No offense taken KCvale...
Id be amenable to move this over to the Electric bike threads.
Maybe together we can figure out a better mouse trap.
I agree with you 100% on the Jackshaft/gear set up.
I run a Morini S6-s, with an SBP Exp.pipe with custom made 24" long X 3/4" head pipe, on a SBP shift kit (custom made mounts) and I run a shimano 42t chain ring and a 9 speed, 11t/36t cassette and an XT derailleur, I find this gives a good range of gearing for riding city streets were top speed isn't as important as acceleration.
So far, after a 2 tank full, 25:1 Castrol 2 stroke/premium gas mix break in period, I've thinned out the mix to 35:1.
Its getting 120mpg so far with less smoke.
I had to loosen up the clutch a little because it was like an on/off switch, now she slip's a little first before locking up.
Top Speed so far on level ground, with me riding, hauling a 300+pound load, no wind condition, has been 48+ mph, With my 165lb friend in the saddle shes done 54mph with a little left over.
Those numbers dont take its broad torque band into account, this thing really pulls away with authority, I can power lift the front wheel easily.
Lets take up the electro set up in that thread.
