Now that we airhead junkies got a place to play. My R100RT sports it's stock Bing carbs, and around the 100,000 mile mark it started snapping ether the main jet needle itself or the clip which holds it in the slide. Both carbs are doing this and I am only getting 2 - 3 K miles on each needle. Right now I am loosing one about every 1K because first it's one side, then it's the other. It's getting really old and I can't seem to find any answers, anyone know what's up? It's bad when you are preping for a weekend ride and you make sure you got two sets of needles and clips cause it's likly that you'll break more than one in two days.
