You need to look at the carb and fuel pump. I had an SRV, but I don't remember what type of carb is on it. Anyway, either the pump is leaking fuel back down the impulse line back to the engine, or the carb is not sealing itself off from the pump to stop fuel from flowing into it. If this situation becomes worse, you may hydrolock your engine and cause a much bigger problem.

If this were a Mikuni carb (I am almost positive it is not, I think it's a Keihen (sp?)), I would recommend a new needle and seat. As I can't remember the SRV setup, I just recommend finding a rebuild kit for the pump and carb.
