Hi all... I, like everyone is interested in keeping the bike (WR450) with the best oil. This meter I bought will let me choose the service interval. I just do trail riding and no racing at all, so with that in mind, my question is what would be the best interval?? I have read alot about how many miles or Klms but nothing specific in hours. If there is it seems to be "racing hours"... Can anyone help me out here?
