Help!!!! CR 125 99' Not sparking well

[Themotocrosslad]

Hi everyone, i have a honda cr 125 1999 and its never been right for more than 4 months, Recently i have just have to tackle the problem of no spark with my bike, i was riding and it just stopped sparking, I fitted a brand new stator, Still nothing, so i got a mechanic to look at it and he has replaced the spark plug and cdi unit, he said the cdi was shot, it was off a honda cr 125 1997-1998, now i have a spark but its weak as hell, i can hold the damn plug with nothing but a slight tickle.. and it inly sparks once with a big kick, I disconnected the stop switch and checked all the wires and still a slight spark, i rung the guy and he said he will drop of a ignition coil tomorrow to see if that was the problem,

I thing it could be the coil but also i was wondering could it be the flywheel because there is a slight gap that looks way to far apart between the magnet on the flyweheel and the stator, I dont now what else it could be, i need this bike fixed so i can sell it its been nothing but trouble,

Key notes, New CDI, New spark Plug, New Stator, Full engine rebuild wth seals done as well just before it stopped sparking, Need help so much, i am only 17 and i have quite a vast knowlage or mechanics but not electrics :/ Help would be much appreciated, I have owned the bike for 2 years and never been able to have a good long ride on it for problems arising.. :whoa:

Clean all connectors with some electrical cleaning spray.
Then check the resistance of the coil. The manual should have those numbers.
If that checks out measure the stator, even if new.

I'd also try a compression test. Many of those previous owners statements of having new pistons put in are most likely "selling arguments"

Hondas have the best high voltage coils but the worst magnetos.
Time and abuse (dropping them) weakens their magnetic force.
