Won't idle down

[steve_g]

Morning all...

Curious if anyone has any insight to a specific problem or if it has to be a shop fix...

The problem lies with a xb9r, lately the bike will no longer go into a high idle on start up, just a slow lob, but the problem also lies when slowing down. When the motor is warmed up or hot it takes upwards of 20 seconds to idle back down from highway revs. I did find a fractured cap on a hose barb off the draft tube, and repaired it but no change. The butterfly does close, I did make sure of that, other than that I'm at a loss.

Any ideas?

Thanks

Need to know what year to start with.

What ^ said.

My first reaction is - if it's an earlier bike, get a hold of ECMspy and check the throttle position voltage - could be something there.

tps reset should fix it

TPS and lube that throttle cable

Lube does an engine good [up]. My cable caused my bike idle down slow 'til i lubed it.

Sorry 2003, and all the cable operate with out hanging up

Like ^he^ linked, it could be an intake leak. But first quick thing to try is adjusting idle down below 1000 RPM after the bike is up to operating temp. - then ride and see how goes.
