I'm putting it on a ccs charger. I'm shooting for making the jac-mount like it would have came originally in that ad I in my first post but that's the only photo I've ever seen of this setup and it's not very detailed. I have comet 2 speed stuff that I can use but I'm not sure if it's correct or how it's suppose be setup. I would be nice if someone had some detailed photos of a original comet jac-mount.
James, that's not the problem here.
This is far more complicated than you think. You only have one option for a driver clutch unless you have a dual sprocket vintage clutch with an odd numbered tooth count. The tooth counts determine the centerline distance and the chain length. The Lil indian jackshaft plate is nearly identical in design aside from the "shift lever." My build-off bike will help you to see what it should look like. I went through multiple scenarios with the help of Jim Donovan at Max-Torque (hours on the phone) to figure out what works and what won't. My thread gives you all the tools to make the calculations you have to have and
how to do them.
You need to know the number of teeth on the driver clutch, the one-way sprocket and the driven Comet secondary clutch. The presently available (and there's no reason to think it's changed) is a 12 driven secondary and a 24 one way. You will need an odd tooth count driver clutch for
any hope of making this work without 1) huge slop in one chain or 2) a skipping chain. From the looks of your plate, I imagine you've got between 7 and 8 1/4 inches of centerline wiggle room. All of this is also dependent on the length of the slots on the engine plate.
Calculations have to show a chain link count as an even number for both chains and there should be a 4 link difference between chains based on a #35 chain. Gold chain (Kart) will not work as it is too wide for the dual sprocket clutch and drivens.
