So, my xr600 rebuild project has ground to a holt as im unable to get the thing to spark, im hoping someone can give me pointers as ive spent a few hours fault finding the ignition system and im now a little stumped. Heres what ive checked. New plug + Plug cap Checked all connections and wires for continuity, remade all connections with some contact cleaner. The bike has an electrosport stator fitted by previous owner, i believe its this one; http://www.electrosport.com/technical-resources/library/fitting-instructions/electrosport-esg410-fitting-instructions.pdf although the colored output wires are slightly different but Ive resorted to dissconnecting all connectors from stator other than ignition (BLACK/RED wire) that leaves white, yellow, orange, im unsure about what to do with the green (floating ground?) either way it wont spark with it connected to an earth or disconnected. The stator coil resistance is reading around 140 ohms which is quite low, stock stator should read around 250 ohms, i can get it to Read around 18v on the DVM if i kick it over by hand. Checked coil pack resistance, primary and secondary both within spec. Checked pulse generator resistance - 400 ohms again within spec. i can also see it pulsing on the meter if i kick it over. That leaves cdi, so off i went and bought a spare off ebay complete with spare coil. When it arrived yesterday i found it was slightly different from the standard as it was labeled mk2 instead of mn1, i believe this cdi is off an xl600 which should work just fine. Fitted them both and Still no spark, not even a whimper. So im thinking that either that low 140 ohms from the stator is the culprit or maybe its still the cdi and ive bought a duff one off fleabay??
