OK, one of my girl's said that she will not wanna ride the mini with a modded out 6.5 on it. So i have to get a 2.5 for when she wants to ride. Is the bolt mounting the same? Do they use the same carb, i will not be doing the jetting and all that stuff. Unless you guy's have done some mods to a 2.5 and it has helped. Other then maybe a pipe,that is all the time i would put into it. The shaft will take the smaller clutch, that is all i got a chance to see when i was at HF the other day. Just wanna have a 2.5 on hand that i can swap if she want's to ride, 6.5 is for daddy on the weekends. Anyone got any little mods that would help it out.:thumbsup: Any help would be great. Thanks John..
