97 blaster.

    if you want more cc get a bigger bike.

    if you want more power get a stroker crank if you havent alredy got one, that will keep the number even.

    There is no such thing as a 310 kit for a blaster.
    If you have a 240 kit you can get a longer stroke crank +3 with out trenching the case anything over you wil have to have the case trenched.
    If you want more power invest in a good port job. Go over to everything2stroke.com and look up eveiltwin he does the best work.
    Finally got a 450r!

    Definately agree on that. Get alot of power for a bit of cash!
    Just talk to Evitwin, he's a good builder and can give you good performance tips!
