89 gl1500 only runs on full choke

Post by gasnell » Sat Mar 13, 2010 9:04 pm

I let my bike sit for three months and now it barely starts and will only stay running on full choke. Gie it gas and it dies. Any ideas on how to cure it? Thanks, Greg

If it ran good before you parked it, then you will have to clean the carbs. Three months is right on the line of cleaning the carbs or not. Drain the carbs first and change the plugs, then see if that helps. When you drain the carbs smell the gas. If it smells bad or come out dark, then get ready to pull the carbs.

You could try running a can of Seafoam through it. I know I keep talking this product up, but it's worked so many times for so many people. If the alternative to pulling carbs is dumping a can of Seafoam in the gas tank, I'll try the Seafoam first.

Drain the gas, fill the tank with fresh gas, and half a can of Seafoam. Run that tank through, then try again with another tank of fresh gas, and the rest of the can of Seafoam. If it improves, just keep running more and more Seafoam until you're back to normal. If it doesn't improve, it's time to pull the carbs and clean them manually.
