I don know what the inside ID is of the TB is for the 600

It's 40mm. also.
FWIW, the intake manifolds I'm measuring have a 51mm. opening, but I'm planning on a 44.45mm. opening in the bottom of the adapter plate.

[Devastator]

Here's what I have so far for the bottom plate on a 600GSXR TB.

[Devastator]

There's an o-ring groove for sealing to the intake manifold and an o-ring to seal the TB against. Still need to add the relief for the throttle linkage pulley.

With the throttle pulley reliefs.:

Here's a model of the pulley for the TB , on the GSXR600, that lacks one on the correct side. This should put the throttle cables on the same side of the TB's.

I suppose these will be ready after Christmas? What's the ball park $$$$ I'm looking at for the plates and the pulley? I may have to tell the kids that Santa has to cut back this year due to the bad economy.

I may have to send the pulley I purchased from you back so that you can drill another hole for both cables. I'm kicking myself for not having it done from the first time around.

I was just wondering what the latest was on these.... I'm having trouble visualizing your pulley though

Probably after Christmas. Still have to design parts to plug the unused injector ports, and what looks lie holes for a choke? Also working ont the top plate as well as the throttle stop for the TPS side TB. Also looking at the fuel rails. Quite a bit of work to do still.

What's the ball park $$$$ I'm looking at for the plates and the pulley?

Not sure yet. It'll depend on on the quantity and how interchangeable the parts are between them and the other TB's I'm looking at.

I can make a different style pulley, and may, in fact, that has a stop pin pressed into it. I can also nodify the pulley I sent you to have another hole and stop pin. However, many cable set-ups have both cables going to a centered pulley, so you'd only need one hole.

I got a little tied up working this week, so I didn't get much time to work on them. The pulley I posted a picture of goes on the
tb that already has the stock pulley on one end. On the opposite end of that throttle shaft is a lever that presses the othe throttle shaft in the stock configuration. My pulley should clamp to this lever with a set screw. Gonna have to make one in order to design a clamp that will attach to it also.

[Vee Dub Nut]

Ah.. I see. Very cool! Looks like its coming together well.

[Vee Dub Nut]

Oh, and the upper holes your talking about plugging are from the removal of the upper butterflies that were ECM controlled.

[Devastator]

Ah.. I see. Very cool! Looks like its coming together well.

There's a pocket on the other side that captures the steel bracket also.

Oh. I wondered.

If you need a tester for the 06-07 600 plates and pulley's you can sign me up Looks like you are going to machine a much smoother transition then my ghetto porting job that I did on my bolt plates.

[Devastator]

Sorry I've been outta the loop for the last few weeks. With the holidays, fighting off a cold, and my DD breaking down, I've not had much time to make anything. But, I'm back on task now.
I am working on a pulley for the "left" side linkage. I need to machine one and try it out. The adapter plates for the TB's to the intakes are programmed and ready to be made. I'm still working on the top plates. Then it's on to the throttle stop.

[Devastator]

Machined the first 2 operations on the lower adapter plates today. I had a very small breakthrough from one side to the other that I didn't see on the model. This only happened on one of the plates, and I fixed it from happening again. The breakthrough is from the "sloped", (TB), surface to the bigger o-ring groove on the other, (manifold), side of it. Don't think it would be a problem if I didn't find it, but happy that I did. This is why I prototype.
