This is going to sound stupid but if I have a stock 121in track. And i clutch and upgrade my motor on a 03 800 xcsp would it go faster on the big end? In theory its would make sense to put a 136 or a 144 on it but I'm just wondering. My buddy and I dont agree. My thought is that on take off it would have more grip less slip. And on the big end it should go faster due to a longer track. Like a bigger tire. Would it be better to get a team secondary too? That's just my thought. Any opinions would be great.
