300ex over flow valve

[b0rn c0nfused]

So I'm getting tired of spilling gas ever time I wheelie or load my wheeler into the truck. I blocked off both lines coming out of the carb and it wouldn't start. If I only block off 1 line it will run but it bogs out when I slow down. Any ideas of how to block off the over flow valve and still keep the wheeler running?

Hi

try to find supermoto spill bottle, catch can, etc.... when racing, they need to make sure that no fluid will be drop on the paved section of the track, so they have these device.

You can use old baby bottle.

Good luck!
