Intermittent sticking throttle

[bt's shee]

I have installed the tors removal / idle kit and checked the carbs three times for problems, but I cannot find out what is causing the throttle to stick. I have a brand new toomey cable, new mains (for fatties), new carb screws, and have gone as far as setting the idle screw so that it doesn't interfere with the slides. During the tors kit install, I beveled the idle screw hole in the carb ID and checked it several times for burrs /deformation, everything. This is on a 2004 Banshee LE.

 

The thumb switch come back to its rest position, wiggling the cable doesn't fix the stick, tapping the carbs deosn't seem to help (but I am usually riding in a flat field 3/4 the way through 2nd or 3rd when I fiddling with it), and the slides still have the black carbon layer on them, with no real scuffs except near the mouth of the taper.

 

The only thing I can think is that the little guide in the wall of the slide tunnel got tweaked a little and is causing the carb to hang up.

 

Any advice would be great.

 

Thanks

i pulled the slides out adn took some scotch brite or fine sand paper and cleaned the edge up the casting of the bottom of the slide. there was a burr and it would stick.

 

after clean up the slide it worked great. never had a problem since

 

 

might give it a try

Slide polish trick didn't seem to help.

 

At WOT, shoiuld the slides by topped out in the carb, or should you be able to see some amount of the slide when the thumb throttle is in the WOT position?? Maybe I am jamming the slides into the top of the carbs. Rigth now, you can see just a bit (1/16") of the slide bottom when the throttle is pinned.

 

Thanks

at wot you should see the bottom of the slide in the bore. you might need to adjust the cables and stuff better

I took the bansh out today with the seat / air box lid / filter removed and watched the slides using a mirror while I rode. It turns out the right side is the only side sticking, and it is hung about 1/2 way up. I polished all of the sharp edges of each slide before riding today, and it helped a little.

 

Nothin like sittin on the grab bar with the throttle in one hand and a mirror in the other on a bike that has a sticky throttle. I got a couple wheelies out of it.....

 

The slide alignment pin in the right carb seem to have rough edges, and I think I know why. During the carb assembly after installing the TORS removal kit, I put the #$@% slides in backwards and ran it for a minute, unitl I figured oout my dumass mistake. Chances are, this caused the slides to bang around inside the carbs and chunk up some of the smooth surfaces.

 

How do you remove the alignment pins from the carb? It looks like there is a flathead slot in the outside of the pin. I tried to turn it, but it didn't go, and I stopped before I tore it up.

 

Thanks for the help...

Swapped out the slide on the right side with one that had the black polished off and it stopped sticking...

I had the same problem when I installed the TORS eliminator kit. What is going on is the slides are being pulled up too far and getitng stuck in the rubber gasket between the carb and top. Adjust the cables so that the slides do not pull up so far and the problem will be solved.
