have 850 XMR. what is the best oil to use. will 0w40 work. and do I really need the BRP oil.. the mechanic I go to said he puts Mobile 1 Syn 0w40 in it.

is that good oil??

also I heard lifting a bike isn’t good and causes more stress on parts. However, would a 2in lift cause any stress at all or would that be ok.. just to have that little extra clearance.. I have the stock 30in backs.
