I've recently been having spark problems on my 2004 typhoon xr50 I've changed the cdi and ht lead the lead is a ngk racing lead it has a new ngk plug a new stator new battery the only things that havnt been changed are the relay and regulator/rectorfier could these be causing a problem and how easy is it to blow a plug on a 2 stroke ?
Oh yea and I've had the whole loom out and replaced all earths and any damaged wires and plugs and cleaned all terminals I'm stumped can't think of anything else to do :-(
