modules
on the site at atv connection they were talking about alot of different cdi modules ,they said that they were getting about a 25% horsepower increase. They were talking mainly about modules for the V force but I am sure the prarie would work also . The unit from Four Stroke Tech sounded like the best setup to me. Go to their site under Kawasaki and look around abit and I'm sure you'll find it . There is a guy posting info there that is just incrdible- he is really sharp. The posts are really long and very informative.
