Since the previous owner of my 2008 WR250X removed the air filter at some time in the bike's history, I decided to do an oil analysis on my latest run of oil. This was a fairly quick change, paranoia, because I was hoping to flush out any contamination that might have been trapped in the oil. While I was draining the oil, I captured a bit of it and sent it to Blackstone Laboratories for analysis. The results are either confusing or depressing. Neither I or the analysis tech can decide which, as yet.
I'm wondering if anyone else on the list has had their oil analyzed?
ALUMINUM 31
CHROMIUM 1
IRON 27
COPPER 95
LEAD 2
TIN 0
MOLYBDENUM 81
NICKEL 1
SILVER 1
TITANIUM 0
POTASSIUM 2
BORON 176
SILICON 10
SODIUM 4
CALCIUM 2310
MAGNESIUM 16
PHOSPHORUS 1427
ZINC 1534
BARIUM 2
The tech's notes were: "Aluminum, copper, and silver were on the high side in this first sample.
Universal averages show typical wear levels for this type of engine after about 850 miles on the oil.
Aluminum shows piston wear and copper is from brass/bronze parts. It's hard to say where that silver is
coming from. We've seen silver from bearing cages in some bike engines."
