[QUOTE="grahamski, post: 1213271, member: 78974"] I have a 2001 CR 125 and it’s not running well. The bottom 1/4 to 1/2 of the throttle runs like a champ. When I get on it trying to accelerate and pull to over half throttle instead of screaming like it should zzzaaaAAAAAAAA... I get a zzzaaaa..aaa..aa..aaa..aa..aaa like it is cutting out and it never really reaches it's top end. This is my first dirt bike so I’m relatively new to tuning these things, but I was thinking this meant it was running to rich? So I should try a smaller main jet (larger main juet number) and/or moving the needle clip position up. Any other thoughts or suggestions? Thanks. [/QUOTE]
