Discussion at hand.

Wondering if a CVT on the twins; would the - could the twin 97cc engines at 7hp total when combined, spin up a CVT made for 196cc 6.5hp engine?

I think the small Comet is rated for up to 8hp You should be good to go...http://www.mfgsupply.com/gomini/gominiclutch/gominiclutchtorq/gominiclutchtorq30.html .... Curt
Thanks for the heads up. I am building my own JS and I see these parts are available where I could use them in what I have envisioned. Of note I see they have this

30 Series Driven Unit, 5/8" Bore, 6" Dia

I have not purchased a clutch yet and need to consider this option. Final parts ordering will take place Aug 8th.

You really should find a better way to secure that drum. Maybe weld a secondary bracket around the fork where the tab is welded for extra support and also to take some of the load off that one spot where the tab is welded. I'm concerned for your safety, and when the tab breaks off and your brake cable wraps around your hub, locking your wheel and throwing you from the bike at 50mph, I'm going to feel very bad for you. Ask bairdco what can happen when a homemade brake arm bracket fails.

He's responsible for his own actions, and as long as its inspected every time and the bike isn't stoppied I think it will prolly be OK.

Nice build. I have a cvt go kart drive, not installed yet. Think you need drive and driven parts as the belt is flat on one side.

You could use a go cart centrifugal clutch on your jackshaft, belt or chain model.

Will finish my stretch cruiser build when my Swing Blade Lumber Saw Mill is finished.

LabRat,
Have you considered running 2 centrifical clutches ( one on each engine) with one modified for pedal start application.
Also when modifying forks like you did I would re inforce the inside of the tubing by sliding a piece of tubing in it , then weld it back together, basically doubling the thickness of the forks in that area.
With that said your machine is looking great!

Nice point on the forks, but yes this is how it was done. The solid piece is set into the fork.

Starting the engines is simple start one the other starts.

Still undecided on the transmission. I have all the parts except a clutch and chain.

The on frame / welded into the frame gas tank is yet to be built but I have killed a few sheets of cardboard fiddling with the 'look'.

The engine plate in place now. Clicking through will show the angle of the support post is the same as the original seat post. This post blocked off and welded to a cross member plate. The bike will have a custom seat pan.
