Hi guys.. I´ve searched the forum to avoid asking the same thing, but dind´t find a definite answer.
Right now I´m using Quaker State SAE 15W-40 Racing Oil (car oil) in my bike, and it´s time to change it, so I want to try a better oil this time (misshifts happen some times). What do you think would suit my bike best? Semi synth, or normal motorcycle, or just keep using the same? And what brand u katana owners recommend?
Thanx a lot!
