A few months back my dad let me have his Bayou 400. It is a great bike and ran fine for a couple of months. It never had a great idle, but once it warmed up it was ok. Well, a few months back i was riding it and all of a sudden it shut down for no reason. I ended up having to push it back to the house, but the next day it cranked up and ran for a few minutes, but killed shortly after. Now it won't crank at all. I replaced the spark plug and i actually left it out of the head and tried cranking it. It gets fire to the plug. I then removed the air cleaner and sprayed starter fluid and it ran for a couple of seconds and then died. i looked for a fuel filter and i haven't had much success. Does this bike have a fuel filter? and if so, where is it located? Any other idea on what the problem could be? It surely seems to be a fuel problem. Thanks for any input.
