    What's everyone take on this using it to shit up?

    I don't after I get out of first, just find that she flips into gear just fine without using it...just roll off the throtle a little bit, knock it up and hold on.

    I use to to down shift, BTW.

    I don't use my clutch at all while upshifting, not even when im going from first to 2nd.
    Its optional

    man.... now that you mention it... i dont think i ever used my clutch to downshift....

    on my f3 cbr i used the clutch mostly to get out of first because rolling off the throttle for that split second in the higher rpms really threw the bike on its face for some reason... after that just bang gears like you stole it :bigthumb:

    my boss was clutchless shifting and gunning his harley. he said at about 70-75 a car weaved in at him, he gassed it and down shifted. bike made a clunk and he pulled over. trucked it back to his house and ripped the tranny open and he sheared gears off the shafts. he brought it into work one day to show me. pretty impressive

    clutchless shifting from 1-2 will probably kill your tranny

    1994 900RR 24K miles runs fine
    02 Busa 3500 miles no problems
    04 R1 17K road coruse/ wheelie miles runs smooth
    All the other bikes I have owned never had any trans problem.


    BTW 04 R1 even has the orignal clutch

    nope.

    when done properly, the transition is harmless and akin to shifting with the clutch.

    the clutch unloads torque from the mainshaft to allow the gears to engage/disengage the dogs by the movement of the shifter forks.

    when you back off the throttle slightly, it does the same exact thing... unloading torque from the mainshaft for a split second.

    but realize torque is then reapplied to the mainshaft if you dont shift fast enough as when you begin to coast, opposite torque is reapplied to the mainshaft from the rear wheel being forced to continue driving the transmission while in gear.

    but clutchless shifting in based on using that split second of mainshaft unloading to shft harmlessly.



    but downshifting without the clutch results in sudden chainlashing and wheel chatter as the rear wheel is forced to quickly speed up to make up the differential in engine and mainshaft speeds, which is not apparent during upshifting. the wheel chatter can cause a loss of control, obviously, in addition to stretching the chain, wearing the sprockets, increased cush drive and bearing wear, clutch wear, and increased tyre wear. this is less substantial on a back-torque limiting clutch system, though.

    I usually don't use my clutch unless I'm doing something retarded.
