Steve, I'm looking at the test sheet now. It says the oil was Castrol 5w40. Was that the Castrol motorcycle-specific stuff? There is a Castrol Syntec of that viscosity, but as far as I've seen, it's only sold at VW dealers (it's a special blend for VW diesel engines).
Viscosity is down a little, but it's not bad. Fuel dilution is good. No antifreeze is also good.
Lead, tin, copper, and zinc are found in Babbitt plain-bearing metal (crank and rod journals) and the bronze bushings in the transmission. Zinc isn't useful for analysis, though, because it's an ingredient in the oil additives itself. Lead, tin, and copper are all low - good sign, means low bottom-end wear. By the way, the lead number is not useful for an engine that has been driven on leaded gasoline.
Chromium, molybdenum, manganese, and iron are ingredients of alloy steel - crankshaft, transmission gears, camshaft, cam followers, stuff like that. Iron is found elsewhere, so it's not useful. The others are all extremely low - again, low bottom-end wear, a good sign.
Aluminum can come from pistons or from the camshaft journals, since the camshaft runs directly in aluminum on this engine (as with most other bike engines). The iron that's left is likely piston rings, but it's pretty low.
Silicon comes from sand. Low level means your air filter is working OK.
Calcium, phosphorus, zinc, are oil additive ingredients, part of the oil itself. OK.
The somewhat high aluminum is the only concern I'd have with it.
Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!
