I race with mine so I like to change mite often, better to do maint. than a rebuild and a DNF. So I'll change mine after like four races thats around 400 miles of desert racing.
Don't know if I need to do it as often on the 700 will be talking to W.M. tomarrow and ask him about it, that was on my Yamaha yfz450 changed that often.
