Need a little more info to be able to truly help, any mods to the bike? Has anything else changed or been done to the bike recently? You say "seams to lag power" does the RPM still rise but at a slower pace than normal? Did you recently refuel the bike? how long has the bike been acting this way?
With current info I would start with basics, check air filter, maybe get some new fuel if its something that just started happening.
