That's what I'd do....
You don't know how long it's taken for those deposits to build up.
Deposits are normal. No matter what your lubricant. You have metal grinding on metal thousands of times a minute.
On new engines, it's very common indeed. That's why you have a 600 mile service. To flush out all the crap. New bikes are usually filled with a different type of oil to help this process. (or cheaper)...
If you ever changed the oil on a BMW, you get swarf every time. Especially in the gear box and the rear wheel drives even more so. You'd have a heart attack if you paranoid about such things.
However, being an older XT600.. Those 5th gear problems would have me guessing.
