John, next time we ride together you gotta show me this!
Well, you can in a synchro mesh car transmission, but depending on the vehicle the shift lever really has to be eased into a gear to avoid shearing the tips off the synchro rings.
Many standard 4 wheel vehicles are synchronized to ensure a positive, smooth gear selection without clunkiness by those not so aware of the engine speed and clutch handling. To save weight and complexity, more aggressive trannies stick with just dogs and cogs to engage each gear.
A standard gear has dogs and cogs that can be about 1/4" wide, and very durable. A synchro tranny will have the dogs and cogs but will add synchro rings that look like shark teeth in between each gear. Envisioning that arrangement you can see how sharp pointed teeth can be more easily damaged.
Howard, for your first try, choose to go clutchless between 2nd and 3rd. I would accelerate quickly to about 4000 then just lift the gear lever and ever so slightly, but quickly, back off the throttle and back on. Click, your in 3rd and accelerating hard.
Why you ask? To me the real benefit of clutchless shifting, is quickness. Don't really need to be quick around town so I don't. Also, if not perfect, which to me is harder at real low rpm's, the bike will lurch about. Others may feel not using the clutch saves slave cylinders, throwout bearings, clutch plates, etc. Probably to a point, but I wouldn't know.
I wouldn't worry about it too much.
