Why can't I shift this thing right

One thing mentioned in another thread is the PCIIIUSB Quick Shift option. That uses a load cell on the shift lever to send a signal to the PCIII controller when the shift is desired. The controller then kills the injector pulse width for a few milliseconds to unload the engine so the trans can pop out of gear and pop into the next gear. IF the timing is perfect the dead injectors cause the engine RPM to drop....just enough during the programmed time interval to match what it needs to be for the trans to engage into the next gear. This is very easy on the trans as the time interval (roughly 60 milliseconds) the engine is dead is very very repeatable and calibratible so that the gap in power is perfect for that bike and that trans. The other reason it is easy on the trans is that the engine is slowing itself down because it is not firing....it isn't forced to suddenly drop in RPM due to the sudden gear engagement. I suspect Yamaha is using a variation on this to control the AE transmission along with a solenoid to move the shift lever for you. Just my speculation.

This is right on. All of the interruptors I have seen are adjustable for this very reason-as well as an adjustment for length of interruption.

See what happens when you ask a bunch of gearheads how to shift? You get more advice than you could possibly imagine. Bet you'll never do that again!!

My '05 was kinda notchy at first, but seems to have settled down nicely now. Credit this to nothing more than break in and a clutch that was a little sticky when new, but that went away too. Accourse I never had a cruiser, so I never developed the slow-shift habit.....

Yea, stomp that sucker when you shift. Preload? Hah! If I could have figured it out, I might have used that sissy preload, but after the first thousand miles of serious up and down the the gears, it shifts like butter.

After 32K miles, I still give it positive and quick pressure to shift, even stomp on it every once in a while, cause she likes it, but its not really necessary. Its now officially broken in and butter smooth in every respect. This includes the neutral to first shift, somewhat like a rifle bolt action clunk there most times, which is completely normal for this transmission.

When I added the PCIII to the bike the RPM's changed, raised to about 1075-1100. The shifting was smoother with the idol speed higher then the 1050 stock setting. With it set about 1075 the revs are smoother, with less vibration, when I blip the throttle.

I also noticed that setting up a turn in the twisties was a bit faster with less "fall off" of speed and smoother compression braking. It let me use a lower gear and keep the RPM's higher for post apex accereration. :good: :good:
