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.
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.

Understood and thanks for the response. I just got my 2013 1100 EVO with 6500 miles. It’s bone stock. I love it but it’s just a little jerky at the lower rpms. I honestly think a higher idle speed would help with this.

The Monster 1100 has a stepper motor so you cannot change the idle. And there is no reason to.
Jerky at lower rpms?
Start by checking valve clearances and throttle body sync if it has not been done already.
Only then look into O2 sensor eliminators, ecu reflash, 14T sprocket, throttle tamer, etc...

I’m not saying it has a problem. That bike engine brakes pretty hard. That’s just the way it is. Just wondering if there was a way to help with it.

You mentioned your bike is bone stock. From the factory the bikes run very lean (for emissions) and have, in my opinion, too much exhaust restriction. My 796 was seriously herky-jerky at low RPM, it backfired through the airbox a LOT... the dreaded cough and die syndrome, usually at a stop light or in traffic. You HAD to launch it at 4000RPM... and keep it above 4000 to keep it from lugging.

I installed a set of Arrow slip-ons and the bike magically transformed. It starts easier, it rarely pops through the airbox, I can take it down to 3200RPM in traffic without problems, and the throttle response is far better. No other mods... I still run the factory airbox and filter unmodified, and OEM tune. It's sort of bizarre... you would think it would run even leaner with more airflow, but it doesn't seem to be.

Someone mentioned the 14T front sprocket... I would advise against that, although it's arguable. In fact, I even bought one... just never installed it after reading about the cons. I DID, when it was time for a new chain and sprocket set, went up on the rear sprocket, which helped immensely with in-town driveability... at the expense of top end speed. The good news is I can actually use 6th gear now.
