Question about 2003 Yamaha YZ 250
It was working just fine and then it set for 2 days when i whent to start it agin there was no spark i got a new spark plug and that didnt work so does anyone know what the most common thing to go out the electrical system coil, cdi or magnito or if there is something else for me to try please let me know
Electrics have had two days to plot...lookout!
I've just spent an entire summer re-beauting an IT250J. From all the dealers, parts seller's and on-line info I've gathered, ignition coil is usually first "component" to go. (assuming all wires/ connections 100%) Black boxes (cdi) and stator coils are fairly robust. I can tell you testing them is very expensive and WILL lead to more $$$ if you are any way ignorant of Ohms and resistance parameters. For $40 odd, try a new coil first.
Bear in mind, loose connections will have an effect on all electrical components in the system if not fixed quick enough.
