Hi everyone I just acquired a 1980 XS650 (ran great and just died on the guy) for a measly $100 payment. It has no spark and I am unfamiliar with this bike and have been out of cruisers for a while (I've built a few Vstars 650 and 1100) but had moved to street bikes (Triumph Daytonas and the like). This bike has the CDI unit, dual coil. I have no spark and major lighting issues. I could care less about the lighting issues as I'm stripping it down and doing a hard tail bobber. But is there a diagram with meter tests I can run on the CDI, Coil and Regulator and check what my bad component is or where my problem may lie? And is there any homebrew repairs for the CDI unit if thats bad as the price of those I've seen at some outrageous prices. Thanks ahead of time.
