So a friend of mine is telling me that I should replace the axle in my kart because it is the original one from 2007 when it was built. He says it will change the way the kart turns. Im curious if anyone has ever heard of this. Also was told that I should get new cassettes because the bearings slop around in them a little bit, mind you not much but prolly a 1/16-1/8 maybe.
