i bought a 97 cr 125 about 4 mths back and ive had nothing but trouble with it, for the first couple of rides it was flying but after that it wouldnt hit any bands. also fuel was pouring from the over flow on the carb.

I sorted the carb problem by changing the float and fuel pin in the chamber as this was worn and was letting fuel leak into the chamber. This evening ive been playing around with it again and it still wont rev out in any gear. Im using a 9 plug but have also tried a 8 and 7. Tonight i got hold of a different coil and lead and also the cdi thing but still no joy

any susgestions as its realy getting on my tits, just want to get it running sweet so i can sell it. Its starts fine first kick with the choke but once its warmed up a litle and the chokes in its jujst wank.

im sure its electrical and not fuel, any help appreciated

by the sounds of it mate, it seems like a blocked jet or shit in the carb.
strip the carb right down and get a air line blown through every hole

 

thanks for the above mate, went down there again and fuck me ive fixed it

cleaned the reeds as one didnt seem to be seating right, also found that the rotar and pick up where a little rusty cleaned them up, new plug

and shes flying
