Hi, Had a few issues with my bike during a ride today. So after getting back, I decided to drain the fuel from the float bowl to be sure there was no water causing the issues. My bikes a a 2006 suzuki intruder vl250. The bikes got a vacuum type petcock/fuel pump. But as it turns out, the float bowl just dumps fuel for as long as the drain valve is open, at least half a litre or more(with the bike off) and it just keeps going. Where should I start? And how do I test the vacuum is working?
