Oil

[HondaEXrider22]

What thickness of oil do you run? WHat better for colder monthes like these? I have Valvoline 20W - 50. Is this good?(03 400ex and 03 250ex). Is this good oil? The colder weather the thicker oil right?

no you need to go lighter like 10-40 your oil will thicken in the cold.

Are u running the ATV valvoline oil, if not its not good. i don't know about the 250ex but car oil is bad for wet clutches. In my 300ex i use Honda HP4 20-50 in the summer and 10-40 in the colder months. If u don't have a way of getting the honda oil, i've heard of people running mobil one red cap with wet clutches.
