Bhai yeh manual k chakkar myn parey na to you will be in trouble and soon you will getting lines on your piston.
Yamaha is best suited with only 20w-50 oil and api you can use any if available in motorcycle oil means JASO rated.
I wasted almost 2000 rupee on different engine oils and finally settled myself on SHELL AX3 20w-50 which I found best so far for this yamaha motorcycle.
Anyway, I do not recommend you to use any specific oil. You can use any oil from any brand and then can share your experience here.
I finally got rid of that tik tik sound. I just right the exhaust tappet near 12. Fuel average is better than before but RPM isn't stable like I want it to be.
I will visit Bilal ganj tomorrow to get special tool for mixture screw setting and also will get tappet T to hold the tappet at specific position during tightening. Previously used plier but this is not effective.
