--- Quote from: KXcam22 on March 31, 2009, 07:31:55 AM ---I started racing when I was 11 and haven't used the clutch since (for shifting).  My 78 husqavarna 390 used to wear the dogs but none of my newer bike have shown any ill effects. My K5 lasted 14 years doing this and still shifts great for the NO.  I do use it when climbing, braking and cornering. My wife and kids don't use it either (but then I guess I taught them). I actually think speed shifting may be harder on the trans but have no proof. I won a race once with the throttle stuck WFO and using the kill button to shift gears. Cam.

So you blimp your throtlle a bit or so than CAM???

I've ridden many track were is't no option to miss when shifting. You just simpley go immediately over the handelbars, so deep was that sand.
It was even hard (not) on my cr125 and 250 to shift WFO on those tracks, without clutch or letting of the gas.
Although letting of ment you risk to see you front fender real close. :)

But maybe it was just me :|

Dutchie,
  Yes I let off the throttle momentarily (to unload the transmission) then apply the throttle and shift at the same time. Happens to fast it looks like I am blipping the throttle. Cam.

Polar-Bus:
When I raced 125's years ago, clutchless shifting was almost mandatory to maintain momentum. Once you learn the exact technique, you pose no harm of accelerated wear on the shift dogs.
I race 125cc shifter karts with a CR125 powerplant, and with karts, you only use the hand clutch to stop and start. Like others commented you simply make one perfectly synchronized motion:  unload the gearbox by abruptly letting off throttle, abruptly shift into the next gear, back hard on the gas. Once you have the technique dialed in, you will see almost no rpm loss, and the actuall shift will feel very smooth. If the shift feels notchy, or you feel resistance, your not unloading the gearbox correctly (I am also shifting my kart consistantly at 12,300 rpm's), and kart racers go  years without a tranny rebuild

If you have afford by Starlane powershift VX and a battery (12v 1,3a) in airbox and problem solved! :wink:
