Just got my bike a month back. Changed the oil to Synthetic, changed the oil filter as well. Changed the air filter to a K&N. Changed front and rear brakes. The back tire is almost bald, Will be putting a new one this week. At approximately 940 Km the engine was showing almost empty on oil. I bought a Mobil1 off Canadian tire 19$ and put in 600ML. Just waiting to see if it happens again. Any idea why would it be burning oil? Would a thicker oil Help? It says 10W 40 on the oil Cap.

Also on the highway, any time I go above 110 it starts to tremble. MaX speed is 200, i dont see why a 500cc would act like this, I can imagine it trembling at 180Km/h but at 110..... Also the 5th gear maxes out at 90Km, is this normal?

Thinking of taking it to the mechanic. Any idea what could that be?
