I can't... Even down hill, you would be running something like 20,000 RPMs unless you have gears, you'd blow up the engine. |

maybe he was going 68mph down a very steep hill with the clutch pulled in,but that would have nothing to do with how fast a bike with engine goes.
I can go 35mph down a flat road with a 48cc and 44t sprocket,but i dont need to go any faster than that. |

Raw 80 (66cc) motor, Schwinn Delmar, 44t sprocket, calibrated digital speedometer:
30 mph on flat, smooth roads
34.9 mph with a good tailwind/and or slight downhill
Cruises best at 25 mph. |

black stallion engine kit,ported head,notched piston,ported intake and exaust and a little tinkering with carb aswell as a nasty leak from the crank seal behind the magneto it looses so much pressure the engine stalls as soon as the clutch is disengaged, any ways 38.3 mph on a old heavy bike with me 205lbs and the current motor issues  | | Thread Tools | | | | Display Modes |  Linear Mode |
