I unloaded my 2004 800 off the trailer today to put another sled on and after 15+ pulls to get it started it seemed to idle too high. Like 2000-2300 rpm. I would burp the throttle to 3-4k rpm and as it came back down would stall at 2500 and settle but wouldn't go below 2000. Seems like when I put it away last year would idle at 1600. I changed out some switches for the thumb warmer and hand grip warmer and replaced the thumb throttle. It seemed like everything went back normal. Do I need to adjust my idle down at the fuel rail???? Lots pf staibilizer in the gas, will that make it idel too high??

High idle is a lean condition, you could have a little gunk in your pilots, try some carb cleaner. It could be more serious and you have a crank seal leaking, you can test that by spraying some ether in behind the clutch and through the timing hole when it's running, if it revs up more it's sucking air! My 900 always idles high at home because of the low elevation, idles fine up high.
Digg is correct. More than likely crap in the carbs. Easy fix, just takes some time.
had this happen on my 07 m1000, it was from the throttle cable coming out of the throttle block just a tiny bit once when the cable got pulled on by something. It can be very difficult to get the cable all the way back in, sometimes even have to disassemble the throttle block again. When the throttle is cracked it can override the choke and make it hard starting, because to much air comes in instead of pulling fuel.
It's an EFI, so the dirty carb isn't it. The only thing that changed from the last time I rode it is replacing the throttle. It's probably pulling on the cable a little.
A slight pull on the throttle can make it start hard also.
I adjusted the throttle cable to spec, with just a touch of slack in it. Finally got enough snow to rip it in the backyard and it pulls just as hard as it ever did, but when you come back to idle it doesn't smotthly drop back it like rum rum rum 3 times and then will either idel or die. It starts right back up and run fine. I pulled the plugs and they were a dark brown, so I don't think it's leaned out. Any other suggestions? There a lot of fuel stabilizer in the tank, I think I'm just going to run it out this weekend and see what happens. Like I said it seems to run just fine.
I sold this sled to a friend and we took it out today. He's a beginer and I forget how much torque these sleds put out. It ran fine. He did get stuck and rolled it and wouldn't start. Some snow had wedged the throttle half open and I saw that was the problem and cleaned it out and started 2 pulls. So to finish this thread I think having the throttle part open makes it hard to start. Silly computers.
