Rough running K12GT
I have a 07' K1200GT with 14K miles which has always run very smoothly. Last December I put the bike away for a few months in the garage, I filled the tank with Premium gas and put in some gas stabilizer. When I took the bike out this spring it was idleing really high about 1500 RMPs and backfireing on acceleration between 2000 and 3000 RPMs. No back fire on slowing down just during a slow accelleration between 2K and 3K.
I thought I would see improvement after burning the 1st tank of gas. but on the 2nd tank there was improvement but no cure.
Does anyone have any ideas what might be the problem?
