the drive shaft has a keeper c-clip holding it in..it's on the right end of the drive shaft...as your facing it..it sit's inside a metal ring looking thing..you will need a pair of retaining ring pliers to open it off the grove..pull it back towards the front on the drive shaft...once that is done,,take a punch..screw driver..what ever is handy.tap the drive shaft's end towards the front...this will seperate the drive shaft from the output shaft..once that is done..remove the drive shaft..this should alllow you to pull the cover off..this is unless there is another c-clip on the front of the drive shaft ?..if so.repeat the same on it...as far as your bike running..does it still fire one time..then stop ?..if this is the case..then your problem is the c.d.i..i've ran into this problem alot..and yes..you NEED TO HAVE THE SAME YEAR MODEL C.D.I..otherwise you wont get any fire to spark plug !!!..before you pull the side cover off..to get to the stator..i would highly recomend getting the right c.d.i for your year an make..it sure will save you alot of trouble.havent been able to get on lately but i still havent got this thing running. I'm pretty sure its the stator. I started to take the crank case cover off today but i cant get it all the way off because of the driveshaft to the frontend. How can i get the driveshaft off, i looked but cant find anyway it comes off. Also what can be used as a gasket for the crankcase cover once i get ready to put it back on?
