| | Re: Quarter Mile times i'd do under 35secs on a 1/4 mile easy.
shift kit and tuned pipe, start the in 2nd gear and rev it to the powerband and shift into taller gears all whilst keeping the engine in it's powerband + 'on the pipe' |

This is why all the other "speed" threads keep getting shut down, no offense man but clock it for real.

| | Re: Quarter Mile times This would be the first time 1/4 mile times are measured in minutes in stead of seconds!

i will when my arm's out of plaster.
50km/h = 830m/minute
1/4mile = 400m
400m in 30 secs @ 50km/h
my bike is capable of 60+ km/h in 8th gear ( 60km/h is the speed limit of normal streets here ) and accelleration is the only issue, considering this bike pulls me up hills in 6th gear @ idle revs i'm pretty sure i could start in 3rd or 4th gear and accelerate quickly enough to do <40 second 1/4 mile.  |

I said i would do a 1/4 mile time when my arms out of plaster... No need to shoe me away and say' blah blah post numbers' when i cant even ride my bike with only 1 arm...
numbers posted before were to make people aware that under 1min is reachable for most and that no 'hour glass of sand' would be needed
anyways
meh. good luck to you all, i'll just stay here and ride when i can in a few weeks |

| | Re: Quarter Mile times No hard feelings man - it's just we've tried so hard to have a "pure" thread with valid numbers, each and every time - the armchair racing begins.
It's not that we don't believe you or that we don't wanna hear it - but it escalates so badly with people making ridiculous claims, outlandish boasting, and out of this world "math" and every time - the thread ends up closed 'cause it's impossible to find the real buried in the BS. I hope you understand.
I hope yer arm heals soon, it'd be great to get some numbers with a shift kit!  |

| | Re: Quarter Mile times I will gladly run some tests and supply the information you desire. However I will need to wait for the right weather conditions.
So far all my tests have been using a 150 feet.
I can supply speeds & times, but need to know what the basics are for the tests. How much information would help? Rider weight? Gear ratios? Etc?
Do you want 1/8 mile [660 feet], 1/4 mile, standing start, which size motor?
I can use either a modified Whizzer 138 CC 4 stroke, or a 49 CC 4-stroke on my 24" EZM proto-type. I can also supply times with either the Honda or HS motor. All my bikes are single speed.
Have fun, |

| | Re: Quarter Mile times I didn't get it, the way you want do make the 1/4miles times. So...the time is counted when we start pedaling from 0miles, right? | | Thread Tools | | | | Display Modes | Linear Mode |
