I bought my 2002 Honda 450 Foreman ES from a buddy who had it registered as a 2003. I recently ordered a 2003 owners manual for it and after checking out the wheeler a bit more realized it's a 2002. So now I have a 2003 owners manual for a 2002. I'd like to give it a good once over and change fluids, etc. Are the manuals interchangeable or were there major differences between 2002 & 2003? Any help would be appreciated. Thanks.
