Lots of problems reported, mainly with the stator.
You need to get a voltage reading at the battery at about 4000rpm.
If your battery is bad you may never get a true reading but it is a good place to start.
If you do a search on this site you will find lots of posts on how to test your stator.
Fitting a volt meter to your bike is a good idea.
