help guys! is this broken? and is the O ring in the right place. My bike keeps revving around 2-3k RPM on idle.and everytime I rev it shows the engine check light also. I have not done any mods or anything it's all stock. any advice would be great. I can't sync the carbs also because it revs too high.

I keep seeing error 14 also

I just looked up the parts diagram, Yamaha calls that part a "stepping motor". I have no idea what that does? Based on the diagram, the o-ring is in the correct spot. That part is $112 USD. If it were me, I'd clean up both that part & the hole it goes in. It looks pretty dirty to me? After that, coat the part/o-ring with grease to lubricate/seal the o-ring. If that doesn't make the error code go away, it may need to be replaced. Like I said earlier, I have no idea what a "stepping motor" is, or if that would cause the idling problems/code 14????

Based on the "Code 14", my interpretation is that a "hose" is kinked, or plugged.... That part in your picture doesn't like a hose? It looks like an electrical component. Being that Yamaha calls it a "stepping motor" leads me to believe this part is most likely NOT the source of your problem....

didn't know I hade to apply some lube to it will give it a try and will clean the port also

I have heard of other bikes idling high when there is an air leak somewhere, where the engine can breath after the AIT (air intake temp) sensor. I can't remember the exact trick, I think they sprayed something to see if the rpms would jump, suggesting where the leak is.

How would I be able to solve it ?

That is a common way to regulate the idle on fuel injected vehicles. Clean it up and make sure the O-ring is not damaged.

I did clean up and the o ring is not damaged but the O ring is a bit too tight atm. can that cause problem? it sits there but it took me some time to put it there since its too tight but it sits there with no problem.
