Thanks for the help guys.

Bit of an update. Drained oil again this morning. Exactly as per handbook. Bike now has 2.6 litres in.
Checked the level after short ride (15 mins) and was showing a little under MAX so topped it up so it was just over MAX.

Went on a decent 80 mile ride today. Dad rode behind me at 80, no oil burning smells coming out and exhausts same as they have been.
Did a compression test this morning. Reads 100psi which is manufacturers guide for max reading. Spark plug still looks good. No oil in coolant for sure. No oil in airbox for sure.


From what we can see there is DEFINITLEY no visible sign of excess burning oil.

When I got home from ride I stayed on the bike and waited about 5 minutes for oil to settle. Took a reading and it read a bit below the max line. (less than this morning but I guess its going to be hard to get such an accurate reading.

Going to ride the rest of this week every evening. DO same 10 minute trip, check oil. Ride for half an hour - hour then check again. Will do this as many times as possible before I go away just to prove if it consistently drops or not.

I think I have my self a mystery. Possibly over complicating things worrying about having the issue for the 2500 mile trip :/

Is it worth taking it to a Yamaha dealer to confirm its ok?
I'm sure this will be stupid money!!!

I'l keep you updated.

Cheers again
