Here it is. My solution to quick and easy transport around town.
Its taken around 3 months to get to its finished stage but right now im just chasing down gearing problems and jackshaft issues.
So far its been able to run nicely at 80km/h (50mp/h) and ive had it at around 100km/h (60mp/h) but my gearing is still too tall

below are some photos of the build process.

Easy way to get reverse direction, bigger sprocket on jack shaft input side, would cut the gearing down a lot.

Neat build..............Curt

It's currently going 10 tooth clutch. 14t either end of the jackshaft to a 48t.

Thinking about going 16 on the input side of the shaft and 56 on the rear
 
Nice fitting the engine in just the space in the frame. I have a Briggs 3.5hp that just fits, but you got like 5hp there I see. I see on your build that the chain from the clutch to the first jackshaft axle could connect to a larger gear. And as you mention too maybe a larger sprocket on the drive wheel. I've been using 12:1 ratio which works for me with the 26 inch drive wheel on my bike. I could use greater reduction as much as 20:1 as I only ride trails off roading. Welcome!
