Man, am I glad I came across this post! I have been chasing a hard starting, some times no starting banshee for a year! My bike is newly rebulilt and still giving me a pain in the ass with random spark. I pulled off the flywheel the other day and was ready to drop $300 on new oem stator untill I saw this thread. The engine is new by fast and yes the carbs are dialed in. My setup is in my sig for info. I have the loose sand sound in the flywheel. My question is, is the flywheel most llikely the problem or should I replace the stator while I am at it? Last time I ran the bike it ran for a day and then would not start the next day, not even pull start. I have done several visual spark tests and sometimes it sparks, sometimes it doesn't. I even had one side sparking and not the other. I am sold on the new oem stator if that is the problem because I don't believe in buying used electronics. Where can I get a quality flywheel? The new oem ones are a rip off! Thanks guys! p.s. the coil is new.
