Ok, the cam chain is on, and I am very confident I got it right but here are some photos, just to be sure.
I went back to a Regina, sent the DID back to Dan at Motoxotica, who was very nice to take it back. I'd rather use the Regina because of the reusable master link. I have used a Regina until then with no issue until I wrecked my top.
Breaking it to 66 links was a bit of a pain, with the Dremel and a cheapo chain breaker made in Taiwan, but that's just me trying to save $ and sweating the little things in return.
I had to do some work on the tensioner lever, since the new bushing has some sort of a peg at the end and that as well as the 13mm hex nut at the end needs to be ground to fit in the old top. Still, it is a much much better bushing that the previous part. Upgrade very worth it.
Check the photos... They speak for themselves.
