80 GL1100 Starting Problems

Postby bugtooth » Sun Dec 16, 2012 5:50 pm



I am having starting problems with this bike. When it is cold, it starts fine. When it is warm, it just spins and will not start. It is like there is no fire to the cylinders. It spins fast and easy, just no results. Any help would be appreciated.

I am not sure about your model, but could it be that there are not enough jolts leftover from turning the engine over to provide a spark? Check your battery, by taking it to a place that can check batteries, and see if it is capable of charging up.

It may be that the alternator/generator is not charging correctly, and after you have started it first thing, then there is insufficient 'smoke' left over to charge the battery.

Take a lead off your spark plug while cranking a warm engine, and see if there is evidence of spark.

This should start you off, and others will chime in to add more info, if this does not work. Let us know how you get on, please.

Cold..tighter engine...higher compression.
Hot...parts expand...lower compression.
Check the valve clearance and adjust with the engine cold.
Or do a compression test when cold and then hot.
The bike will have a hard time starting when the compression is below 90 psi.
Too tight valve settings when cold can actually keep the valves from completely closing when hot.If the engine is spinning fast when hot,there's little compression to slow it down...

It's the "spinning fast and easy" that bothers me.That sounds like low compression.
If you can do a compression test...Pull all the plugs...set the gauge...Wide open throttle and crank for 4 seconds....Expect to see somewhere above 135 psi with no more than 5 psi difference between cylinders.
If it's below 95 psi...Adjust the valves and try again.
My original engine in my 83 had cold compression below 90 psi,also hard to start when hot.
I had to refresh the rings and valves to bring it back.
Well it did have close to 200,000 miles.

Thanks, again, Virgilmobile. I will post the psi tomorrow. It is cold and drizzling now and I am working on the patio, no shop. This bike has a little over 50k but has sat outside for 6 months. It needs a lot of TLC, which I intend to give it. I took off the trunk and bags today. They are the suitcase type and are for sale if anyone is interested.
