Oil in airbox! & MPG way down
My first question on here! So I was on the last leg of a 3000km ride, getting 300-350kms out of a tank consistently.
Filled up and immediately my display showed a dramatically reduced range, I figured bad gas and that it would sort itself out. So another 800 kms later I'm down to about 200-250kms per tank consistently, the bike seems to be running fine though.
I did an oil change yesterday and generally gave the bike a once over. The only strang thing I found was oil residue inside the air box, the air filter itself was perfect, no oil residue inside the pipes leading into the throttle bodies.
So where did the oil come from? Is this a concern??
and what happened to my fuel mileage??
