I used to miss gear's on my ZX6R , but i now use Race pattern ,ie down for up & up for down Never missed a gear yet ,would never go back to road pattern !
On the track a reverse shift pattern is the way to go, in conjunction with a quickshift -.- luvvverly positive changes every time and take 5 yards out of everybody else without a quickshift, just hold the throttle on the stop, especially on tracks like Snetterton with long straights.
DJ, Last time I opened the left case up on the 916 we found out that the selecting fork had a little bit broken. This little bit stops the gear selection to overrotate which is likely to select false neutrals. If this happened on mine it probably happens on some others too and this is may be something you ought to check. Cheers p
