Hi, my Yamaha 82 XJ 650 is not starting engine turns over and choke is all the way to the end, I think the carbs are overflowing with gas . what should I do thanks
Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
Is the handlebar kill switch on? Is it shorted out?
Are you getting power to the coils?
Check the fuses. How good is the battery? Try a jump start from your car battery.
Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing. If still no spark, get CDI system and coils checked at the dealers shop.

looking from the left side, the crank spins counter clockwise. I'm intrigued how you would turn it backwards, if you touch the starter or kick start, it is going to go the correct way. If the tensioner is working it shouldnt slip anyway
weak mixture,dirty fuel,air leaks on induction manifolds,jets blocked,fuel tap filter chocked,float needles sticking,fuel level in carb incorrect,thottles not opening together,air leaks at exhaust pipe joints,
