This Clymer ATV repair manual is a little expensive at just
over 30 dollars but pays for itself when it guides you to fixing a
problem.
Almost 500 pages of
impressive technical details seems to cover just about any problem that
might happen, along with a comprehensive troubleshooting section that
can often save huge amounts of time.
It's already helped me twice
by pointing out a
quirk in the way oil is added to a Polaris 700 ATV. The other way was recently when
I used the fuel system diagram to track
down a leak.
