Question Need help with Idle 990 Ad 2011

Need some help with my 990 Ad 2011

Some time ago started to have problems with not having engine break on deceleration, took longer to the RPM to lower to idle.

Now changed spark plugs, clean filter, changed fuel pump filters clean throttle bodies, changed fluids, adjusted throttle cable using TuneEcu and checked TPS and other things and everything looks normal.

Now it is worse: when I start the bike the idle goes to 2000 rps and stays there for like 10 seconds and slowly goes to normal and riding in low speed is ruff.

Any help I appreciate, I am not a mechanic guru, but learning to keep my beast fit.

Did you adjust the throttle cables properly?, the cables is the most likely culprit if the TPS voltage is correct.

Thanks for the tip, I will try to check it again using TuneEcu to position the motor.

Any help is appreciated!!

Here is the video of the Idle:

Does it do it every time it is started? What was your TPS voltage (hot), when the engine is hot what is the throttle cable slack like.

You could try backing both cables off so you have more freeplay and see if it still does it.

Only other thing I can think of is air leak, what is the pressure sensors reading when the engine is running.

Thanks NKL!

After reading your suggestions I went back to the bike and did the follow:

Connect TunEcu
Tested everything and everything was ok
Parked the motor to adjust the throttle cable
Reset adaptations via TuneEcu

And voile it is a miracle! Bike is running fine.

I guess the adaptation reset was the missing thing.

Thanks again NKL for the suggestions.

No problem, glad you got it sorted, these sorts of problems are usually something simple.

Idle speed

Should be TPS adjustment. You need to adjust it with trial and error, not 0.55V is good for all, Rottweiller filter needs higher TPS voltage. If it changes when adjusted, could even be worn. What is the milliage?

Hi Gefr,

My bike is a Ad 2011 with 30 K miles on it.

My filter is a BMC and my bike has a Remus Roxy setup

It is running fine now and if I have this problem again I will try your suggestion, thanks.

Carlos
