Hi guys. I just bought a 2000 WR400F. It's popping a lot on decel. I ride with a friend who has the same bike and his doesn't pop at all. I checked the exhasust, it's all tight. From a search on here it sounds like I need to back out the fuel screw. Is this the same as the pilot screw? Where exactly is this and can I get to it without taking the carb apart? :think: Thanks for any help and advice!
