It seems that the KFX takes well to the Big 3 Mods (exhaust, intake, PCIII with proper map usually gaining from 8-10HP), but after that with the addition of cams, head port and polish and ignition it seems like a margin of diminished returns. I've seen many dyno charts in this and other forums that show a 2hp gain with cams. For nearly $350 for cams, plus the hassle of installing them yourself or paying an additional $150-$200 for a shop to install them, it just doesn't seem to be worth getting the cams unless you can get them at a good discount and install them yourself.
As for the ignition, I have read much and found very little in the form of getting one (CDI) for the Kawi. It seems to have very little performance gain for several hundred dollars. Finally the head port and polish seems to do the same or little more than adding cams.
Overall, spending $350 for cams, $250 for an ignition, and $250 for port and polish plus any shipping fees and installation for the cams if you don't know how to do it, and you are paying anywhere from $850 - $1100 with tax and everything to gain about 4-6 ponies. Also, you will need to get your bike dynoed and mapped again with the additional 3 mods which costs an additional $200. You may actually pay $1200 for a 4-6 HP gain. That just doesn't seem worth it.
I know some people get new pistons and up their compression to 13:1 or even 14:1, but now you are definitely reducing your engine life. I'm sure even with the addition of cams, ignition and head work you will also shorten your engines life.
Does anyone have any input on the differences truly gained with the addition of cams, ignition and head work? Is it worth the steep costs, hassles and shortening your engines lifespan to gain an additional 4-6HP? Let me know what you think.
