Jet settings for 2005 cr250 - 2005 Honda CR 250 R

blocked main jet in the carby
have it professionally overhauled

this should get you close, will still have to fine tune due to exacting conditions.....humidity, temperature, pipe, silencer and reeds....however try this:

Main 360
Pilot 20
Needle H1-70
Needle Top Clip
Air Screw 2 Out

most likely main jets clogged.

the cdi is the best bet but get a test light and have someone kick the bike over while you see if the stater has power comming out of it the stater is on the left crank case cover you will see the wires comming out of the cover but the cdis go out a lot more often than the stater with the bike being a 05 its a 90% shot
