i'm looking into spending 50 bucks on a stage 1 dynojet kit for my '04 450 foreman. the web site doesn't say howmuch of an increase one should expect. has anyone installed this kit? was there a noticable increase?

 

It really depends on what else you've done to your quad. Jetting up with no exhaust or intake mods (new pipe, filter, etc.) won't do alot off anything. Dumping more fuel into your engine won't boost the power any. It has to breathe as well as drink, and if it drinks more than it breathes, it will choke.
