Still rebuilding. Swapped the MC21 swingarm out for an MC28 (Thank you to the Tyga folks for tech advice on that). New chain, all is good. I adjusted the chain by rotating the toothed wheel on the LH side of the swingarm. It worked, but not sure if that was the correct way to do it. Loosened the large pinch-bolt before rotating it, of course.
I really did search the forum before posting this....

Thanks
Jeff

Yep, that's it!

Jeff,

That's how you do it. Make note of chain tension in the future. For some strange reason, I find myself having to readjust it regularly. An Ohlins (or other) preload spanner works much better than a large screwdriver and hammer. Don't ask me how I know......
