It would be hard to find all the parts you need to convert it back to stock—both primaries, basket, inner hub, starter ring, chain ans much more. I had a Karata on my K9 and had ongoing clutch problems, so I took it off and sold it. But— I had the parts to go back to an OEM primary (thank you Trainman). Do you by any chance have the original primary drive? Maybe try to find a salvaged bike, get what you need and part it out? I recently tried to find an inner primary for my 08 K9 and couldn’t find one—they do come along from time to time, and unfortunately keep getting more expensive. HDM has none and the last price was $599.99 for the inner primary.
Another thought…Knothead mentioned a ‘hack’—didn‘t recommend it tho—-that you can get extra life out of a worn clutch by adding another steel disc. The object is to restore the clutch pack stack height.
I had a used clutch pack from my Karata that I sent to Forum Member BDM7250 because he has a Karata and I figured he might have use of them someday. Look him up and see if you can negotiate a steel disc to keep you up and running while you look for a permanent solution.
