My 1980 MX 175 G runs really good until it warms up after a while and it starts to lose its spark you can here it then it will lose it all the way then when it cools down it regains its spark and I can start it again what do you think it is I tried 2 different ignition coils that didn’t work do you think it’s the CDI box?
Probably The CDI Wires Melted when it gets hot then loses spark. if it cools down the contacts reattached and creates spark hope it worked
