I'm a little worried
I'm approaching ~9,500 miles on my '09 FLTR and it seems to be acting a little wierd these days. While it starts, idles & runs well, the engine seems a bit "fragile" when leaving from a stop. Unless I give it just enough gas, it seems to stall fairly easily. It stalled for me in stop-n-go traffic this morning. Then at a light, the light turned green and I went to go, it almost stalled, I tweaked the throttle, it coughed and a BIG puff of black smoke came from beneath the aircleaner! It didn't stall - just came close. The idle was a little shaky right after this, but I got where I was going. Now I hope I can get home this afternoon.
I was going to do the 10K maintenance and check things out, but wonder what the hell's going on. FYI - I've got a stage I upgrade (Bub7 TDs, Big Sucker, and a PCV), otherwise stock. Any thoughts???

I think it is the heat management system coming into play. I had a PC V on my 09 RG and the same thing happened as the weather warmed and I was in some traffic. Jamie sent me a map that ran a little richer and suggested I rev it up a bit to get both cylinders firing before moving. This is my opinion as to what is happening, could be wrong but is sounds very familiar....Good Luck

I had similar issues when the heat management system was active (black smoke from air cleaner, trying to die at take off). I just turned off the heat management, but I am interested in what others have done to combat the problem.

I've been talking (e-mail) with Jamie to fine-tune the map he put into the PCV, as I'm getting a little popping on deceleration (no popping when I just rev the engine). I need to send him my map and he said he's adjust it. Maybe this is playing into it???
I don't know ANYTHING about the "heat management system". Honestly, I've never even heard of it! What is it and what (if anything) should be done to deal with it?

I haven't done anything yet (other than experience what I described....and worry about it!). I'll pull the plugs & give'em a look when I do the 10K service.

Heat management system shuts down one cylinder when idling and temps hit a certain point to help deal with heat issues.

Like some of these guys, unless I pay attention, when the heat management is on, I sometimes almost kill the bike before taking off from a light. I've just learned to blip the throttle before I take off when the back jug's shut down.

I agree its the heat management. It happened to me a couple times. You can barely tell when it kicks in. I also blip the throttle to get both cylinders firing before taking off in traffic when it's activated.
