Loosen the rear axle nut mounting the wheel to the swing arm, then loosen the lock bolt on the top of the chrome adjuster ( left and right adjusters ), then loosen the lock nut on the long adjuster screw. Run the nut about 1/2" down the length of the adjuster screw. Now turn the adjuster screws equally in a clockwise direction to remove the excess slack from the chain. There should be index lines on the swing arm that the single index line on the chrome adjuster is referenced to. Example; If the chrome index line meets up with perhaps the fourth index mark on the swing arm on the left side, the right side should be at the same position. This keeps the wheel in alignment. When the adjustment is finished tighten the axle nut then tighten the adjuster lock nuts and then tighten the lock bolt on top of the chrome adjusters.

Leave some slack in the chain. Mid-chain you should be able to move the chain up and down about one and one half inches. If the chain can be lifted at the rear sprocket it is too loose. Lubricate the chain and the control cables on the bike. What condition are the front and rear sprockets in? The teeth should be bluntly rounded at the tip. If the teeth are sharp at the tip, or getting that way, then the sprockets are way past time to be replaced. Note that a worn sprocket can quickly ruin a new chain.

Please top rate this solution. Thanks!

Clicking sound from rear wheel

If shaft drive, check that the bolts are tight on driveshaft housing and also look for oil leak there.
Check/ Change rear gear oil. Tighten loose bolts

If chain driven, check/ adjust chain tension, a loose chain will make noise.
if chain is dirty it will make noise.

Other than that the only thing i can think of is you have a nail in your tire and your hearing it hit the road everytime it goes around

adjust the chain evenly at both rear adjusters until u have 1.5" at the center of the chain between back and front sprockets, rotate and make sure the chain is not stretched, if it tightens up between diff points more than .5" when the wheel is turned the chain is no good, replace it.

not sure on the exact specs but flip the carb upside down and look how the floats look to the horizon of the earth. Sounds silly but that is how pretty much all bike mechanics set them, just make them level to the earth. Good luck
