Please help, while at the track last week my bike started kicking 2nd gear back into neutral. As soon as I shift into 2nd and hit WOT it gets kicked back. Only happened twice but it has me worried about a more serious problem. Has this happened to anyone else? Bike is an 03 AE, Yosh RS3 4 into 1, PCIIIUSB, Air box mod, TRE, 16/42, lowered 1 in front 2 in rear, and only has 3700 miles on it. Could this be caused by a chain that is too tight or just a bent shift fork? Thanks all.
