It is not uncommon for the rear brake to drag some immediately after being readjusted. Newbies tend to tighten the rear brake up too much when they adjust it and this can give you the "sluggish" feeling.
The rear brake on the savage also tends to accumulate some brake dust as wear occurs and it requires a little extra adjustment slack to keep the dust from giving you that momentary "dragging sensation" if the rear brake gets a bit wet from going through a puddle, etc.
Of course, you guys are fortunate, you can wipe off the brake mud formed by the addition of that splash water with your underwear that you just took off ....
The rest of us just aren't that skilled, we have to stop, put it on the sidestand, get off and then loosen our rear brake adjust nut by a turn or two.
