Convert to GP Shift pattern :wavey:

[DZircher]

I would like to take the plunge and switch to GP (1 up / 5 down) shift patterns before next year.
My current ride, Duc 848 EVO Corse, has a factory mounted power shifter.



I'm not certain how to pull this off given the tight clearances in here. Does anyone know how to do this?

Thanks,
Dana

That a quick shift sensor on the shift rod? It's likely a directional switch. If so, switching is gonna mess it up.

Why do you want to switch? Just for a change? It doesn't really make things any better, faster or easier.

[Dannyf]

No can do with stock parts. You will loose DQS.

I feel like a lot of people think they should change for some reason....my race bike is staying regular shift for next year.

GP is awesome. you're all stupid for not switching

Check with gilles because they make the some great stuff.

i have vortex rear sets and have GP shift. i love it. hard exceleration is easier, and clutchless shifting is easier. dont know about switching your ducati, but i would imagine aftermarket rearsets would allow it.

[DZircher]

It looks like Woodcraft has a set that works either shift pattern.

I'll hook the component coming off the shift linkage to my scope/vom and see what it's doing in action. Could be a switch, it could also be a stress gauge (variable resistance). Either way, I'll update this thread with what I learn. If anyone already knows the electrical characteristics of this parts, let me know.

A normally opened micro momentary switch. This is interesting because it would appear that the switch doesn't close until considerable travel has occurred in the linkage. Given this simple trigger, I would imagine that a similar switch could be engineered for a different travel direction.

[Eric Baker]

Other companies make quick shift switches for either push or pull, Dynojet for example, so you can set up their quick shift on any bike no matter the linkage setup. If you want to switch it, you'll either have to get rearsets that allow it, or you may be able to change the sensor out and reposition some linkage to get GP shift.

Wrong. Gilles is garbage. Lets start with their support is awful. If you need a peg because of a crash youll be waiting. At the shop we had stuff (one peg) on back order for like 8 months. When it finally came in it took us a while to find the guy that wanted it. Second I dont know what they make their stuff out of but its about as hard as warm butter. You might as well just toss all the bolts that come with their stuff right in the trash and go out and buy some new ones. Youll be able to tighten them one time. If you want to adjust the position of the peg and you did use the hardware that came with the kit get some bolt extractors. I had a set. Also stay away from their chain adjusters/bike lift stuff. Same problem. Way too soft. Ive seen too many failures.

I find it much easier to upshift when leaned over with gp shift. Most useful exiting 3 and coming over the hill and then exiting the bowl.

or possibly a switch of a wire or 2

The bolts are junk I agree but I've crashed on both sides and watched an old r6 crash hard on them with just minor grinding on the pegs. However the op was looking for gp shift options and gilles has some amazing solutions for making bikes gp shift that other manufactures say is impossible. Is he racing this machine?

more than once, I offered to let friends that wanted to try out an SV, the opportunity ride my SV, when I informed them it was GP shift, they changed their mind

I switched only cause theres one increasing radius corner near my house that you couldn't shift easily coming out of the corner with conventional while still leaned over

Confused, how would conventional shift be easier? And I'm assuming you meant decreasing radius.

you read that wrong. he said its harder to shift while leaned over with conventional.
my room mate had GP on his SV while i still maintained regular shift. on one track there was a corner that would beneficial to be able to upshift but it was hard with REG shift but it was easy with GP. 2 corners prior to that though a downshift is needed so REG had the advantage over GP there

I'm trying to imagine a scenario where a downshift would be needed in a corner.
Enlighten me.

When you feel like crashing.

[SVRACER01]

there was a corner at firebird was similar to the 12 chicane but the other way. accelerate hard down the back "straight", start turning left (like the entry to 11), on the brakes hard, then flick right. you had to grab a downshift so you would have some GO at the apex of the right hander. gas it for a long opening left that required an upshift midway through.

especially leaned over enuf that ya wouldn't be able to get yer toe under the shifter

Somethin like turn 11.

youve been riding long enough randy to know that you dont have to be leaned over that far to drag a toe which is essentially what we are talking about here

You should be clicking the downshift when you're flipping.

You can grab a downshift while flicking into 11A. My slow ass and the way my bike is geared works pretty good.
