Whenever I shift from 1>2, 2>3, or 3>4 on my 2011 cbr125 I get a nice click sound along with a smooth upshift. However, when I'm shifting from 4>5 and press up on the shift lever it feels like the shifter only goes up half way and I do not get that nice click. However, once I let go of the clutch I then hear the 'click' and the bike engages into 5th gear. Anyone know what's wrong?
