Throttle sticking

[jriley43]

Last weekend I went riding with a few friends of mine. Anytime I went through a whoop section or hit a rocky section at mid throttle or higher my throttle would get stuck open. Each time it did it I would pull the clutch in and romp on the throttle, which would free up my throttle. I have taken my carb. out to see if maybe the slide was sticking on something, but have not found anything that would cause it to get stuck. Also checked the throttle cable, and it was working properly. (I went ahead and oiled the cable) Is there something else that I am missing that would give me this problem.

Broken slide return spring? Cable frayed inside the housing? Pulley binding in the throttle housing?

if none of that works - check your throttle tube/grips - grip could be binding on bark busters (if you have them...)

Depending on the cable routing - you can also have the cable pull out of the adjuster and hang up on it. Safety wire cable to adjusters at each end of throttle cable to avoid this issue.

Needle jamming in nozzle from sand/dirt in float bowl. It doesn't take much.

Check the routing first since its the easiest. Give a yank on the cable and see if anything happens and make sure there is some slack. I stuck a bottle of water behind my headlight once and it caused it to rev up out of control.

What was the outside air temp. and humidity ? Carbs. can ice up when the air temp. is above freezing.
Wrapping the carb. in bubble wrap, or something, is a quick fix for cold weather riding. Even better is to channel warm air from the engine.

I'd go with this one .. my 06 300 had a bad habit of going wfo through whoops if I had gone through deep water before hand. It did this two or three times on me. Take alook at your slide and see if you notice and scoring or scratches. Take a look at the needle same deal. My slide had a few scratches but my needle had evidence of much more. Put filter kit from kevins racing on your carb vent lines.

May look into those filters.
