Hi everyone this is my first post. I have an '03 Foreman 450ES with 3800KM that is all stock except for stock size ITP Mud-Lites and a Warn 2.5t winch. I just installed a Dynonet kit with the needle and the DJ126 main jet, along with a K&N filter. Prior to the jet and filter i could easily hit 82 Km/h or more for top speed, but after im struggling to break 80 Km/h. I notice the extra low end punch but I thought I would gain top end power as well. Do I just need some tuning or is this a trade off with these mods?
Also do the slip on exhausts like the HMF utility and the FMF powerline really live up to their claims of 7HP and such?
Thanks
