Unhappy sticky throttle

I pretty much have this problem since I got my bike.

Picture this:
  • I am slowly opening up the throttle one degree at a time.
  • I get up to 5% - this is the slack in the throttle.. there is no tension
  • From 5 to 15% - there is pressure back from the throttle, but nothing happens
  • Somewhere between 15% and 25%, suddenly gas is given to the bike, and the bike kicks forward.
  • This happens in ALL gears
  • The jump is ONLY at the start. Once I get past the 25% mark, I can take her all the way up to 100%, and there is no jump (other than when the powerband transitions in)

There is no smoothness to starting the bike or changing gears.

My setup is:
  • 2009 ZX10R
  • No Engine Mods
  • Power Commander
  • Ignition Module
  • Sprocket changed for higher performance
  • Timing Retarder

How the heck do I fix this? I would definitely love s smoother ride.

It maybe obvious but have you tried twisting the throttle adjustment on the cable? When I flipped the clip-ons and did the ziptie mod to the throttle, it stuck but both times playing with the adjuster fixed it.

I'll go out on a limb here and say you need to check the cables - I.E. the routing, the condition of them, the connection and orientation of them in the throttle housing around the throttle tube, etc, etc. Check everything related to the cables. And while you have the housing apart and the cables disconnected, check the throttle tube to be sure it's not interfering or hanging up on anything.

I may not be perfect, but at least I don't ride a Suzuki.

Scary stuff. I know of a guy on a R1 whose throttle go stuck on the track. He jumped off and the bike killed a corner worker. Throttle not snapping back is very dangerous.

Been chasing this issue sort of on my Gen 2 too.
Haven't did any real diagnosis cause it is really intermittent. It is a bit unsettling though not knowing if it's gonna stick or not, mine stuck at 5K and up for maybe the first two rides after the rebuild.

I've been on a few rides since then and it hasn't done it, from the looks my cables are routed correctly, I may throw new cables in when I get the money.

If you fix yours or find the culprit be sure to let us know!

Whoa. Yes, it is very dangerous! But the action of that rider is borderline criminal IMO. If the throttle sticks and you feel out of control with it, then you use your right thumb to hit the red kill switch to the "up" position, puol the clutch lever in, and safely coast to a safe and complete stop - and while in control of the bike. I find it almost impossible to think of any scenario where deliberately getting off the bike is a better option. The only one I can think of is if you're headed for the edge of a cliff.

But to your first point, I agree that this is a serious concern and it should be addressed right quick and not ridden until it's been corrected. Don't fuck around with this like you state!!!

Don't "look" at it, check them. I've seen it more that one time where the push-pull cables come off the throttle tube cam where they connect and get pinched between the tube and the inner housing inside. You can't see that externally and can cause it to bind up and overcome the return spring. This requires you to roll the throttle off manually to overcome it over-wise the throttle will stay open when it shouldn't.

I'm glad it's not a reoccurring issue with yours, but you should be diligent in checking everything out and keep a good head about you and what to do should it happen again.

@or10r; Yes, although I didn't remember his nick name. I just remember hearing people talk about it and it kinda stuck with me. Do you know any particulars other than the rider jumped off before turn 9?
