JamesD84 Posted June 5, 2022 Share Posted June 5, 2022 Hi Everyone, Bought an old SR125 project that had been off the road. Long story short, it's just about having my life  with not starting. It's got good compression, got fuel, got spark (possible issue) and everything else seems good. I have bare bone wired it, to cut out out the sidestand, neutral and relays but no difference. Bike cranks but won't catch, it gets spark but seems strong first fire then not so strong. Battery is good and new so ruled that out. Pick up coils are good. Soooo I keep coming back to the CDI unit but I they are like hen's teeth. Could the CDI be bad but still giving a spark. Anyone used an aftermarket CDI unit?

Clive_D Posted January 16, 2023 Share Posted January 16, 2023 Hi, Assuming your carb fuel pipes are all good, have you checked the pilot jet screw in the carb is set correctly? Maybe lean or flooding. Link to comment Share on other sites More sharing options...
