Bike has 13,065 miles at UOA and oil was changed. Polaris completed UOA.
Still using FP Plus and Bio Plus fuel additive 50/50. OEM oil and air filters.
The mail man lost this sample. I sent on 9-2 and they recieved on 9-16. Lots of things different for this sample. Fuel @1.7%. I did clean air filter at this oil change. I will check plugs. I have never seen Tin or Potassium in any of my HD samples.
Would Visc. be up with fuel @ 1.7%? Would you be able to smell gas in oil at that percentage?
Polaris flagged as a 2 which is for observation for high magnesium and high Visc. Magnesium was lower than previous samples.


Any comments or suggestions?

The wear numbers look great. It does look like you have a fuel issue which could cause the oil to oxidize and raise the viscosity.

I wouldn't worry too much about the tin and potassium, but just watch them.

What treat rate are you using the 50/50 fuel additive?

1/2 oz. per 5 gal. at every fill up.
I did replace plugs and clean air filter not much else I can do because of fuel injection. If fuel is still high at next UOA I may look at installing a race tuner and have it dyno tuned. Total cost would be $600-$700 a lot of money for 5-10 more HP. That's HD for ya.
Where would the potassium come from? Everything I find, potassium is a coolant additive?

At 3 ppm, K could be from anywhere really. That is such a small amount. Could be from outside dirt in the crankcase, the fuel, or even the virgin oil itself. Just keep an eye on it.

I was just curious. Never seen it in HD samples.

Thanks, Pablo
