I need some help. I have an 09 RG with rinehart slip ons, SE air filter and was race tuned when I got it. A few months ago it started an erratic idle once warmed up. It idles at 1000 then jumps to 1200 then down to 950 back to a 1000 then 1200...and on it goes. The gas is fresh, the air cleaner is clean and tried running with out air filter to see if that helped. It was an annoyance as the bike ran/rode great, just had a quirky idle. Recently I installed TW6-6 cams, PCV & autotune and it is doing the same thing but now runs very rich on idle, but great riding with no issues while riding, come to a stop and it idles really rough but does not stall. I'm seeing 11-12 AFR on front cyliner and 12 AFR on the rear cylinder on idle, I smell raw gas at the tail pipes but it is not belching black smoke.
Can this be the TMAP sensor dirty or gone bad? Could it be the temp sensor in the head? I don't think I'm the only person who has had this come up and hope that there is a fix to be had. Can you share what you found and what the fix is?
