2002 cr125

turtlemann14 · 04-27-2008, 03:38 PM

scootertrash (he finally made an account)

has a cr125 from 02 that seems to have no power on the low end of the rpm
and has a good bit of power on the top end of the rpm range (but it still dose not feel right)
after it warms up it will die if you flick open the throttle

i think it needs a bigger pilot jet

is my assumption correct?

this bike has a new top and bottom end in it (less than 10 hrs on it)

does it bog at 1/2 throttle?

turtlemann14 · 04-27-2008, 06:46 PM

nope, only at the beginning when i fling the throttle wide open

so you think it running lean?

it revs fast when cold, but seems to have a little less power than it should

and i still don't see where it is marked on the pilot jet what size it is...

you should be able to adjust it with the air srew on the outside of the carb

turtlemann14 · 04-27-2008, 08:03 PM

i tried screwing it all the way in and it got a hair better but still bogged

gscx · 04-28-2008, 01:40 PM

it might have something in the pilot jet, or, if it is clear then you should move up a size

turtlemann14 · 04-28-2008, 02:08 PM

its clear... i cleaned it myself

how much do jets run?

and if i replace the pilot i have to re tune it all don't i?

if the mid range and top end is fine then you shouldnt have a problem, they cost like 5 dollars each, and that might be high
