1988 1500 won't start cold.

Postby adsooter » Tue Sep 06, 2016 3:54 pm



Hi guys,
I have a 1988 gl 1500 that runs great, a little lean, but not a problem. The problem I am having is when it sets outside overnight and the temp gets below 50 it is a bitch to start. It cranks fast and the choke has so influence. If I cycle the key off and on about 10 times and try it I will fire one time, but that's it. Let it set for 2 to 3 minutes, it will run if I get the engine cranking a get off the start button while the engine is turning over then it will run. After that its good all day with just a quick touch to the start button and its running. Any suggestion where to start?
Thanks

Sounds like your choke/enrichment isn't functioning at all!

Hi Dusty,
Yes the choke is working, after it fires the choke is needed to keep it running and will increase the rpm to 3000 and it will drop the rpm's the more I take the choke away to a 1500 warm up rpm. Above 1500 feet sea level the choke is not needed to maintain smooth operation, below 1500 I have to add a little choke maintain smooth operation until the engine temp is above the center point. I have a though it is not firing the ignition due to something in the system--maybe.
Thanks for the reply.

:idea: Try depressing the choke lever about 1/4 of it's travel and try starting it.

I have a 89 which tends to be cold natured, if your like me my carbs haven't been overhauled,
try this, open your breather box, remove filter, crank bike keep it reved around 2,000 rpm,
take the palm of your hand and block opening on one carb till it almost dies, keep it runing
and do the other carb the same way keep it runing. Burp the throttle a few times.
do this whole process aboult three times this will help clean air ways for idle circuit.
you should also check for vacuum leaks.

Normally, if the engine starts as the start button is released as it is cranking is indicative of a weak battery. Do you have an on-board voltmeter? If not, attach a voltmeter/VOM to the battery and monitor the voltage as it is cranking. If the voltage drops below 10 volts, the battery needs to be replaced.

As to the enrichment, if the bike has sat for a few days in cold weather, the choke lever will probably have to be moved all the way down. If it has only sat overnight, it should stat fine on 1/2 to 3/4 travel of the choke lever. At least that has been my experience on the 1500's I've owner.

It might be a good idea to run some Seafoam, Gumout, Techron or Marvel Mystery Oil (your choice) through a few tanks of fuel to attempt to clean the carbs.
