It helped some. I have to say, I ended up selling it and getting an SF848 with a rexxer tune and remus exhaust. Was much smoother. Then, I came across a great deal on a 2012 1100evo with termi package and 20k miles. It was much smoother than my 1100evo anniversary with 700 miles. I don't know if it is the new ECU/Termi or the miles, but I sold the SF848 and got the Monster 1100evo which I still have. It is really nice. It is even better after the 22.5k miles major service. It is more comfortable then the SF848 (a bike which I loved but could not get comfortable with as well as in handling). Ultimately, a $400 Rexxer tune makes a big difference as well.Hey guys not sure if this forum is still active, but when the O2 sensors are disconnected would this help with idling or hurt it? I’ve notice when my monster is idling it stays at a pretty low rpm and almost seems like it’s not getting enough fuel.
