Items #14 and #17.
You may be able to use your items #4, not sure what all you've got.

You can buy a set of hubs and screw plates brand new for ~$100.
A cursory check of parts catalogues showed that ~'01 and after have adjustable pulleys.
Yeah, my brother's 2001 M900Sie has them. One less thing to buy for him.
If you could find some.
What about getting someone to adjust the timing with oem steel pulleys offset wd keys?

I want the bling.
Thanks Speeddog, I was already accounting for those. But you were calling them hubs and I was calling them flanges.

Vee Two now operates from home on Ebay. He might have some. I got my Vee Two pulleys from Brad. I don't know if he has any left.

I'm going to try to revive this thread to see if anyone can guide me here. I have a '95 M900 Engine with fixed pulleys. I bought a set of adjustable from Desmo-Racing (
http://www.desmo-racing.com/en/ergal-split-belt-roller-timing-kit-ducati-06-xml-245_457-1621.html
). My tech is attempting to install and we are running into an issue. When the pulleys are seated there is not enough thread left on the shaft to secure the nut. Does anyone have information on what we need to do at this point? Did I miss something in this thread that contains the secret!? Many thanks to any guidance.

Looks like it's still got the thin backing plate from the stock pulley on there.
Doesn't seem to need those.

Does the centre sleeve protrude about 5mm too much? If it was flush then it would allow the nut to clamp both it and the pulley face.

So should all the torque seat on the centre sleeve and it therefore be proud of the pulley face by a mm or 2, or should it be flush or recessed a little? I guess aftermarket being alloy pulleys probably means the torque should go into the steel sleeve? I may look at some M900 heads to see how the oem is set up.

His pulleys have a counterbore on the back side of the center hub, lookes ~2mm deep.
That, plus the OEM flat plate (that's not needed with these pulleys) ~1mm thick.
So then the snout of the hub would be ~3mm further out than it should be.
And that's about what it looks like in his pic.
Here's the back side:
Nut is supposed to pinch the hub up against the spacer that goes through the seal and up against the bearing on the cam.
Not supposed to pinch the pulley or the little front plate.

Looks like that counterbore should be deeper and particularly if you want to run the guide plates.
Have you contacted the vendor?
