I don't think "worse" is the correct word, I would say "more user friendly for every day use". FZS / 6 are not intended as a track / sports bike, so they "de-tuned" the engine to produce its power lower down than an R6 or thundercat or whatever but still perform reasonably well when used for mild sports use. This makes every day riding easier and the bike feels a bit more powerful at normal speeds and lower revs as a result of softer cams and different carbs. More of a linear power curve. On a track though the R6 engine makes more sense of course as you will be ragging it and it and the fact it revs higher means more hp etc. Thundercat (probably R6 too) has ram air which also helps on a track at higher speeds, otherwise it isn't really a lot more powerful than the FZS. I like the idea of the thundercat, I just hate clip ons. I would think selling your FZS and buying an old thundercat / R6 would be cheaper and safer than taking the engine to bits to make it more like one of them. More power requires suspension upgrades too.
