I'll betcha six pack of this fine nectar https://www.beeradvocate.com/beer/profile/12897/45919/ that you don't need a new coil or coils. Jest lift that tank, clean the connectors, crimp em' together nice and tight, pookie 'em up and you'll be back on the road again...
Found the problem, one wire had come off number 1 coil. Those engineers at the factory must have been smoking something wierd when they decided to put that coil where it is, just about need an endoscope to find it[wankers].
