After your break in and first oil/filter change you may find it shifts a little different. I thought mine shift quite nice from day one. It was working so nicely that I would get lazy and miss a shift here and there. I'm planning on changing out the arm to a TLR which is shorter. This should make the action a little faster... stock it just seems like the throw is a little long. This arm also gives you the option to try GP shift as well. You can buy these for about $23 from online OEM suppliers.
Keep some pressure on the shift lever as you let the clutch out. It may snick in to gear as you are doing so. With the 650, my shift routine is the following...
Slight pressure on gear shift...throttle down while pulling clutch and applying firm pressure to shift lever......after I feel the click of the gear lever....I keep up pressure and let the clutch out....THEN let off of the gear shift.
This cured any of my infrequent missed shifts. I saw this technique on either an AMA or MotoGP race when they had a neat camera angle down at the guys left foot.
