I started my bike up one night, the next morning I come to see it and there's a massive pool of gas underneath it. The tank had drained. My bike was in semi storage for 5 months. I talked to BK, they said that a sediment buildup in my float bowls probably caused the fuel needles to stay open, overflowing the carbs. They suggested emptying the float bowls and fuel system.
Up to this point, my only problem was gas leakage, when I added a tiny bit of gas, the bike purred like a kitten. Then I filled the tank completely to take it to a friend's garage for the drainage. The result was two cylinders (of four) shutting down completely. Thinking about the problem, I believe what happened was that two cylinders were the ones with fuel needle problems, and so were constantly being flooded by the fuel that was probably just pouring in. If that's the case, then BK's solution should still work.
Question 1: do I have more serious problems than sediment build up in my float bowls, and do I hence have more serious and possibly costly repairs waiting for me?
Question 2: do I need to worry about screwing up my carbs and having to resynch them afterwards when I'm performing the drainage? While I'd love to learn how to synch my carbs, I don't have the equipment to do it myself or the cash to pay for someone else to do it for me.
Any help/advice is much appreciated. I wouldn't harrass you guys for this, except I want to fix it today (Sunday) and BK is closed so I can't harrass them for advice.
Thank you kind sirs and mada'ams.
