Hey guys, I am building a Micargi Rover GT with an ebay 66cc stock kit and an ebay 119.00 china jackshaft kit. I know the kits not the greatest but im trying to make it work. The kit i got had 4 mounting plates, one of the four is just a chain gaurd. This is my second build with these kits but I am pretty good with mechanical things.
The problem I am having is that when the clutch is engaged and locked, even if I push the clutch arm in with my finger, the crank cannot turn the jackshaft. I dont have the drive chain to the rear wheel on so it should just spin fairly easily when the clutch is engaged but it doesnt. I know that the crank and bearings are functioning so the clutch has to be the problem. I took off the clutch cover, removed the flower nut, the plate and spring. I cleaned out all of the friction pads (They are made out of rubber that looks and feels like pencil eraser) anyways i removed the exess and cleaned the area up, broke loose the clutch plate floating guides and greased the bearings and gears. I read about an issue with the grease drys and binds this process and this seemed to be my issue because it was pretty stuck when I first did this. At this point in the process the floating guides were still not moving freely but they did move with minimal force. So I reassembled the clutch, adjusted the flower nut a quarter turn out from the stock position and tested the lift. It seems to lift about 1/8 inch, maybe a little more, when engaged. I put the cover back on. Reassembled the engine, soft mounted it to the bike with a mock front mount, because its so far from the motor im going to have to make one that fits. Anyways, i just want the engine and jackshaft to turn. I know the jackshaft to pedal crank chain is loose but it should not affect the crank from turning. I have tried adjusting the clutch lever and i know that it is engaging there is no slack in the line. Please help, I am out of options here.
I know its pointless to put a jackshaft on a single speed bike, but aesthetically its perfect. Here are some picks of the jackshaft and how its set up.
