gl1200 will not run except with choke

Postby rcmanwood » Sun Oct 20, 2013 5:14 pm



gl 1200 will not start or run without choke on. Was running fine and then I let it set up for about a month and now it will not start without the choke on and then it will not accelerate. It also backfires when trying to accelerate. The carbs were overhauled a couple of months ago and it ran fine after that. When the choke is turned off it dies. I also cleaned the fuel filter and checked the fuel pump and it appears to be operating fine. I am lost on what to do next. Any help would be appreciated.

Has it been run much since the carbs were overhauled? Or was it just sitting?

My guess is you have a rusted tank. Fine rust has found it's way back into your carbs. The only cure is to remove tank and clean it with acid, then re-clean your carbs. I've run into this TOO MANY times in past years with my old Hondas, it's no fun!
Motorcycles:
'81 Honda CBX 1050 (current and forever)
'03 Honda RC 51 1000 (current and forever)
'75 CB 750 K3 (for sale) good running bike
'86 Honda Gold Wing Aspencade, (the Ratwing)
too many more to list..................

I would check to make sure you didn't knock off a vacuum line. Make sure all those vacuum lines are attached and not cracked. Will make it run funkey when one is loose. All good. Before pulling the tank, was there anything in the fuel filter to indicate stuff coming from the tank? Next check the sync on the carbs. Drain those float bowls and put a clean rag under the drain. If you get good clean gas out and the fuel filter was clean, I would say forget the hassle of pulling the tank.
Next would be to try some clean fresh gas. Maybe you got a bad batch.
I'm still thinking vacuum problem with the sudden onset.
Any time the bike sets for more than a week or two I always add some fuel stabilizer. Of course the fuel here is worse than other states.
Do let us know what you find.
Enjoy the ride. They are all good, just some better than others.

Some have had luck. But if the bike sat for any length of time, that crud the fuel of todays gasoline leaves is imposable to clean with out removing the carbs. The pilot jets in in the wing are very small and clog very easily. I myself use Star Tron Fuel Stabilizer.
Find it in the marine section at Wal-Mart. Good luck. Just remember to add fuel stabilizer anytime the MC is going to set for more than a week or two before getting fresh gas.
