So i was riding along today, practicing wheelies and what-not...on my way home, i wasn't thinking and shifted...without clutching. I found that we can power shift on our bikes after about 5000rpms...I checked it in all gears and sure enough...all gears after 5000 we can power shift...actually I wait until 6000 but for all you racers out there...clutching is now optional without DynoJet's QuickShifter

You can actually do clutch-less shifting at anytime (although it's not very easy going from 1st to 2nd because of the nested N).
All you have to do is accelerate and put some preload on the shifter. In other words, put some pressure on the shifter. When you are ready to shift, roll off the throttle some and continue to apply pressure to the shifter. It should slide right into the next gear pretty easily. Then just roll back on the throttle and away you go.
It takes a little practice, but once you get the hang of it, the shifts get really smooth. :thumbup:

"roll off" = quick flick of wrist
with full throttle, put pressure up on shifter, then flick off(just a bit) the throttle, it'll pop into the next gear. You can do it pretty fast, although it's not recommended by Yamaha. I'll do this sometimes, but I'll usually also tap the clutch at the same time.

I have done it pretty much all speeds and RPM ranges without a problem, it works good!
There is always friction when shifting and re-engaging with the clutch plate. The rolling off is done quickly to help reduce wear. Racers get their clutches for free. A question of $$$$.
Sure you can speed shift, but at what cost? Checked the owner's manual and it states "Always use the clutch while changing gears to avoid damaging the engine, transmission, and drive train, which are not designed to withstand the shock of forced shifting." Remember, this is not a track bike.
Personally, I feel that if done smoothly and only occasionally, no problem.

I understand that...what I'm saying though...is for those people who were talking about racing...this is a way for them to accelerate from start to finish without slowing at all...not recommending...not really saying anything other than we CAN accelerate continuously without EXTRA stuff...DynoJet's QuickShift just stops the flow of gas for a split second...has little to do with the clutch itself...and if your RPMS are high enough...neither the clutch, engine, or transmission is affected...yes, prolonged power shifting can cause damage, but grinding a gear does more damage than a power shift will (if done correctly)
In a car...power shifting is never a good idea...but when you have a car that can break 200mph and don't have a quick shift kit or paddle shifters...power shifting can be a way to shave off a few seconds, which is can make a world of difference...
On a bike...if you decide to race a bike that has high top speed, but slow acceleration, a few seconds might come in handy...especially since our bikes are geared for low - mid-range performance

I'll use the clutch and get you in the turns!

i also get this.... almost feels like the clutch is slipping right? It pisses me off, but my bike only has 2K miles and clutches are not covered under warrenty
i dont know what this could be...

humm, so since others have this problem... does this mean our bike has a weak clutch or something? i only have 2500miles, but i swear it slips sometimes under full pressure (which IMO, i should NOT!)
