I think i might have a rider for my 1/4 mile run.I had a kid on a bmx pass me,at about 50 and he did not have a motor.He had 2 pair of tennis shoe's from pay less and the popo hot on his tail.When he gets out in 30 days,he's my new wheel man.Harleys Dad

I've had the popo on me for pedaling down hill at 45, in a 15 school zone. Criminal speeding....

thanks MrWW,
I put in my 20" rear wheel and 34T sprocket and it says over 7000 rpm at 30MPH. At 21" it says 6700. Should I measure actual diameter with tire? I don't think I am running that high. Also, what is the crank gear and clutch gear referring to? Are these the two gears under the clutch cover plate? Thanks Jim
