    Who do it? I tried it tonight and I found it very efficient!

    I think most engines transmission can function temporarily without a clutch, though it is vital for moving off! Once on a roll/ moving, the best situation is when the engine RPM is just right to drop into gear. However, the clutch gives the engine and transmission a temporary break from one another, (a breather), and its definitely there to allow smoother, safer, gear changes and cool the friction plates momentarily too! On a motorcycle not having the greater stability of 4 wheels, it allows a smoother transition of movement. Finally, clutch plates are relatively inexpensive against transmission rebuilds, if something goes horribly wrong!

    :hello: Once in awhile I find myself shifting without the clutch. Why I don't know but the big ZLs do do it well. :notworthy:. You ever do any power shifting. It's when you hold the throttle wide open & don't let up on the throttle while banging through the gears. It excites me. :laughing7:.

    Yessss roll the throttle and just before shift point, put a bit of pressure with your feet under the peg. Shut the throttle and the gear will engage without a bit of noise or resistance. Then roll it again. This can be done real fast.

    If my gauge is the absence of « clunk », clutchless shifting is the way to go.

    I presume you are talking about changing up with no clutch. Changing down using the clutch, always taught to pull in the clutch lever, blip the twist grip to rev the engine so as to get the engine spinning faster to match the transmissions increased gear speeds with a down-change! Probably this no-clutch use is the perogative of a bigger torquier engine, running at slower engine speeds, but having more mass in its internal components. I wouldn't like to try it on the Buzz-box 400/4!
    I suppose its almost like a synchronicity, just perfect at one particular point in engine transmission function!

    My gut feeling is those times when the shift is attempted and the timing is off you put a great deal of stress on your tranny. I used to have an old Chevy pickup that you could shift smooth as glass if you timed it right, but I've not been able to achieve that with any of my bikes. IMO when it works, you are lucky. When it doesn't you are beating the snots out of your trans for no reason. A basic rule of thumb here is that if it worked, why doesn't everyone do it?

    Sounds like the main advantage is for racing. All I'll add is it is all good fun until you break something. Then as you push it down the road you can reflect on why you didn't just pull in the damned clutch.....LOL

    Hey, it's your bike, do what you want, but I think the clutch is a cushion against less than perfect shifts. It keeps your gears from engaging violently, which I suspect is going to happen once in awhile. I like my bike and don't want to break it. Especially over something silly like this. Once more I'll state the obvious. If this was a good idea, how come everybody doesn't do it?

    I feel the same way. :notworthy:. In the back of my mind I vision tranny parts flying everywhere. :laughing7:.

    In the days when I was drag racing my ZL1000 I used an air powered shift mechanism. Hooked it up to the horn button, a press of the button would temporarily cut the ignition for a split second, fire off the air cylinder that was linked to the shift arm and it worked great, no need to back off the throttle or pull the clutch. Made hundreds of passes on the drag strip with that. Something like http://www.mpsracing.com/products/MPS/as01.asp
