Default 5hp briggs bike

i have a 5 hp briggs off roto tiller on a bike
the motor cant rev up its geared to low? does alot of bogging and doesn't have enough torque with this gear setup? 10 to 10 to 10 to 50 with a jack-shaft
was thinking 10 to 20 to 10 to 50?

Howdy Briggs, welcome.

There are some great builds and builders who used your engine. A ton of information.

I LIKE those bikes! What engine is it exactly?

And are those custom built or does a company sell them?

They're all hand made on vintage Schwinn frames. Here's Briggsbiker's kick start bike.

welcome briggsandstratton,a few things..do you have a clutch?you probably need to peddle to get bike up to speed,then slowly let the clutch out.there are different kinds of clutches to use.try on a slight downhill to get up to speed.one thing i have found out is having to try different ways of operating these machines.kind of have to see what it likes/wants....that 5hp should sling you down the road pretty good.
keep us posted,good luck & have fun!
