Just bought an 2007 CRF 450 and I hate to ask becasue I know I'm gonna start a Sh*# storm but.... What oil is recommended for the 07 CRF 450? I have two local shops and one said the Honda HP4 oil (w/o Moly) and the other said the HP4M (w/ Moly). Go figure the manula says both as well. Any suggestions????
