I'm the guy with stator leak... Well toke that sprocket off.... Looked for bad seal... All was good.... Decided to clean the area really good... Noticed grooves in the case....and low and behold there was a pinhole in te case.... Put some oil in it... Started it and it came right out when running.... So my Theroy is the chain rubbed on the case.... Because tue chain roller wasn't on.... I now put the chain roller on....and planning on jb welding the case.... Will this work? I hope so....
