I am looking to reverse the shift pattern on my GS500.  Can anyone guide me to a company that makes rear sets or a kit to change the shift pattern to "race"?

Thanks,

I have CFM Woodcraft rearsets and have set them up for GP shift. The pedal is the same for the GSXR, TL & SV. I bought a 3-piece Woodcraft pedal but you can use a factory Suzuki as well. I have several of them that I have as crash spares. I used a knuckle form one of those bikes as well. Then measured for the length of rod that I would need. I do not recall which bike it was from since I dug through a box to find the right length. I can measure the length if you need it. The left peg that comes with the Woodcraft rearset will not work. I bought a replacement peg for the GSXR, TL & SV rearsets. These pegs have 2 tabs that stick out that fit into the rearsets. I notched the left rearset plate the accept these tabs. They keep the peg from rotating.

Greg Gabis makes rearset plates similar to Woodcrafts, which uses their pegs. I have not seen any pics or prices of them.

Stock CBR600 F3 rearsets can be made to work.  Requires a bit of modification, but it's fairly cheap.



Just flip the linkage and you get GP pattern.

I have a set of those cbr rearsets, complete, for sale ...$50. I bought them intending to install them but sold the bike.

Note that the major work necessary to get it to work is having the shift linkage rod (at the shift rod) welded to the attachment of the stock shifter...you can see the weld in the picture above-right at the shift rod location-easier to understand that way.

Also check the link to my site as I have some info and photos there.

Why do you have to weld the shift knuckle? Does Honda use a different thread pitch/diameter than Suzuki?

BTW...I am really suprised by the angle of the 2 shift rod connections in the pic  that you do not have problems shifting. They really need to be parallel with each other to avoid binding or other problems. In a GP shift they could easily be aligned.

Yep, exactly.  The splines don't match up.

I know what you mean - I was concerned that there wouldn't be the proper leverage or that it might bind, particularly on the downshift where the angles are more extreme.  I had the knuckle welded in a position as far vertical as I could w/ out hitting the side of the case when upshifting (I have about 1/8" clearance).

It seems to work fine... No problems shifting.  I suppose it's probably not as crisp as if they were parallel.  :dunno: But after switching from stock I didn't notice any increased difficulty, although it took a few miles to get used to.  Maybe I'll flip the linkage to GP pattern just to see if it improves it.

Probably the trickiest part was making the rear brake work.  Not sure if the CBR master cyclinder would work, but mine didn't come w/ it, so I used the stock GS one.  I had to cut the pushrod to mate it up t the CBR brake pedal.  I didn't reattach the brake light switch, although rigging something wouldn't be too hard.

I have pics of the install if someone was interested in this little project.  Not really difficult, but requires some fiddling/grinding/and one weld.

Thanks guys,
With the F3 rear sets, what happens with the right side?  Does the right work, or do I need further parts to make the brake operational?  

I am looking to the possibility of modifying the stock brackets to accept a GSXR foot peg and linkage.  That may be the cheapest route.

I guess I need to call CFM on these, I don't see them listed on the web site.

Hey vroom...I noticed in your sig line that you are using an  A.P.E. cam chain tensioner. Is it for a GS or SV? I have never been able to confirm that an SV will fit.

Again, there was some modification required to make the GS cylinder work w/ the CBR rearset.  If the CBR cylinder will bolt up to the GS brake lines, then this may not be necessary.  But, I didn't have the CBR cylinder, so I had to modify both the CBR rearset and GS cylinder.   Only additional parts were a few washers.

Here's a pic... I'll try to explain:



The cylinder mounting holes on the rearset need to be slotted slightly to match the cylinder's.  Easy.  Also, I added some washers for some clearance.  Also, easy.

Slightly more complicated, is that the clevis on the cylinder pushrod, doesn't match up to the hole on the CBR brake pedal.  The position of the clevis can be adjusted by screwing it in further on the pushrod, but it has to be up so far, the pushrod sticks out of the bottom and gets in the way of the pin. But, I simply cut an inch or so off the pushrod and it works just fine.  Easy!

The brake light switch is simply a pull switch that is operated when the pedal is pressed.  The stock switch will not work on the CBR rearset, because its mounting hole needed to be cut to clear the frame.  A simple bracket could probably be made fairly easily to facilitate the switch.  I haven't bothered, since I never brake w/ rear only.

Was gonna do I write up for Mr. P... but never got around to it.

When I got mine from APE they didn't know which one would fit either.  So, I sent mine into them and they matched it up (I totally forgot about this).  I believe the one that it matched to was for the 97-00 GSXR600's.  I am not positive on this though.  Which may turn out to be the same one for all of the new GSXR's.
