    My 98 softtail custom sat for about 4 months. Started up good, but coughs and sputters when riding at a steady pace. Problem disappears when accelerating....kind of acts like it just needs to warm up, but problem persists even after riding a while. Some small backfiring, but not too much. Any ideas?

    Run some carb cleaner through the fuel system.

    What Glider said, plus FRESH fuel. Pretty much the same thing happened to my "92 Dyna Saturday. Hadn't been ridden in 3 months, started ok, but spit & stalled. I drained the carb and it had a bubble of water in the drain plug, and the gas smelled AWFUL! I drained most of it and headed to the gas station. It ran ok under acceleration, but spit'n sneezin at light throttle. About 3 miles after filling with fresh gas it was running right again. I put Stabil in it before I parked it this time.

    I have been told by a wise independent mechanic...with todays gas a carb cycle can set 4 to 6 weeks and the carbs can get messed up....Hence put in stabile...or keep the machine running to avoid carb issues.

    Welcome to the forum, I agree with all post's, sounds like old fuel and some gunk or water in the line, put some stabil in next time it sits long.
