I have a 2005 CRF250X that was sitting for about 3 years. Over the weekend I removed the carb and cleaned all the jets. After putting it all back together, the bike started right up and ran just fine. Upon shutting the bike off is when the problems started.
With the BIKE OFF and the gas on RES, gas to pouring out of the overflow line without stopping.
With the BIKE OFF and the gas on ON, gas will pour out of the overflow for a second and stop.
With the BIKE OFF and gas OFF, nothing pours out...the way to should be.
I have never come across this problem nor have some people I talked too, so any help would be much appreciated.
