It seems to me that after draining all oil and filling with fresh oil that some old oil is still in and mixes with the new causing its color to darken, after 500 miles the oil window shows considerable oil darkening.
The filter is K&N, my riding is surface streets, I have no oil consumption at all, after 2000 the oil level is the same as when I changed it.
the compression is good @ 166-170.
Is this normal? or is it blow by? causing the contamination of the oil?
the oil does not come out black but much darker than new.
Should I be concerned? or this is normal.
I once asked the service manager at the dealer about using the K&N air filter and was told the stock filter traps more than the K&N, I used K&N anyway.
Thanks for your input.
I did a web search and found out this.
Bad Rings: air will blow through the oil filler when performing the leak-down.
Bad Intake Valve: air will blow through the throttle body when performing the leak-down.
Bad Exhaust Valve: air will blow through the tailpipe when performing the leak-down.
