Title: Throttle gets stuck in wet conditions
Post by: Shadow on June 23, 2011, 11:21:19 AM
Pretty much what the topic says. Had forgotten the problem but now that the 125 works again got a reminder today while riding in the rain.

So, riding in wet conditions will make the throttle stick open eventually. Any ideas what might cause this and how to prevent it? The cable returns like it should, even when the throttle sticks, so I'm suspecting the slide but have no idea why or what could be done to it.

What type of pre-mix are you using?

Try checking/lubing your throttle cable. Look for the easy things first. :)

I can't help but think that somehow water is getting a direct shot at your carb slide through a leak in your airbox or something similar.

Thats what i was thinking.
I had a 98 CR 250 and the throttle used to stick on that every now and then and  worked out it was  a nut missing from where the air boot bolts on to the airbox....
After i fixed it i never had another pant staining moment that a stuck throttle can give you, good luck with it

Like I said, the cable doesn't seem to be a problem, the slide is more probable culprit. Any ideas for a good sealant to the carb top plate/where the cable is attached? Bonus points if it can be removed fairly easily for carb disassembly.

No bolts missing from the airboot, and it's sealed with silicone from the airbox side.
