Yes, sometimes bike seems great but sometimes not(honestly). Last time kixx 4t 10w-40 did well with good economy but after 500 km it is not same. Thinking to try Shell 4t 15w-40 or some other thicker oil for summer. So far plastic covers are concerned i have not tried much as yet. After 19th June, i'll b little free. I plan to sesrch the covers then. If u have some suggestion, pls tell.
