Bad gas???

Hi guys. I have a K1600GTL Exclusive. I wasn't able to ride for about a year, but I kept the bike on a trickle charge and started up about every month and let it run for a few minutes. I recently started up and took it out but having a little issue. Rough idle, loses power when I roll back on the throttle a little to quick and now a check engine light. I am thinking the gas is the problem from sitting to long. I wonder if getting the old gas out and running a new tank or premium would help, maybe add something like Sea Foam or do I need a trip to the dealer???

I would start by doing that for a tank or two and see if it flushes things out. The ethanol in the gas would of absorbed water, possibly gelled and left a varnish on the injectors. If that doesn't help take it to the dealer to pull the codes and see where the issue is.

Re: Bad gas???

Gas is of questionable quality after 90 days, much less than a year. The alcohol tends to separate. Yes, your problems are fuel related. I would try to remove as much of it as possible if you have not already and fill up with fresh fuel. As you suggested Sea Foam or Techron concentrate plus should be added. And, starting up the bike for a few minutes is not a good plan. Better to not start it at all if you can not go for a ride to bring up to operating temperature. The dealer might offer an injector cleaning process if needed.

Re: Bad gas???

Thanks for the reply guys. Pretty much what I thought. Im going to drain the tank and run a full tank of new gas with Sea Foam and see where that gets me. Going to the dealer is a last resort, they are about 40 miles away and I would have to rent a trailer as riding would be a bad idea at this point.

If riding it 40 miles to a dealer is a bad idea, how do you plan to burn out that tank of fresh gas?
