The belt in that torque converter should wear a little and the sides will glaze which should help to make take off a little smoother from some belt slippage in the beginning. 

Maybe check around to see if you can find some different tension springs for the front variable pulley to engage at a higher RPM ????

Larger rear sprocket

The sprocket is an easy switch standard 3-bolt pattern. Was also considering upgrading the rear spokes anyways as per Handy Don suggestion.

The springs, now that not sure of, have to get a picture to you of the innards, not like the one’s I’m familiar with, seems cheaply made compared to the 40’s.

Originally made for the death row kit

I saw a ‘Tube video (taken by a friend) of a fellow taking delivery of a brand new crotch rocket. About 50’ into his first ride, while leaving the dealer’s parking lot, he goes for a wheelie and flips over backward. He’s hurt and the ‘cycle takes a beating.

Ouch! When I was a younger man, wheelies were all day long on any bicycle all around the neighborhood on rear wheel.

I had built an English Racer about 12yrs back, figured I’d hop on and ride a wheelie  right, wrong! On the ground with knee injury, knee cap on the side of my leg!

I watch this one motorcyclist on YouTube, she’s always doing wheelie stunts and I cringe…

I've used a couple of the $100 chinese knock offs for projects. My WH bike uses one

Nice job, that looks like a hand full.

How is the rear sprocket attached to the wheel?  Mounted to the hub or the spokes.   Remember no suspicion.  I built one for a friend, had a 49cc motor, made it look like a old messenger bike. 

Seemed a little under powered. Looks like you got that handled. 

Nice job keep it shiny side up.

They can be a handful! The hub adapter sized to 1.6 to mate with the Schwinn S7 single speed wheel.

That leaves about 6 thousands of clamp space.

nice job on the messenger, color is dead on! 49cc, 79cc?

I may find another set of drive springs for the CVT Transmission, engage at higher rpm.

Tell, ya tho’, you think everything is tight, but needs to be “good & tight!”
