I know many have talked about changing the front sprocket on their bikes. I did this on my z400 a long time ago and the thing pulls awesome!. I bought the 450 a couple of weeks ago and bought a 13 front sprocket, I did not even ride it stock, I just put it right on. While riding with some guys in the dunes, it seemed like I was always between 1st and 2nd. 1st was winding out, or 2nd was lugging. I am going to get a 39 for the rear, what do you guys think? Should I go back to stock so I actually am cruising in 1st more, or gear it down some more to utilize second more?
