Thanks for all the replies. I have some options now for sure. I can replace the power pack, optic sensor and regulator myself if they need replacing. However, I am thinking the stator is going to be challenging if the fly wheel has to come off. Scott called me back and told me that he inspected his stator and found some flaws in it (thanks for calling me before I drove out there!) Anyway, looking to purchase a stator and have someone put it in for me.
