Ditch the rev
If that is still the original needle and seat, replace it.
While your in the carb
doing that, find out what Pilot
jets are in the carb.
Check the PMS
screw for how many turns out from lightly seated it is(see the Tech Articles above). Shouldn't be more then about 2 1/4.
Find out what groove the clip is on, on the needle, and what is under the clip. Should be a fat plastic spacer and a silver shim(washer)
The Hyperchargers get bashed on here a lot. For whatever reason, the Hypercharger folks thought messing with the air and the fuel was needed. If who ever installed the Hypercharger followed all the directions, they probably changed out an air jet, which makes the bike run richer, as well as over jetting the carb in the Main circuit, and on the needle. Find out what those are, and let us know.
I can't help with the furniture.
