bike runs rough at low rpm (not herky jerkies)
Started noticing the bike running rough around idle at lights today. As my ride progressed it got so bad that I stalled out at a light, which I haven't done since my squid days. I noticed that it s sounded really throaty and choppy at low rpm cruising, almost like continuous back firing.. It a would act up a around 3500 rpm in 1st, 4500 rpm in 2ND, but clear up at higher rpm. I got gas from a different station last ride, so bad gas? I put it into dealer mode and got no codes, and tps is perfect. It has slip-on, TRE, and SET valve mod Any ideas?
