Re: clutch less shifting

[dan & ann curcio <curcio@xxxxxxxxxx>]

You are correct.  Upshifting without the clutch can significantly damage
and/or increase the wear rate of the transmission gear engagement dogs
(similar to synchronizers in a manual shift car) and if done poorly can bend
or break the shifting forks.  While there may be no noticeable difference in
shifting effort when not using the clutch there is a much greater load placed
on the engagement dogs as you are forcing them to synchronize the shaft speeds
inside the gear box while they are still connected to two different driving
forces (engine and rear wheel) spinning at different speeds.  When the clutch
is disengaged on an upshift the load is reduced as the engine drive is just
freewheeling.  You can get by with clutch less shifting for awhile, but
eventually something is going to give out and symptoms like those mentioned
(popping out of gear or missing gears) will show up.  At that point all you
can do is rebuild the gear box.
Moral of the story:  Use the clutch,  that's why they put one on your bike!
