Okay,... I'm really cheap, so take that into account... (if you buy $300 mufflers, $400 shocks, and $150 handlebars, ignore this)...
... but,.. bumps have to be added material, likely bug guts... buff them off... 0000# steel wool at most, try cleaner first..
Pits,... may have cratered edges from pebbles?... smooth them with wool...
Bumps will buff off,.. and craters, with edges smoothed won't cause any more damage.... maybe some light weeping...
If the weeping is too severe,.. you need tubes...
But,.. I'd try it.... 'cause I'm cheap...
Did I mention,.. that I don't like to pay a lot?...
