So I've been working on my bike for the past 2 weeks changing the cooling fluid, rebuilding the petcock, painting my exhaust pipes, replacing my long gone air filter, and adjusting the valves twice. Last week when I went and adjusted the valves once more I put the bike back together again. After riding it a bit with the petcock set on the "OFF" position, I noticed the drop in RPM and stuttering of the bike that happens when it's in that so I switched it back to on. I drove around for about half a minute when my bike started to lose power and began to dump gas out of the overflow tube.

So I've been able to run my ninja as if it were new when it's set into off but as soon as I put it on the "on" setting it just dumps gas out. Any ideas on what it could be? Something is causing too much fuel to enter my carbs but I have no idea what it could be.

This only happened after I adjusted the valves, but I don't think that's the cause of it.
