Hi all. My sons 2008 lt50 is running like crap. It will idle fine but has a bad bog(hesitation) at mid and full throttle. Took the carb off and gave it a good cleaning. Everything looked good in the carb but I still have the same problem. Quad has very very low hours and to the best of my knowledge has not been modified in any way. Thanks for any help in advance. Mike

 

Welcome to the forums Mike.
Is this the 2 stroke or 4 stroke model?

 

4 stroke

 

LTZ50...I'd prolly check the valve clearance. Maybe they need to be checked after break-in.
Nothing was in the main jet eh?

 

Jets were clean. I will check valves next. Bike only has about 5 or so hours on it though. Thanks
