Faster shifting hyper!!

[08hyper]

Well today I installed my Dynojet "quick shifter" OMG!! what a great MOD!!

I had never tried a quick shifter before until my buddy Timmy (that ktm guy) let me try his bike, and it was awesome! I HAD to get one!

I have a Power Commander V that I bought a while back getting ready for when I get the mid-sized tank & velocity stacks, and then having the Hyper dialed in on the dyno. I just found out that I could install the PCV with a "zero" map, so it will not effect my DP cams ECU that I'm using for now.

You will need a PCV to install a quick shifter, part # 4-113, installing the quick shifter IS a BIG PAIN IN THE A$$, as the shift linkage on my DP rearset is short (like the stock one) and the quick shifter goes in as part of the linkage, I had to shorten the heim joints, by cutting, grinding, retapping, and then grind both sides of the body of the quick shifter to make it fit. It barely fit, but did.

I can now upshift the bike pinned full throttle with NO CLUTCH, which makes the bike accelerate crazy FAST & SMOOTH!! its SO COOL!

With my MODII (Motor of Death II) I can only use the quick shifter in 4th, 5th, & 6th, in the first 3 gears I can't keep the front end down, if I nail it in 2nd, and wait for the front end to start to come down, hit 3rd and the front end will come back up again without ever hitting the ground! (without trying)
So while the install was a big PIA, for me it was worth it!

I can't wait to try her out on the track! its gonna be FUN! Aloha Alex

Sounds like a nice mod. Have you tried shifting getting into and out of corners? Will it make the downshifting too abrupt with the compression braking?

Out!

It doesn't work that way Axe.

It's designed for upshifts only as you have to chose between the "pull" or "push" actuator switch.

Just like life, you can't have it both ways.....



Besides.....I don't believe one word that Alex says about it....

I guess I'll just have to ride his bike again next time I'm out there to find out for myself.....

not sure what your saying.....

the "quick shifter" does NOT affect downshifting, you use the clutch like normal when downshifting, the bike will run just like stock when you use the clutch, in fact you will never know you have one, until you pin the throttle WFO and just bang away upshifting without the clutch. Aloha Alex

Cool, I was wondering when one of you maniacs was going to get one. I was looking at the Power Commander website because I think I need one. After installing my full termi system my bike runs better but is a pig on gas. Gas light comes on after 60 miles. I thought it was only available with the PC3 good to know you can hook it up with the PC5 also. Going to add that one to my long ass wish list.

I often upshift without the clutch as I find it smoother at speed... is this bad?

I AM GETTING ONE FOR babyxerox right now!

No not usually, but can be bad if not done correctly, if you do not "unload" the transmission by chopping the throttle long enough before shifting, you can put a lot of stress on the shifting forks, and they can bend, and there goes your tranny.

A better way is to "speed shift" is by fanning the clutch when doing the WFO thing. Aloha Alex

You can effectively unload the gears with only a 25% throttle reduction, and
it can be done very quickly. The paddle shifter on my Birel DD2 kart only cuts
the ignition for only 50 msec during a shift, which is 0.05 second (half a tenth!).
Due to the design of about 98% of modern motorcycle trannies, you will get
more gear grinding and wear with a slow, deliberate up-shift than with a quick
bang of the lever. It is important to go full travel on the lever, though. Up-shifting
with a shorter than full throw is generally a cause of false nuetrals. And with
stiff riding boots, this is easy to do!

There is a riding tips version of Sport Rider out on the newstands right now that
details the techniques of speed shifting a motorcycle without any added hardware.
A lot of guys have been doing this for years without any damage.
Yeah, yeah, a lot of guys aren't on finicky Italian machinery, either...

I'm not sure I agree with your statement that a quick bang on the shift lever (upshifting) with a throttle reduction is easier on a transmission than a slow deliberate upshift using the clutch. If that were the case, I think the motorcycle mfgs would say to shift that way.

IMHO with many years of Motocross racing & just plain riding this is what I've found out, when shifting a motorcycle.

(For street bikes)

1. the best way to shift a bike is to chop the throttle & use the clutch, just like the factory wants us to do.

2. "speed shifting" holding the throttle wide open, and fanning the clutch to upshift gears, this method is easy on the transmission but hard on the clutch

3. "bang shifting" upshifting without the clutch while quickly chopping the throttle to unload the transmission, this method is easy on the clutch but harder on the transmission.

Both 2 & 3 are good methods, but must be timed perfectly to make work, and if you do screw up you will miss gears or grind them, something the tranny will not like.

Now this "quick shifter" seems like a better way to go, the best of both worlds, fast shifting that is easy on the clutch & trans. It will time everything for you, for perfectly smooth shifts. Really cool!

There is no way I could make my Hyper accelerate faster whether using the speed shift, or bang shift method, against the "quick shifter"

As always, your mileage may vary, Aloha Alex

So there is no way to fit this unless you have a PCV, is there any sort of add on to adapt it to a PCIII?

Got any pics of the install?
