fast idle 990

My "not so commonly ridden" 2006 990Adv is acting strangely. It starts nicely, idles at 1700 rpm which is a bit high from my understanding. When riding, if pushing the clutch or at the stop light the idle stays at 2100 ~ 2200 rpm.

The worst part is that i need to do alot of braking as engine is constantly pushing the bike further, not much engine brake here.

Any suggestions?

You probably need to check that your TPS is adjusted correctly when hot. You'll need TuneECU and a cable. There is alot of information in this section of the forum on how to do the adjustment.

I suspected that, but it doesn't do it all the time. Sometimes it act just plain normal... jerky as usual... and then starts to accelerating..

Mine does that when it is really cold outside and i don't warm it up properly.
I've learned to warm it up to 2-3 bars every morning, problem solved.

No cold here, ranging from 20-30 celsius. Yet i usually let it warm to first bar before moving out of the garage. After that it goes quickly to 4 bars.

Also noticed that when starting to move she sputters lightly and sometimes will even stall almost if running on only one cylinder.

After that will not sputter anymore... maybe dirty trhottle bodies/injectors?

I thought 1700 was normal, that is where mine sits. Would much rather have it idle closer to 1200.

I have had that kind of problem. Usually it happens when engine is hot and I take off immediately after starting the engine. It helps if you let the engine idle for few seconds before you take off. This problems doesn't go away by itself. You need to turn off the bike, start and let it idle a while. After that it works again.

Is this anywhere near what you are experiencing?

You can set the idle all the way to 1250 and the bike still runs fine.
As far as the idling going up by itself, start with the idle controler reset and a cable adjustment through Tuneecu. Only after that, check tps.
Fwiw

Precisely!

Sounds like a Tune Ecu cable is in order.

BTW, can i adjust the idle speed mechanically, or is it just through electronics?

Electronic idle control. You can set the speed in Tuneecu. There is no mechanical adjuster.

It runs but at least on my bike charging voltage drops from over 14 V to near 12 V. I was a bit worried that it was actually discharging my battery when idling so low. I didn't get blinking oil light but one question is what kind of rpm does the oil pump need to work properly?

I still get 13.7v at that rpm. I get 14.7 at 1450rpm
Your regulator might not like it indeed.

The oil pump is pushin enough oil in my opinion as the bike is turning over nicely still. Lots of 950s run at that rpm

I had worse problems than this past 2 years,including engine stopping,when i pull the clutch(cannot hold idle),idling 4000 all of a sudden and etc. After tried everything and feel desperate,i remember that i have aftermarket exhaust pipes which i am using them with stock map. I decided to change the map with Akra one,and guess what? All problems gone!

So if you have a slip-on,try to throw an aftermarket exhaust map if you are running with stock. My bike is also a 2006 btw.


Good luck.

Well, the weird idle problem was fixed with a new battery, the old had a bad connector (broken). Start fidling with TuneEcu and it is quite easy to work with.
