I have a stock 2004 YFZ450 with a HMF pipe. Bike runs great but there’s been several times where the bike will shutoff when popping a wheelie. In order for it to turn back on I have to wait like 20 min before it turns on again. You can hear the bike trying to turning like it’s about to turn on but it won’t. Seems like if the motor gets flooded or something I’m not sure. Bike had always ran on 93 fuel so the fuel isn’t the issue. Does anyone have an idea of what it can be?
