Sticking Throttle

[boppa]

Seems my throttle is sticking (won't return closed when released ). Any ideas where to start looking for root cause of the problem? TIA, boppa

First of all....more info......year of bike, condition of cables.......if they are old and ugly get new ones.  Did you recently do anything to the contols on the handlebars?  If so you probably have the sleeve cocked in the switch housing.  have you rerouted the cables either on purpose or on accident?

2000 I/S. Cables seem to be in good shape. Nothing done to bike. Just started sticking on the way back from Inzane.

My IS throttle sticks when I have the bars turned all the way to one side or the other. Alph's does as well even after replacing the cables. My Standard never did this, but I assumed it to be normal for some sticking on the IS.

It sounds like yours is much worse than mine though. Try lubing the cables.

On the throttle there are two phillip head screws you can access on the bottom of the throttle housing on the handlebars.

Take them loose and out and carefully lift the top cover off, it'll have wires and the switch in the cover but you can lift it enough to see the internal cables where they emerge from the cable exterior right there in the bottom half of the assembly.

Do nothing but shoot some oil onto the inner cables and work the throttle easily while holding the bottom half from moving.

You ought to find that will significantly ease up the movement and allow the throttle to work as designed.

I suggest to not do anything else until you first do this little step.

Following that I would suggest to get a can of spray silicone and spray the whole linkage under the tank, both side with generous amounts of the spray. Don't be hesitant but spray a lot while turning the throttle a bunch of times.

I also caution you to not force the throttle at the end stops. There is no need to do that and it can cause more problems than you would want to address.

Thanks for the suggestions I'll give them a try and see what happens.

It can also be as simple as grip glue/RTV sealant and/or tape you put on the throttle sleeve getting old and bunched-up between the throttle sleeve and throttle grip.

My throttle stuck when I got my bike a few years ago. I lubed it with some good lube and it has
rocked ever since...

I couldn't get enough slack in my throttle cables to get the ends out of the grip-twist, so I asked
around here... a trick is to loosen the handlebar riser clamps (while protecting the tank - the bars
want to swoosh down and put a dent in your tank when you take the last riser bolt loose) and
push the bars to the left - then there's plenty of slack.

I put lube down the cables until it started coming out the carb end, dripping onto the motor.
Careful about your lube choice... I figure if you use WD40, it be great at first, but you'd have to
redo it soon. When we did my buddy Gary's cables, all he had was silicone spray, it didn't work all
that well even at first... This TriFlow is good stuff, and there's plenty of other good stuff...

Has anyone used graphite? I'd think that would do the job, though it might be a bit messy.
