Hello all, just learned of this forum. I am very impressed will all the Blaster lovers here and the mature infomation exchange. Very cool sight. Here's a Stk stroke/cylinder blaster we just started working on. Cylinder is 68mm bore. 39pwk Carb, custom intake, v-force 3 reed, head reconfigured/o-ringed, custom race pipe. This setup is for pump/race gas mix.
