Welcome to the forum. We're here to help. And I know exactly where Cooper City is
I'm an old Florida transplant.
Two things come to mind. Either your clutch cable is too loose or the chain alignment is off.
Where the clutch cable attaches to the engine (clutch actuator arm) there should be little to no slack in that cable. It must be able to pull the arm in about an inch to fully disengage the clutch. This is a very common problem and tightening the cable usually fixes it.
If the chain alignment is off or if the chain is too loose or too tight it might be derailing at the front sprocket. There is very little room inside where the drive (engine) sprocket is and the chain can bind if one of the two problems exist.
If the engine is not mounted exactly square with the rear wheel (driven) sprocket that can also cause a problem. Make sure the chain runs in an absolutely straight line between the two sprockets as viewed from the rear looking forward. It can not run at an angle.
As for tension, you'll want 1/2 to 3/4" slack in the chain. Measure this by leaving the clutch engaged (handlebar lever out) and roll the bike forward gently until the piston comes into the compression stroke. The top chain run will then go slack. That's where you want the 1/2 to 3/4" of slack.
Good luck. Let us know what you find.
