[ineed2fly]

I am trying to fix a pit-bike for a friend, it has no spark, I have tried everything I can thing of, any ideas?

is the switch off?
if it uses points clean that.
get another one off a working bike just to check to see if its the coil/cdi

Points - Clean and adjust

Magnetron - If it works, it works. If it doesn't, it doesn't.

Points....? I know what a magnatron is, but not points. I'll open the case today and see if I can't get it to work. Are points in the same place the magnetron would be?

Points (basing this offa Briggs engines) are behind the flywheel.

take off the side covers of the crankcase. down at the bottom where the crankshaft is

Test coil
test cdi
make sure plug is good
make sure kill switch isnt bad

 

[ineed2fly]

How do I test all these things?

First go get a new plug/try a known good one.

Coil: ground ground connection, ground spark plug to same ground, tap (dont hold it on there, just brush it real quick) pos wire on power source, spark should happen.

CDI, requires wiring diagram, multimeter and a 12VDC power source.

Kill, need wiring diagram and multimeter.

pics would help, probly bad points. check the spark, take out plug then put it in the boot. set it on the head and get some one to kik it over, if it sparks then your problem has got worse.
