I just recently bought this random pit bike that is crf 50 plastic and I believe frame based, and actually has alot of good upgrades that are mentioned in my profile if you care. My problem is that it falls on its face mostly from closed to about 1/2 throttle depending on the gear I am in but this is my winter project but I would love to get it decently responsive before winter. Any help on a possible upgrade to maybe a namebrand carburetor of bigger size or any knowledge of any of you who know about this bike would be awesome. It is supposedly a 125cc motor with a K(*)F brand carburetor. I am a member of thumpertalk and have a yz250f but when it comes to this i have no idea where to start as a newbie on here so thank you to all who are willing to help, Thanks!

I have 2 pics posted in my album now and if anybody thats tryin to help could use some more up-close shots of the bike then just let me know. Thanks to all!

very sweet yz's man

the 22mm mikuni (china type) work very well on these 125cc pitbikes
but first i would loose the paper air filter and get a dual stage foam like a tb or unit
the paper filters get packed with dust quickly and that may be your bog issue
also check your plug to see how its looking

Mess with your needle and set your fuel screw to 1 1/2 turns out.

leave the needle in the midle to start and then if not good move the ring down to move the needle up.

alright, the filter sounds like its breathing pretty good and i will clean it enough so that it shouldnt get packed. I really like the look of those filters instead of the foam ones and arent those foam ones really bulky, i would think i would get filter oil all over my leg with one of those? Thanks for the sugg, i have actually looked at a 22mm mikuni but i wasnt sure what size would be good for my bike, thanks
