kashim Posted September 20, 2012 Share Posted September 20, 2012 Does the engine turn over? What kind of spark plug was in the bike, Iridium or Platinum ones can give a good spark to a lean fuel mix. Link to comment Share on other sites More sharing options...
kashim Posted September 23, 2012 Share Posted September 23, 2012 For the sake of a few quid, you might as well get a replacement coil and it's not at fault you can always sell it on after. > http://www.ebay.co.uk/itm/Yamaha-YBR-125-Ignition-Coil-and-HT-lead-for-2006-CARB-models-/290778933054?pt=UK_Motorcycle_Parts&hash=item43b3c6673e And some other wiring bits > http://www.ebay.co.uk/itm/290778939084?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 Call out charges and workshop fees are a bit of a rip, but you'll spend days trailing through Haynes manuals, wiring and various wiring diagrams going nowhere otherwise.
