I know you guys have seen this, please point me in the right direction. I have a 2002 K1200RS with 50,000 miles. If I fill the tank up (5 gals) the bike will stall at stop signs, will not idle and will be sluggish on accelleration, and clear up in 40 miles or so. If I stop at 3/4 of a tank (3.5 gals) or less when fueling up the bike runs great. I thought it was a tank vent issue but the bike runs the same way with the fuel cap open. Please save me from leaving my bike at the dealer for a month while they guess.
