Slide p/n sticky throttle

[ucrtwf]

Bike 2010 ec300
Rb carb mod

When I. Go over whooped out trails my throttle sticks open. On the flats, everything is fine. A buddy said the slide should be replaced.
I've been looking, I can't find which one to buy. Jd jetting has some, but don't know which number to get. Any thoughts ?

Carb is clean.
It snaps back nicely unless it sticks of course and then a few panic whacks frees it up.
Cable isn't pinched.

Thanks

I'd pull the throttle tube apart, and make sure there aren't any little burs to hang up. I had a similar issue on my KX. Where the cable attaches at the the throttle tube...was a small bur that ocassionally hung the throttle wide open. It happened once, and I ignored it. Second time, same day...I field-stripped it finding a small bur on the plastic part the cable attaches to...No more hang-ups.

The number should be stamped on the bottom of the slide.. unless if it was recut by RB in which case they should be able to say what to. I'd be inspecting the slide. Wear will be visible. Also considering triple checking the cable retainer and clip, and also replacing the return spring.
