generally speaking if you want more power, buy a liter bike. modern I-4 liter bikes arnt much heavier than their 600 counterparts and some can be had for around the same price as a sixxer.
that being said motor work isnt pointless. it isnt cheap though depending on the extent of the build. however it isnt necessarily a sacrifice to reliability. horsepower is expensive. a bike right out of the crate usually has some compromises to fueling and exhaust in regards to emission and noise regulations so its easy to free up anywhere from 2-10hp depending on the bike, with pipes and a power commander running a good tune. anything beyond that and your looking at lots of money for marginal gains. especially if you arnt able to do the work yourself. its not the parts but the labor that will kill your wallet.
ive done a couple 1000cc vtwin motors with JE high comp pistons and some cams from WebCams. i ended up gaining around 15 rwhp after it was all tuned. i did all the work myself though so it was only the parts i was paying for and i really did it mostly for fun.
a stage 1 type motor build with a full system, power commander & custom map, high comp pistons, and a set of cams would be sweet on the cbr and if done right would be no less reliable than a stock motor plus you could freshen up the motor while your in their and replace all the bearings. but gaskets and rings and everything really adds up quick and then labor on top of it all if you cant do it yourself and your easily talking about a serious investment.
if you really want more power sell your bike and buy a 1000rr. much easier. although personally i am of the opinion that 99 out of 100 guys cant ride a cbr 250 to its absolute limit, much less a 600. then the guys who think they need a liter bike because the 600's are two slow are really dreaming. plus most of these guys have never set foot on a race track, so i would love to see where it is that they are at the limits of a 600 on the street. the fastest ever time at willow springs big track was set by steve rapp 15 or so years ago on a 749RS. granted that 749RS is basically a full factory race bike putting out around 135hp to the rear wheel, but still it is not a 180rwhp 1299 panigale with all kinds of electronic rider aids. point being is that going fast has a lot more to do with a properly set up bike and the rider on it than it does to do with power.
personally id invest that money in my suspension. really well set up suspension = confidence. confidence = fast.
