try a new plug, measure teh coils resistance

Try a new plug.............still nothing check the plug lead and if nothing go backwards from there.............

[FA50 rider]

will do how much are new plugs and what type will i need?

[cheese]

The bike shop will able to sell you one from the model and year of the bike.

Important!

Prak the bike in your gargre before checking for sprak.

[Ivan]

check the plug,

Also check that your earths are good and not rusting, or broken,

Check all wires are connected


check for spark again


then yeah check resisence of coil etc

[FA50 rider]

i have check all cables and earthings and still nothing, ne more ideas?

[bungbung]

Have you checked for voltage on the low tension side of the coil?

If nothing, work backwards - points not opening? (if not CDI)

Depending on the year, it'll have points or a Cdi ignition. Look at the cam cover for CDI lettering to work out which is which.

Points fine? check the resistance of the ignition windings for open circuit
