I have an '03 ZX6R and I've got some problems up-shifting. It seems that it takes a hell of a lot of upward travel before shifting into the next gear. Sometimes, I'll pull in the clutch and upshift and I won't hear or feel a thing and it turns out I'm not in the next higher gear. So, this causes the engine to over-rev and I have to shift AGAIN!!! Anybody else have this problem? Is there anyway to adjust the pedal? Will switching to synthetic help? If the oil helps smooth out the shifting it won't happen for a while because I only have 943 miles on my bike and I'm waiting for it to get to 1500 before I switch to synthetic.
