Brought this bike a few weeks ago was running like a bag of crap.thinking it was the fuel drained and replaced with fresh but won't start at all. Having the carbs striped and cleaned soon it has new plugs but when turning the bike over I'm not getting any spark from any of the plugs checked all wireing i wouldn't think that both coils would pack up at the same time so I suspect it could be the cdi unit thats at fault any ideas would be great.
