    Rebuilding my 02 blaster I just picked up. Needing some opinions on my motor build. I was looking at just upgrading the bottom end with a 3mm stroker kit and leaving the top end stock, since it’s been so reliable. Does anyone have the stroker and big bore kit installed? And how does it run? Or if you just have one or the other installed? Any input is appreciated. Thanks

    I’ll explain my build best I can.

    My son bought the blaster for $100. Little repair work and it was running. Installed Fat Bastard pipe and jetted it. He took it out on the ice and cold seized it, four corner seize. After it was bored I decided to port it.
    Fast forward a year or so and the balance shaft had catastrophic Failure. Seeing that I had to split the cases I figured it was a good time to replace the crank.
    Because I know someone at Vito’s I get parts at dealer’s cost, though I’d get a stroker no matter what.
    I used used the spacer which raised the exhaust even more.

    Couple more things. I didn’t use a degree wheel or measure anything. My son thought it was to “pesky” with the stock crank :eek: it might be a little bit more with the 3mil

    What exactly is your end goal?
    Are you looking for more power? Then have your cylinder trail ported and head mod done
    And you will have a big increase in power.
    Still reliable. And cost about as much as the +3 crank. But with alot bigger power gain.
    Is the stock crank bad?
    I run the 240 and +3 .but it's ported so it runs strong.
    Un ported it's not that impressive.
    If you choose the +3 and porting. They can port the cylinder for the +3 crank so you don't have to run the spacer plate

    Yeah I definitely need more power. Vitos has a 240 3mm stroker kit I was looking into. I know the heads aren’t very smooth flowing, so makes sense. Thanks for your input.

    If you got the $ get it and have it trail ported
    For great overall performance
    Or drag port (drag only)
