Default Re: Reasons for riding Motorized Bicycle

Okay,
it's rack mounted behind the seat. I took an old dax friction kit
and a 5/8" x 7" bolt from which I cut off the head. I necked that end
down & threaded it to 3/8" 24 thread so to thread it into the clutch
bell. For the other end I made a 3/4" pulley using two Belleville washers
with an 1/8" spacer between forming a tight V for a 3L wedge belt.
This locks in place with a 5/8" nut on either side. I had to grind the inside
nut to !/2 thickness & place a smooth 5/8" washer between it & the bearing.
The sheave was the rim of a 24" wheel notched to fit the spokes &
secured with aluminum strips held by self-tapping screws.
It looks like this: (if i can get it to load) What looks like a pannier is
a stealth cowling over the engine,(tanaka pf4000).
