not winning with this quad, got absolutely no spark. Had no spark changed coil and cdi with ones off a working bike, it started then tried with first the original cdi, ran fine then put original coil back in and still ran fine. Did a few things other things then tried to start and back to no spark! its running a new ricky stator cdi and wiring and now new coil, loom only has one earth which is got a good connection everything else is so straight forward its crazy..... any ideas?

Start with a new plug gaped at .015, then check the air gap on the pickup coil to flywheel tab and set it at .010-.12
If that does not work then check the resistance on the stator windings and pickup coil
And remove the flywheel and shake it as hard as you can, if you hear any rattling then the magnets are cracked and broken this will lower the magnetic strength and hurt its ability to create power in the stator
