keep your bike within 4k rpm on the tacho until the 1st 500kms, then 5k rpm for the next 500 and then 8k rpm until the next 500kms. after that rip the way you want.
use only the below mentioned engine oils:
Minerals: Motul 3000 4t (for the 1st 5000kms)
Semi-Synthetic: Motul 5100 (for the next 5000kms)
Full-Synthetic: Motul 300V (if you don't wanna switch to full synthetic, no problem, but if you wanna switch, then don't unless you've scored atleast 10000kms with the new engine)
many of my friends use
castrol activ 4t xtra but i would suggest you not to. castrol is not well suited for a
dtsi engine.
another most important thing,
never go downwards in the engine oil hierarchy i've mentioned. If you start using semi-synthetic, never go down to minerals ever, similarly if you're using full-synthetic, never go down to semi-synthetic or minerals, no matter whoever says what. engine life gets hampered massively.
