wild foamy Posted June 22, 2009 Share Posted June 22, 2009 if I kick it over normally I have no spark, If kicked hard I have spark Weak magneto? my dad was telling me about how his dad used to have an old BSA with a sidecar with a weak magneto, he used to take the spark plug out and warm it up on the stove or using a blowlamp to get it going, the bloke he sold the bike to put a new mag in it and it went well after that its worth considering, not sure if you can test them or not Link to comment Share on other sites More sharing options...
Moderator Airhead Posted June 22, 2009 Moderator Share Posted June 22, 2009 Get yourself a manual and test the stator coil against spec and also ignition HT coil... Link to comment Share on other sites More sharing options...
