Where is the speed estimator??
I just went for a high speed blast and would like to figure out how much of a high speed blast it really was. Stats are :26 inch tall tires, 4.10 gears, 4 speed. So the question is, what speed would 5000rpms be in fourth gear?
I ended up breaking the fan belt and am looking at switching to the March setup to avoid that problem.
thanks,

Looks like you are experiencing the 'I need one more gear syndrome'. I have a bad case of it and my doctor prescribed a t-5 transmission as the cure. Many other 'drugs' on the market that are just as effective but the t-5 just fits my situation best. Although not life threaten persay, this sydrome can have very accute attacks when coupled with a ricer on the highway who can go 140.
