After a couple of years of assembling a Jota from boxes of parts and after many strange setbacks I have it running and registered but not drivable.
The shifter linkage is non functioning - giving me only neutral and first. I let it all sit for awhile figuring I had a frustrating bunch of attempts at adjusting the eccentric screw before me.
Now with the change of season, I started at it. Drained the oil and took a long look at the mechanics, figuring I might be missing something (washers, etc).
It suddenly dawned on me that something was very wrong. The selector hook was on the right side of the selector drum and all the parts diagrams had it on the left (towards the year of the bike - teeth facing forward).
I realized that somewhere in the distant past (the bike had been apart for over 30 years and the motor was rebuilt maybe 15 years ago) the selector mechanism from a twin was installed - what Parker calls an open shift drive. They are not interchangeable.
So I need:
The gearbox rocker shaft (40117080]
The selector lever (43307002)
The selector lever pivot (34220410)
And the spring (50190218)
Does anyone have these parts that they are willing to sell? The shaft and the pivot are the hard to find bits. The hook and the spring are available. I have a perfectly good setup for a twin that I won’t need and would be more than happy to add in as part of a transaction to get what I need. (See pic).
This is what I have, not what I need
