Two stroke with no spark?

check the ignition system behind the fly wheel,are there points or a few coils of wire?if there are coils of wire check resistances on the pulse unit ,source coil,ht coil primary secondary windings on the coil ,if possible get a haynes manual for the bike,there sh*t hot

if it has a condenser then its a good possiblilty thats its faulty they do give alot of trouble ,the plug gap size is not a problem it will pretty much spark anywhere between .25 mm to 1mm but should be set at approx .5 mm.if its got a condenser then its going to have points too so they may well be causing a problem too check they are clean and they are set at aprrox .25 gap when they are open ok good luck mate
