Nice bike :) Without modification, that sprocket adapter is actually more dangerous than the default ragjoint setup. With the default ragjoint, your spokes will probably be fine if a bolt or two loosens up because there's more friction points from the other bolts. You'll notice a wobble or drivetrain problems and you can true it up. With that setup, all it takes is for that one hoseclamp with the little screw to loosen up a bit and you can do serious damage to your spokes because the entire assembly will rotate as there are no friction points anywhere else. The way around that is to ignore the instructions and use it along with the rubber bushings from the kit.

That adapter is the one I was talking about. And no it doesn't "bolt to the hub". That hose clamp is not a bolt. There's no way you can clamp that hoseclamp down tight enough and secure enough to withstand the torque over a long period. Even if it loosens just a bit, that's enough for it to completely spin and tear out your spokes. You need the more expensive CNC sprocket adapter. It uses two class 12.9 steel socket head screws into helicoils to secure it to the hub, so you can torque them down with a long-handled socket wrench and loctite and it will never come lose.
Sprocket Adapter - seems like the hub is narrow in the middle and then flares. Do you measure the center of the hub for the adapter or the flare end? Many of these seem to fit only a 1.5 diameter hub.
Your spring tensioner, I followed the link, it is a Russian part and the roller pulley does not have side walls. It looks a little concerning to me that the chain could wiggle off a side. www.ebay.com/itm/142474439092
have two different kinds for one with the hose clamp and the one with the two screws and both seem to work fine just take some sandpaper rough up Hub and inside of adapter
Your carburetor is not working if it worked before Troy Springs from carburetor cleaner in it just pull off the Breather sprayed in it let it sit for a while and try to crank it
Don't smoke cigarettes on camera, and quit smoking. You should put the links to items used in the descriptions. I REALLY need the hub mount sprocket support, but like the other viewer says, I have the skinny hub which is 16.5mm.
