I destroyed 2 of my gears in my transmission. I'm wanting to know if there are heavy duty gears that I can get, or if there are any gears out there that are compatible with my blaster. Here's what I have done so far but I'm going to put a 240 big bore kit on it with a 3 mill stroker crank. 29mm pwk, dirt digger clutch, Wiseco clutch basket head mod, my current piston and cylinder are 66.5mm.. thanks.
