K&N - Straight exhaust - jet kit
My understanding is all of these things are needed for the bike to still run properly. Any 2 without the 3rd will made it run bad, but all 3 is best bet for it to still run good, but will require some fine tuning. Is this correct, or am I barking up the wrong tree? And even if correct, would it be worth it for the power gained since I'm not sure how much power would be gained anyway.

Where are you getting this information from? I've never put a pair of slip ons on a Superhawk that caused it to run worse (I have caused nasty flat spots swapping mufflers on other carb'd bikes). Keep in mind the bike ran properly in the first place and they're now getting older and the chances of coming across a used one that's in various stages of neglect and disrepair is much greater. Yes they will run even BETTER when PROPERLY jetted, but any Superhawk I've ever owned ran fine with stock jetting and slip ons. You can do your own research on here with regards to the K&N but I don't think I've ever actually heard of one being NEEDED to make the bike run properly or better.

Slipons should be no problem, other then potential occasional popping noise on decelerating.
Before you do anything else, I would highly recommend to read and research on the forum on what works best, VTR's could be very tricky with the carb's setup and air filters.

I got mine dynojetted, plus K&N when I got rortier cans fitted many moons ago (2001). It cost quite a bit mainly for the dyno time, plus the increase in fuel consumption.

wow, that isnt much gain at all. what a waste these days
Look at how the bikes these days are upwards of 200 hp from 100 two decades ago with nearly the same size engines. just differences in tuning to gain so much. makes me wonder if they're actually holding back on some engines and models.

you may want to put 48 pilot jets with slip ons, and maybe play with washers under needles, thats all you need. With KN filter, there is more tuning involved, and the best results are together with DJ needles. You can achieve about 108 hp on rear wheel. But opinions on this vary ...
