I have seen 2 RM STATORS that were bad out of the box. They are $40 because they are JUNK! They are made in China and are absolute pieces of crap.
Here is what I put on the banshee. It looks like the one he sells is a Ricks motorsports. Ricks motorsports is not the same as Ricky Stator/RM stator. From what I understand they make really good products.
