hi all i have a 2004 cr125r that im trying to tune up so its super crisp on the gas
i have just put a 400 main 40 pilot 69 needle and 3rd clip and 2 screw out on air/fuel
but it dose not seem to the pull like i would like it to
the only mods to the engine is a full Dep exahust system and Vforce3 reeds and cage
what are your thoughts on jetting for this bike

Get that piece of shit carb tossed out and install a pwk air striker screw top.

The girls ran after my bike with it installed like they run after brats in the club. felt like Ronnie mac cool

(Do a search, even I have a jetting thread started regarding cr125)
