75 cb550 cylinder not firing
« on: June 01, 2012, 10:38:42 PM »
I just finished putting my bike back together and i started her up and let it idle for about a min and shut it off.... i put my hand near the number 4 cylinder exhaust pipe and it was warm so then i touched the #3 pipe and it was hot as f*%k so it ended up being clylinders 2 and 4 not firing and checked all the wiring and it was fine so im stumped? Whats the problem?
