Hey All, I've got a GSXR 600 K6 which is stock, apart from an after market exhaust. The issue I'm having is that I appear to be hitting the rev limiter before I hit 18K on the tacho. Actually my maximum seems to be around the 14K mark. When I get to this mark, the motor starts to violently back-off... My question is what speeds should a stock bike hit in say second gear? If the same bike (GSXR 600 K6) can hit say 160kmph @ 18K and my bike hits 160kmph @ 14K then I know the tacho is a bit stuffed, but the bike is fine. Any help from other GSXR 600 owners? Thanks.
