Has anyone ever have shifting issues? Like you are downshifting then everything goes too smooth and no shifting of gears at all....I have been stuck at stoplights pushing and yanking on sifter and nothing..then suddenly everything is fine. I have removed the cover and saw nothing wrong to the eye. Fluid good, no metal shavings, nothing I can see. What gives? Makes me kinda dislike riding such a badass bike. Oh, it's an '07 xb12r if that matters. What fluid should I use? Everyone has a different idea so what do I choose? This transmission thing irks me, its got only 7500 miles..is that a lot? I don't know...
