My 79 cx500 is only firing on the left cylinder. The right is getting spark and the carb is getting fuel. I rented a compression tester to see if that is the issue but they don't have a small enough adapter to test my bike. Any ideas what I should look for or what might be causing this?
Well, 1st off what is making you think its not firing on that side? Are you going by exhaust pulses? Do you still have your hbox on or not. My bike has the hbox removed and when I first got it I noticed there wasnt much coming out of my right pipe, I feared the worst like you. Checked and was getting spark, then it kinda became off and on (not riding it, just tinkering) someone had mentioned it may not be getting fuel. So my carbs are off right now being cleaned and they were pretty nasty. Not positive thats my problem yet, but very certain. You could get a spray bottle with gas and squirt thru that carb then fire it up and see how it does
I am certain it is getting spark... I have switched the plugs from cylinder to cylinder and switched the boots to opposite sides also. The plug would arc against the frame so I am sure the coil and wire are good too
