On your posted need for the wiring diagram of a Honda CR250, would this help?

Good luck and thank you for asking FixYa.

SOURCE: no spark put on a new cdi box coil good and a new

hi,sounds to me like your cdi pickup unit has failed,i am not 100% certain but this will be located on the end of the crankshaft behind one of the enginecovers,there could be two other possibilities,motox bikes are notorious for breaking wires so check the wiring from the cdi sender unit to the cdi box and the coil,also check your "off"button it may be stuck in the "kill" position..hope this helps..cheers ian

SOURCE: 2007 KXF 250 electrical problem

when the ignition parts like the coil and the transistors in the cdi unit gets warmed up they dont work as well as when there cool,,,so a problem thats not there when cold will be there when its hot,,,,if the stator has a small fault in it when cold when it gets hot it turns into a big fault! the best way to find this fault is by swoping one part at a time till you fine the faulty part,,,or put it into the bike shop and pay through the knows for the fix? have you a friend with the same type of bike you could swop the parts with??? it a big big help if you have! i would start with the coil then the cdi unit,,,there the most likley parts to play up when they get to hot they go faulty!

SOURCE: weak spark--put on a new

May be CDI, but check all your grounds first. Make sure you have a clean metal to metal connection of the coil to frame. Disconnect the leads going to the kill switch also. you may have a high resistance to ground short. Also, did you replace the lead coming out of the coil going into the spark plug? did you reuse the old lead?

SOURCE: i have no spark on

if you have replaced all that it sounds like it is the stator. its an alternator for small engines. get one on ebay cause factory are always expensive. its located behind the pull start. take that off then the side case cover.
