Re: CVT semi manual pulley adjustment

OK now I need to find the drawings for that Saturn car. after that demo it seems almost too easy to manually control that GM CVT trans. I'd mate it to a Kubota V2203 diesel engine and run set the RPM to it's sweet spot. then adjust the transmision to regulate the road speed.

Re: CVT semi manual pulley adjustment

I'd like to see if it could be cable or lever actuated with a fail safe, in that if operat...

Re: CVT semi manual pulley adjustment

who makes a semi manual CVT for a custom build? I like the idea of being able to run the engine at a fixed speed and use the CVT to govern the bikes speed.

yeah I know it will sound like a lawn mower droning away as I ride, I don't care what it sounds like.

Re: Secondary drive freewheel

What about a way to manually force the fly weights back while the engine is running, kinda like slipping the clutch on a standard gearbox.

CAD Drawings who has them

I'm starting with nothing so, I'm looking to put togeather a collection of drawings for both stock gasser and diesel bell patterns. during this quest I'm interested to see how the V-twin Yanmar type diesel will fit in a BMW R100 frame, or other simalar type shaft driven bike.
