Sounds normal for when it's cold.. Is that when it's happening or does it do this to you hot as well? If so, I'm clueless.

 

Well OLDMAN this happens when it's already warmed up also. It can do it when it feels like it, even after 30 mins of riding. And it doesn't discriminate on outside temps either, cold day or beautiful sunny days it does it just the same.

 

How long does "it" usually feel like ideling at higher RPM? Does it affect performance in any way?

 

It will idle up when cold. It is also normal for it to idle up briefly after restarting a hot engine. Be sure your throttle cable has a little free play. Use the adjustment in the cable just below the twist grip. If its still runnig fast at idle at other times try disconnecting the Cobra thing & see if it returns to normal.

 

have you done anything to, or in the vicinity of your throttle bodies?

 

Maybe something is sticking or binding at times?

 

I don't have any problems like that with the Fi2000. See if it persists for an extended period of time.

 

FRED it usually lasts the whole time I'm at a red light. Doesn't seem to be afftecting performance any it still accelerates when I gun it.

THE EDITOR my throttle bodies are untouched. What's a throttle body? (I haven't touched anything in reference to performance in some time now. The only performance tinkering was the COBRA Fi2004, but I installed that a year ago. The only thing I have messed with was the idle screw under the seat to see if it was this. It seems to work fine, I can lower and raise it without problem.)

MUSTANG I've had this problem for about 3 weeks now. It does this spiking thing every time I ride it, on average of 4 to 5 days a week.

CHURCHKEY I'll try the adjustment knob you are refering to and see what happens. Trying to rev the engine doesnt work either cause it goes back to the 1300+ - rpm range, even after its warmed up.

CAMEL maybe your right. But that's the million dollar question, what is that something that is sticking?

 

Upon further review----
Could be the LCV hanging open or if your riding in cold temps the oil is not getting hot enough to shut the LCV down. LCV is operational untill the oil temp reaches about 178*. LCV controls cold idle speed. Just to check it locate the large 1/2" ID hose that goes to the center port of the LCV & plug it. OR unplug the electrical connector to the LCV.

 

I bet its a lose wire. Check all your connections I had somthing like this with my pc111 but once I solderd the connections pr. Frankenstine the problem disappeared.

Set the Fi2000 back the same factory settings it came with. (If you have move the pots at all). It came preset for the Warrior that has pipes installed already. Also, maybe unhook the module and see if there is a difference. I really think it's something else that's causing this rise and fall of the rpm's.

 

Well.. throttle bodies are the intake part that controls air-flow.
If there is a leak at that point the idle will rev and drop.
especially if your airfilter(s)IS(are) clogged.

 

thank you guys for all your input. I will print this page out and try all of your suggestions.
thanks again.
