OK SOB !!! to go 40mph with a 44 t sprocket i must have been reving her close to 11,000 rpm!!!
tire size 26in
10 t drive and a 44 t rear = 4.4:1 rear axle ratio
motor ratio is 5:1 reduced i think
and speed was 40 miles an hour i believe ... i was passing cars going 35 !
those numbers give me and engine rpm speed of 11,372 !!!
using this calculator
even if i say i was only doing 35, the same speed fo the cars i quickly passed the rpms would be ......... 9,951 !!!
