    I clocked my bike going 27 MPH on a flat surface. All stock. Is this a good speed? How fast can you get yours going?

    27 MPH sounds about right for stock....I've been to 34.4 MPH using a 36T sprocket (6400 RPM....about as high as I want to wind the engine...I will use a smaller sprocket on my next build).

    Going to a smaller sprocket may only net you lower rpm, but no gain in speed.

    Unless you make engine mods....

    Ok, Thanks. Thought I might have been going a bit slow. I feel like I need more speed. Will get into mods later. :)

    en cuba, i've gotten one of my creations up to around 50-60 but that was a very light frame, plastic bottle tank, and a 150CC from a old motorcycle.

    edge Here you go:) Google Bonniville Salt Flats. It's in Utah. Also Speed Records. I'm not sure but I think the two wheel speed record is close to 400 MPH right now (c)

    35mph winding out at wot - pure petrol/oil mix @ 50:1

    32mph cruise at WOT - petrol/oil/nitro mix @50:1 + 50mls per gallon Nitro.

    I havent had the machine wide open on that mixture yet to see top speed.

    These figures with engine fitted with tuned pipe.

    36mph maximum with petrol/oil/nitro mix as above w/o tuned pipe.

    some simple exhaust porting and a 36 t rear sprocket on flat ground running with a 26"x2.125 street tire I can cruise easy @ 32-33-34mph. but my fastest has been 39 mph and I was tucked down on my bike for less wind resistance
