I ride mostly trails tight stuff. This year I put a 13frt 51rear sprocket and new mich s12 on it, which works great I want more power and was told doing a cam mod was good idea. After re shimming my valves I realized how easy it would be to do a cam change I looked at hot cams but the only ones I could find would lose a little bit of low end and that is not an option. my question is on my 04 450 what would be the best cams to use and has anybody done this. It seems to be cheaper than a big bore kit how does it compair. and will it make a huge difference or not.
