so at first i had a old messed up throttle cable and idle cable so i changed both and put brand new ones. its all good it rolls on really nice. but now when i close the throttle it manually closes because my hand makes it but the rpms are still up and are really slow on making there way back to idle. but dont forget the throttle is already closed on the hand grip but not in the throttle body. so what is the problem messed up spring or what?? im eager to learn! | ||

It could be as simple as having the idle set a tad to high or it may be something in the fuel maps. I am sure you did a tps reset after changing the throttle cable? | ||

A TPS reset isn't a cureall...for anything but a maladjusted TPS...! I've had the throttle body off, the injectors out, play'd with the ECMSpy for MANY adjustments...and what to behold....the TPS setting in the ECMSpy screen...STILL says 5.1...and the engine still runs just fine. Of course...for what it may be worth... Mike | ||

If you replace a worn/stretched throttle cable with a new cable then the position of the butterfly will change therefore throwing the "throttle position sensor" off. | ||

Throttle cables should have zero effect on the TPS setting. Resetting the TPS simply zeros the sensor to the throttle plate. The cable simply controls the opening of the throttle plate. It certainly wont hurt to reset the TPS, but it sounds like the idle is slightly on the high side. Mine does this if I don't set the idle at the low end of the spec. Having said all that the TPS should be reset as part of scheduled maintenance. | ||

ok that makes alot of sense with the idle being to high and you guys are very right i did forget to do a tps reset. thats on my stupidity. but il do those and find out thanks alot. | ||

Set (reset) idle speed with engine at full operating temperature. | ||

I would check with the manual to see that you've got your throttle cable adjusted correctly. As Sifo said, the throttle technically doesn't have jack to do with the TPS. However, if you've got the throttle cable misadjusted, it could result in the throttle plate never closing 100 percent, resulting in an incorrect TPS reset, because no matter how much you back out the idle adjust, the throttle plate never completely closes, thus no true '0' reset. The resulting flawed TPS reset could make your bike run like poop. If your throttle is adjusted correctly per the manual, there should be a smidge of slack which would allow your throttle plate to close completely with the idle adjustment sufficiently backed out.

My statement is still correct, but as noted, you have to know where the original setting of the idle speed cable was. The throttle cables have no effect, it's just along for the ride at this point..! The TPS...at idle has no adjusting contact with the throttle cables, only the idle cable. Mike | ||

ok i think im just going to reset my idle as well to get it all even and straightened out. and then do the tps with that and hopefully it all smooths out from there. | ||

You have to adjust your idle AFTER doing the TPS reset. As mentioned get it up to full temp first. |
