Why is it that every time my bike sits for a month or more the pilot jet gets clogged and I have to take the carb out and replace it. I try to drain the fuel out if it if I think it is going to sit for a while. But some times I don't, thinking I'm going to ride it again soon. Then next time I start it up the bike won't stay at an idle without dying. Is there any thing I am doing wrong or is there and easier fix then yanking out the whole carb every time I get lazy and don't drain the gas. Frustrated DRZ owner.
