Bogging

[Kitten Tooth]

I own a 1982 Suzuki GS300L.
Sometimes when i start it for the first time in the morning, it boggs out really bad. I removed the spark plug on the left cylinder and the loss of power stayed the same. so the left cylinder isn't even firing.
but, it seems to go away when i reseed the spark plug cable. Can anyone tell me why
this happens?

what does "reseed the spark plug cable" mean? Try putting in 2 new NGK spark plugs.

Grab the spark plug cable while the bike is running. If you get shocked you have a spark plug cable problem.

Hmm, I thought that I shouldn't just leave it at that. You might hurt yourself. Not from the shock itself, but trying to get away from it.

Pull the caps off the plugs and make a resistance measurement from cap to cap. There's a spec on it - mine is 30k-50k. Now wiggle the wires while still making the measurement. Does it change? If so, track it down. it could be a bad connection from the wire to the cap. If it is, twist off the cap, cut back the wire, and reinstall.
