So it was finally warm enough to get out and ride yesterday other than just to commute. Anyway, Im riding along and everything is fine and then I let off the throttle to slow down and it feels/sounds like the throttle is still slightly open, so i try and make sure the throttle isn't stuck on the bar end or anything by pushing it forward manually...still no luck. It's only doing this every now and then and its very annoying. I just rode 5 miles to work and it didn't do it once. I thought it might be the PCV i put in so I checked the throttle position calibration and re-calibrated, but it's still doing it.
Thoughts?

So even if you manually close the throttle, it still sounds like its open slightly? When was the last time you lubed your cables?

Also, where in Kentucky are you located? I'm in Lex and Richmond all the time.

Make sure they are lubed for sure. Have you recently changed them or pulled the gas tank? When I replaced mine, I had one line get pinched and it did the same thing with the throttle depending on the handle bar position.

Make sure the grip isn't dragging against the kill switch housing. Mine got pushed past the little lip that is supposed to keep the grip in place and would hold the throttle almost like ghetto cruise control.

Do you notice it more when the bars are turned to one side or the other? Try adding some free play to your throttle.

Check to make sure nothing is pinching the cables and that something isn't blocking the throttle bodies from closing all the way. After that, I'm out of ideas unless theres a detail I'm missing.

When did this problem start occurring? What mods do you have done? How many miles on the bike?

Just throwing ideas out there, but it might be an issue at your throttle body. Maybe the cable is getting caught on something, or the throttle body is getting stuck somehow. Just take the airbox off and check.
I don't know what it could be other than the cables, the throttle itself, or the throttle body.

Yeah, Im having a friend help me do a full teardown this weekend, just trying to get ideas for when we start.
Bike has 13k miles on it.
Umm. K&N filter, PCV, Leo Vince SBK Evo II slip on, IRC...probably all the relevant mods I can think of.

None of that could cause it to stick open I don't think. Clean your air filter for good measure. What I was wondering is if you have stock throttle tubes and/or a quick turn throttle kit that you maybe didn't realize was on there. Could be a bad install in that case.

Ya that's very possible. The ends of the cable are pretty much the same, but the end at the bars have the angled piece. The throttle body end is just straight. Usually if you lube the cables, you take them all the way off and force lube in one end, out the other to flush crap out.

What are you guys using to lube your cables?

When you roll off does it feel like it's sticking for just a second then drop off? Or does it stay like that for a ehile

I have never lubed my cables, and they are actually coated with teflon from the factory I believe. But any kind of thin lubricant that doesn't cake on would work. Silicone spray or lithium grease in a spray can maybe? And no to WD-40.

The reason I asked is because you shouldn't use any wet lubes on your cables. They will gunk up and get sticky. Dry graphite lube is the one to use. Though replacing them is the best solution

I have a spare set of cables I got with my bike so I never planned on lubing them. I was just going to replace them next time I was at the throttle bodies. Which is going to be this summer seeing as I crashed and need to do some tear down.

Where does one get dry graphite lube? I've heard that recommended before but never had luck finding it.
