    Yes indeedy with that thing. And no it had a 26t sprocket when it reached that speed. My brother changed it to a 44t because he has some weight on him.

    46.5 mph. Stock? With that padlock and chain?:eek:

    I have some doubts. Perfectly flat, with no tail wind and floppy chain?

    Possible, but doubtful. Not many see that speed, even with a pipe and decent mods.

    Yes... 26t sprocket at 5700rpms would hit that speed.

    Lots of pedaling to take of, eh?

    Seems much more practical with the 44t sprocket.

    It was a perfect night with hardly no wind, The gearing with the motor was change by previous owner, it was on a crappy bike when i brought it off him, so i popped in on a racer frame. probably the reason why it hit that speed. I did peddle at the start but not much.

    I sold it to my brother for $100AU. He change it to another bike because he thought it was a death trap on the racer frame, i used it to see how much speed you can reach with them, he uses it as a everyday get around. that why the padlock and chain is on it now.
     
  7. Next time you post a speed also post a pic of the bike the engine was on at the time and the sprocket that you used to reach those speeds.

    with a 26 tooth sprocket, the bike would have NO take off...you would have to peddle it up to probably 15-20 mph and then release the clutch. I can see how it MIGHT hit that speed with a 26 tooth sprocket, but it probably took 1/2 mile to get up to that speed (in my opinion)

    Yeah, and I got my bike to 55 mph with a 40t sprocket and I don't even need to pedal off of the line....

    I apologize but a 26t sprocket would require a LOT of pedalling off of the line. My HT with a 40t sprocket requires that the rider be going at least 6 mph before the engine will even consider starting. I could see how 46 mph would be possible but it would need to be during perfect conditions on a perfectly flat straight away. It would require a lot of pedalling however.
     
  10. Maybe he had the engine and bike in the trunk of his car when he was doing those speeds,lol.
