If you have the option of using a centrifugal clutch (I'm assuming you plan on installing a non-kit 4 stroke engine on your bike), then why not go with that? One less lever you need on your handlebars.

Oh and there is no manual clutch "kit" that I know of. There might be some designed for motorcycles that will work, I would suggest checking with a motorcycle shop for that. But none of the transmissions currently designed for motorbike use on the non-kit engines come with a manual clutch.

A while back, one of the DIY builders here modified a centrifugal clutch by adding spring loaded pawls that allowed him to pedal start his motor. I think he needed a compression release too to get the motor spinning. After it started, cent force kept the pawls dis-engaged. If you're handy at tinkering and modifying stuff, it wouldn't be too hard to do.

I have a 98cc Lifan 4 stroke. I didnt buy mine at home depot, but their specs say it has auto-decompression for easy starting. I dont know if thats an action of the recoil starter and the flywheel, or how exactly that works, but maybe somebody here knows what that means.

The auto-decompression mode is built into the camshaft assembly. The Predators and most of the Honda's ect nowdays have this

Don't know fore sure. You may need a cylinder head compression release, or a custom manual controlled valve lift device, as these have much more effect than the factory built in camshaft operated ones.
