Bike has 9,500 Miles and has been running rich and hesitating at low and mid rpm's. I replaced the Air filter and cleaned all the plugs and ran Techron through 2 tanks of gas but still has this issue. It runs great at higher rpms and still a beast on the highway but cruising around town it runs crappy and smelly rich out of the exhaust. The Plugs had very little wear and very little oil on them and original with 9,500 miles but are the expensive lifetime NGK's. If it is a sensor - which one ? The FI light never comes on and all oil changes etc. are up to date.
Any real answers befor I take it to my 2 different incompetant dealers here in central Florida?

 

I don't know about the xx's but on the F4i's they have a problem similar when the fuel regulator goes bad. It lets gas into the vaccuum line which sucks it into the cylinders and causes it to run rich.
