so thinking about put the big red gears i my rincon and maybe a big bore to a 680 (its the 650) just wondering if its worth the cost quad is payed for no payments like the way it rides just be nice to be able to run bigger tires with out any worrys doing so and don't really want payments for the next 4 or 5 years on a new ride. anyone done this what were the results? worth the money is cost?
