I already had the lighting coil and flywheel from 4hp Tecumseh. Decided to put a new headgasket on it , but thought...

    cutting seats for bigger valve question

    I never thought of this when I had my intake seat cut to go to a 27mm from a 25. seeing that you cut the seat to go bigger do you need to have the bowl cut as well to actually gain from it all or did I gain anything just cutting the valve seat to go to 27mm. with the bowl being the same size I...

    Engine dimension chart?

    OK so I'm new here and so I hopefully am not asking something that's been made sticky but missed by me: Is there any engine dimensions thread listed that I'm missing? I know most mini bikes will take 5 HP Briggs and Tecs all day long, but what about 7, 8, 10 HP etc? Or should I keep rooting...

    Bigger wheels and/or tires?

    Are bigger wheels and/or tires available for the Baja Warrior? Can 20x7.00-8 tires be used? Looking for the widest, largest diameters I can use on the Baja. Failing that, looking for the widest, largest diameter wheels I can get for/use on it. TIA

    DB30 Wheel Bearings

    Has anybody had their wheel bearings fail or wear out ??? It seems like they would be susceptible to failure especially with a bigger engine swap. Can you get American made bearings to replace them ??? Anybody got any part numbers for that ???

    carb size

    is a 19mm promax carb too big or not big enough for a (modified)hf212 and no one replied when i asked if buying a ported head with bigger valves is better than buying big valves and installing them and doing my own port work (hemi engine)

    Gusset bushing or bigger bolt?

    So I got the Trail Blzer up and running this past weekend. I call it, The Speedy Turtle. I mean the picture says why. I made the seat and got a little crazy. It is almost a bench seat for a mini! Anyway, the gusset is missing the bushing. It is 3/4" ID . I currently have a 5/8" bolt going...

    Bigger carb for governed GX390?

    Is there any thing to gain by swapping to a bigger carb, on a 4000RPM 390, in a heavy kart? I'm milling the head .100, have done a decent port job, good seat work. Maybe 1.2-1.3 rockers? Advance the cam a little? 6-10 degrees more timing?
