I have two different motors that i am looking at and not sure would be best in the long run for me. Tha first is a really nice single carb 61x for a great price.The other is a low hour 760,both are complete and stock.Should i buy the cheaper 61 and spend the extra money to hop it up orspend more for the 760 and drop it in and go?I am freeriding on flat water only
