833 making odd noise in 2nd gear only

I bought/installed, a Passon alloy box; Problem solved.
The tail is the Alloy GVod adapter and the cover is also Passon/alloy. that just leaves the retainer as non-alloy. I did put it on the scales but I forget the assembled weight; maybe 85 pounds?
With the line up pins, it comes down/goes up, no fuss. I even leave the oil in.
I suppose, to be truthful, I should mention that the last time I lobbed it in there was 2005ish, so I was 53 then. But I also gotta say, I was a fat lazy bum then. Since that time, I have trimmed down, built some muscle, and I feel that I am easily as strong at 70 as I was at 53.
However, I am not gonna make a run at my record any time soon, lol.
