I had 2 gas leaks on my 1998 Honda ST1100 in last 12 moths. Only when the engine is on. When turn off it stops. Both times happened after sitting in my garage for couple of weeks. And both times, while waiting for friend to help me, after couple of weeks, it "fixes" itself. I tried to find what's causing the leak but after gas evaporates it's hard to follow the trail. I'm assuming one (or more) of floats gets stuck while sitting in the garage. And I'm assuming I have to take off the carbs and clean them. Since taking the carbs off is PITA, I wonder what else can cause the problem?

Thanks for any help, Afan
