If the goal is to make the bike run better complete the package. Fixing the input and output is great but you have not completed the middle bit.
The Engine is a basic pump suck air and fuel in compress it and exhaust it out. the middle bit I am taking about are cams. Oh no bad word, too many $$$$$$, voids warntee, yada yada yada.
Cam setup in the EPA Vic along with the retarded timing is designe dto make the motor run hotter to help rid the offending fuel based bits. Advancing the timing alone will help make the bike run better some have added+4 some all the way to +8 degrees of advance. Next step is to swap the cams to more efficent onces. Lloyds Drop in or Touring cams work great and help much with drivability.
".. But I don't ride ablve 4000 RPM..." that is fine, the cams also help build smooth power from idle all the way up. I routinely run 6th great around 1800-2300 rpm with out lugging issues. Longevity,KMC installed and dyno'd the bike at 17,000 miles and I now have over 40,000 without a single hicup.
If you are looking to make the bike efficent do not over look the cams and dyno tuning.
