    Hahaha yeah I’ve got a need for more power, I’d love to turn the one on the left into a methanol motor but the upkeep is more than I want to deal with at the moment. The races were fun, hope they have them again next year I’ll be ready with a street tire on the rear

    Sort of big updates lately. Ended up yanking my block out of my bike to do a refresh, hone, rings and put a Star crank in it. One build turned into two today. The two stars I picked up ended up both having VKE rods and billet forged pistons (score!). So since my vke trackmaster block (on the...

    71 Rupp Spitfire

    Parts are on the way! Honed the cylinder and cleaned it up, it’ll get new rings and a fresh set of rod bearings. Pulled a reground Star cam out of the donor motor and may use it. Looks like it was lightened and ground for more lift, I’ll have to measure it up to compare to my stock Star cam...

    Gomas Minibike Massacre #10 - West Wareham, MA. June 26, 2021

    I'm pretty positive it was only one straight up dirtbike chassis. There were two custom rigs and then some older Minis with bigger wheels.

    Gomas Minibike Massacre #10 - West Wareham, MA. June 26, 2021

    I believe there was only one dirtbike chassis rider and he lost his oil in the final iirc.

    Should I put a Tecumseh hm80 instead of the predator motor

    Put the Flathead in it! To add to what the others are saying, yes find an HM80 with a straight shaft. Not a tapered shaft.
