Throttle Stuck...

[Fred W]

Fred W, Any good way to look at that area with out fully taking things apart.. I'm mechanically inclined enough to know how mechanically inclined I am, and I'm not that mechanically inclined.

Not sure, but maybe the easiest way would be to pull the air filter and use one of those inspection "mirror on a stick" things to peer into the throttle bodies?

I was suspecting and hoping for critter crap, but that noise and popping points towards what Howie said.

Good luck, keep us posted.

I called my local Yamaha Dealer, they will pick it up for $35, and he said "With under 20000 mi its not the cam chain." The working quote is $250 for removing any debris from the intake and checking the cam chain which I insisted upon. He seems to think its not necessary. I told them not to start it or turn it over till it has been checked and put a piece of masking tape over the ignition marked "DO NOT START" they have to remove the tape to start it. They pick it up tomorrow.

They may think you're the biggest, uninformed dork in the universe, but eff-em....it's YOUR bike and you're doing what's smart, even if you've been inspired by some pisswhistle alarmist from Florida.

FYI, there IS historical record of cam chains getting noisy under 20K on this forum. I've found 'em before, but screw it, I'm goin' home. I'll look later.

Ask them for a written guarantee that there's nothing wrong with the chain or CCT, even after inspection.

You can't see the throttle bodies from the air filter compartment. Intake tubes are too long and a bit curved. Airbox needs to come off to look at the throttle plates.

As for sticky throttle return, I had my cables cinched up just a bit too tightly at one time, the return action was very slow, although I had no trouble forcing the throttle closed by twisting the grip. It would bind enough the spring couldn't close it sometimes. Used the adjuster in the cable to add just a bit of length.

If the throttle is staying open when the grip is closed, I suspect mechanical interference (badly set cruise control bead chain, something jammed in a throttle body, gummed up throttle shaft) or a return cable removed (no positive closing action from the grip.)

Fuk.....I can't wait for you to get that scoot fixed

Still no call.. Either its so messed up they are trying to figure out how to break it to me gently... or they haven't got to it yet.

With all the throttle spring unwinding reported on this forum, just wondering what happens warranty wise etc. if a dealer notices it was done, esp. with a stuck throttle reported. :blink:

 

[Fred W]

The spring has nothing to do with any throttle being stuck open. Our bikes have two throttle cables, one to pull the throttle open and another to pull it shut. You could have no spring on it at all and you should still be able to close the throttle fully with no problem.

So the verdict is in and so is the bill. Turns out there where two little critters, one behind the seat and a second in the air filter... when I reached in and pulled the air filter it ran the only way it could, into the throttle bodies. Where after replacing with a new filter it was trapped. After my ride into work it was well cooked, and then on the ride home it got sucked further into the butterfly valves propping one open. My actions (closing the throttle hard) nearly cut it in two. :blink: I wish I could have gotten pics.

The price... $172.10. Not bad, oh well.

They found no problem with the cam chain, or the tensioner. :yahoo: (That's good.) And the running was bad due to the .. well mouse in the works.

My baby is back. B)

 

[Fred W]

Ah... baby mice.

You can't run your bike on them...

(PS - fix your sig. we don't do the pix in the sig thing here)

But I can try, maybe cheaper then gas...some how.

(PS Sig fixed thanks for the heads up.)
