My bike has the following disconcerting habit .....
If you ride through water deep enough to hear a change in the sound made by the air box ..... Shortly thereafter the throttle starts to hang up/stick. My bike does this any time I cross deep water. Fortunately its not that often. the last time was a few weeks back in the middle of an enduro. The lower carb vent lines are run down by the linkage,have a 45 degree slash cut and are slit. The upper carb vents go to the air box. I'm curious if anyone else has this issue when dealing with deep water?? Actually its not really that deep but evidently deep enough. The throttle will hang if you run it up onto pipe. When you lift off the throttle it won't snap back. Assuming you get the clutch in you can then work the throttle and it will come back down. If you keep off the pipe the throttle usually won't do anythign crazy but you might get a neat mid throttle cruise control thing going on sometimes. Whats really interesting is if you go through some whoops at a good clip shortly after the water crossing it will go wfo in a big way!! Something about the way the bike goes up and down really seems to set it off!!!
My first theory was some gunk was getting sucked in through the air box ... but the air filter should stop any debris. The other thought was water coming up the lower carb vent lines ... but that isn't suppose to happen if your running the others up to the air box right?? Not only that but is feels like the slide is getting hung up which would indicate grit .. which I doubt would make it through the jets. Or is it just water in the gas going thorugh the system causing alean wind it out conditions which make the slide hang? The other thought was gunk coming down the throttle cable into the slide area. However I can't say I have ever really found anything in the slide area.
The solution to the problem is to pull the carb and clean it. After that it usually runs fine.
My last cleaning I did find debris inside the float bowl drain catch thing. I did not really see anything in the slide area. The carb was such a bitch coming out that what debris I found in the venturi area probably came from removal. I checked the float height and it was about 8mm which I believe is about right. Ordered a new throttle cable.
anyone else have this problem. It is almost garaunteed that the throttle will start hanging if you run it through deep water. You can run all day in wet sloopy conditions and it won't miss a beat. But if its dry as a bone and you hit one semi deep crossing you better be fast with the clutch fingers for the rest of the ride.
