Sticky throttle??

7380 Views 8 Replies 6 Participants Last post by  wheelsquad
I have a 2011 Grizzly 700 and the idle remains high when I let go of the throttle. Early on when the problem 1st appeared I could goose the and get it to step back down. T can not shift the gear shift lever while the revs at high so I turn the engine off to shift. Where do I start to look for this hang up?
Thanks

Start by adjusting your throttle cable on the handlebar side. Adjust so there is just a hint of movement in the throttle before rpms rise. You can look through your diagnostic pages to D01 to check your throttle position.

Check your throttle cable routing as well. Make sure nothing is pulling on it, and also make sure nothing is squeezing or pinching it. Check at all handlebar turn angles.
It may be you caught the cable on a branch and it has been pulled and is holding the throttle open. Trace the cable down from the throttle housing and make sure it has not been pulled tight.

A sticky throttle can get you in trouble fast. It is best to make absolutely sure there are no problems.

I think you should be safe and make sure the cable and the throttle itself are free.
Go ahead and take the cover off the throttle, loosen the cable and remove it from the throttle cam.
Make sure the throttle is smooth and effortless when pressing the thumb lever. Now would be a good time to clean and lube with light oil.
Make sure the throttle cable is loose in the housing. When they get worn or dirty the cable will stick in the housing and be hard to move. You may have to take it loose on both ends to make sure, a pain as it is at the throttle bocy. If it is hard to move you may consider getting a new one.
From your explanation regarding letting the thumb lever snap back, it sounds like something may be dirty and tight in the throttle.

It may just be out of adjustment, but usually the cable pulls a little when you rotate the bars from left to right. If it does not change rpm when rotating lock to lock, it probably is the cable or throttle dirty.

Good Ideas. now I have a starting point

X2 Great advice. More than one member has shot through a garage door or garden wall because of stuck thottles.
While your doing all these checks oil your cable as well.
Finally figure out the problem after a long time without out any issues. The point where the throttle lever assembly and cable connect is broken. How difficult a job is it to replace the assembly and the throttle cable? Any special tools of tricks to get this done? This bike has never been into a Yamaha shop yet so I have no idea the labor cost. Parts are approx $170 at babbitts

I have a brand new thumb throttle assembly off a 2011 450. No 4wd switch on it though cause I kept that. PM me if interested, I'll sell it cheap. Just need to verify it will fit. I know it isn't exact same assembly part number, but pretty sure it would still work. But I will verify.
