I just bought a 400 2 stroke xplorer. When i was buying it off the guy, he discovered the solenoid was done and i would need to pull start it. On my first ride, 5 minutes in it starts acting funny like its not getting fuel and then stalls. It doesnt start back up right away but after a couple minutes it starts. I start off again and about 5 minutes later it does the same thing. This time though, it doesnt start for me again for 45 minutes. I talked to the guy i purchased it off and he said its never happened to him. I believe him. I checked the fuel filter, its fine. Someone suggested it could be to do with the solenoid, but that doesnt make sense to me. Any ideas?
