Honda 919 Idle RPM

I just bought an 07 Honda 919 - it idles at around 1500 RPM, is this normal? It feels a little high. Just curious if anyone else idles differently.

Too high. Should be 1100 -1200 off the top of my head.

The idle adjuster is on the left side by the injectors - a yellow knob (colour off the top of my head again!) - turn to adjust - one way will increase one lower.

But first - check the high speed idle start knob (on the left side just under the tank rear of the block) - black knob with a white symbol on it, is fully pushed in. Pull out before starting a cold engine and it increases rpm - push in to lower during warm-up (no more than the time it takes to put your helmet and gloves on) and push right in for riding. It may be slightly out if you have not touched it yet.

Also check the idle when warm does not increase if you turn the bars full lock left or right - if so the throttle cables are binding somewhere.

Just don't do like the Harley guys and set it too low just to get a choppy idle that makes it sound like it's got a big cam.

Hi everyone.
Can anyone help me with an advice.
My 919 2002 RPM IS going up and down at idle. The motor sound is high then low. Never steady and smooth.
I tried adjusting from the yellow button on the left side. It didn't work.
I am not expert at all but I feel the intake of air is high.
Can anyone tell me what it could be ??
I just bought it and it is in an excellent condition.

First question is usually what was last done to the bike, but you may not know that if you just got it. I have never heard of a 919 taking in too much air. A few things you may want to check.

1) Battery condition. Sometimes a battery that's getting ready to go will cause some strange running conditions?
2) Does it do it when the engine is warm and cold? Mine will hunt a little on start-up, but not when it's warmed up.
3) When you first start up, do all the exhaust header pipes get equally hot. If the middle ones are cold it could indicate a bad Fuel Pressure Regulator (fairly common) or loose coil or plug wires.
4) Check all vacuum hoses for leaks.

I'm sure some others may chime in with other things to check.

Good luck!

Yeah they are primarily under the tank. I would start with just a visual inspection to look for cracks or dry rot. While the tank is up you can check all the wiring to your coils (special attention to the small wires).
