I'm looking for a tachodrive gear/ washers x2 / retaining circlip to fit a 1000/1200/120 degree 3 cylinder. The original one has disappeared into the ether during the rebuild of my RGA Jota...
 
Something doesn't fit here...

Only the 180s and the Jota 120 had the gear retained with a circlip, the 120° RGS-based models used a screw-in bush similar to that in the speedo drive housing.

A pic of your cam cover would help.

I could help you out with a gear for the 180/Jota 120.

PS, I think we had already established you have Jota 120 cams fitted.

My phone's broken down, so can't furnish photos, but I can confirm that it's the earlier Jota cam cover and the drive is off the rear (inlet) cam. I cannot be certain that the engine has had an earlier head fitted, along with the Cam cover, but it could be a possibility; I have some receipts in the bike's history for cams.
