I just purchased myself a 199 YZ400F (I love it by the way) and I have some questions about adjusting the rear shock's race sag. Is it true that I have to remove the entire sub frame before I can get to the shock to adjust the sag? If not, Does any body know of a way to adjust it without removing the sub frame? and Last..... if I wanted a shop to do it..How much is the normal charge for adjusting the race sag? thanks for everybody's Help!!!!!
