    Hemi Predator 212cc Upgrades

    Somebody asked me for a shopping list of parts and work to do on a mild Hemi Predator 212 Build. I figured why do this through PM's. Let everybody see. I don't claim to be an expert. My best advice is to call ARC or Email NR Racing for expert advice. However; this thread is yours, should...

    Flywheel Failures

    On one of the FB groups I belong to the Billet Flywheel question came up. It was something like if I use a MOD2 cam, do I need to upgrade the flywheel. And reply after reply said YES. And I wondered how many of those people actually had a flywheel blow up. So I was the A-Hole that said "Prove...

    You Can't Say Bomb on an Airplane

    My buddy asked me to feed and let his dog out while he is away. So I go over there, I rode the minibike for a while, then I take the dog for a walk. I planned on walking up to my work (right across the street from where I live) and using the dog to hit on my co-workers. Well the entire area...

    When does the spark plug spark?

    There is some crude method of determining ignition timing by using the legs of the coils and the edges of the magnet, along with a degree wheel. I mentioned this in the lighting coil thread, but this is a more specific question and hoped it would get a better response if not buried in an old...

    Camshaft Timing Predator / Honda / Clone

    Anybody ever try retarding a stock camshaft by 1 Tooth? I just counted 48 teeth on my Predator camshaft. 360 degrees / 48 Teeth = 7.5 degrees per Tooth. Say you removed the governor, got a billet rod, upgraded the valve springs, advanced the ignition timing... You know, all the things needed...

    Lithium Cycles Super 73 Electric Minibike

    Lithium Cycles Super 73 Electric Motorbike https://www.lithiumcycles.com/ Not sure if anybody shared these yet. I vaguely remember something. I guess they started out trying to make an ebike base off a Taco minibike. Pretty cool idea I might steal. Maybe something like a 36v 750watt 20" x 4"...

    Live Crude Oils

    What an attention grabber, huh. Now that I have you here, I’ve got a puzzle for you. What might cause the oil in my catch can to be nasty, chalky, and milky. But the oil in the crankcase remains a pretty amber color???

    Carb Tuning Pilot Circuit

    This is my first time playing with a motorcycle type carb. It is an OKO 24mm (Keihin PWK knockoff), but this is a generic question about tuning pilot circuits when using high stall clutches. For jetting the idle circuit everybody says to adjust the jets and pilot mixture screw until you have...
