Bike randomly died while riding.

Did the compression test today... All in the range of 55-65 PSI, engine was cold as it wasn't running. Just no idea why it's so low. Could timing be an issue?

Did you have the throttle wide open? Seems strange that they are within 10 psi of each other and all are equally low; service limit is 100 psi, - recommended range from the workshop manual is 128 - 170 psi.

If your compression is really that low, I doubt you could get the bike started, let alone running down the road. Are you sure you had a good seal on the spark plug holes when checking?

Some of the cheap compression testers are garbage. Even on a cold engine it should be higher than that if you can start it.

I cannot start it anymore, not even with a jump and starter fluid. I'll try again maybe there was something I missed - all plugs out throttle open

Yes, all cyl. being that equal and that low sure seems like something out of wack in the testing.

Agree with Griffin, I never remember me nor any of my riding buddies ever having a coil problem... My "83" 1100E has those yellow Accel coils and wires that previous owner put on, he probably thought they'd give him more HP as many folks did. I'd feel more comfortable and it'd look better if it had orig.

Please do yourself a favor and check your coils. Verify the resistance across the primary terminals is about 3Ω.

The only "coil problem" I have had was related to "yellow Accel coils" that were installed by a previous owner. My wife's '82 850L would destroy an igniter about every 2 or 3 years. When I finally decided to do some troubleshooting instead of just replacing, I found that the coils were the "high-performance" 0.7Ω coils. The extra current they allowed through the igniter was doing all the destruction. Installing some proper 3Ω Dyna coils fixed that problem for good. It has been 7 years now, it's still running strong (although with a different owner).

Pull the valve cover, time to check the valves/timing… something changed.. start over.

Perhaps you can help me. I have an 80's gs950g. I have rebuilt the carbs thoroughly and I still have gas blowing out of the intake on the 3'rd carb. I had a leak I couldn't find and after buying a set of orings, I thought I had her cased. Perhaps you have some knowledge??




truly yours,

Hi colin, best to start a new thread related to that issue and add some more info/pictures and it will get more visibility.
