My '07 Foreman 500 ES manual has this
1 3/16 to 19/32, TOW OUT, front of wheels greater that rear of wheels. No load.
I'd like to send you the whole page, but the file is "too big"
If you have an email, maybe I could send you the page that way. It is a .pdf file
I don't know why they have a toe out, maybe with the operator it comes into a toe in.....?
