Another question for the pros
I rebuilt a 2001 400 ex including valves , timing chain , tensioner piston and rings. Well i got her all back together and she fired right up. I ran a few heat cycles with no issues until yesterday. but now it will fire up and idle but when I roll the throttle she starts to backfire and die. I cleaned the carb during the rebuild so I don't think that's the issue. What should I look at first?
Thanks for any advise
