Just saw your mt motor for sale, now thats a crazy price for a 3" motor.ok this is good from a knowledge base stand point,but i dont see the point really??most of us on here know the differences.though,i have never used any of them (because everyone for some reason wants millions of dollars for them) so never could afford them.and im not bashing you at all,i mean you took the time to compare and contrast which is a good thing but again im confused as to why??
