After getting my motor air tight from a bad crank seal i upped my jet size to a 280 main i noticed the bike idles back down slower than before. The bike has a fmf expansion camber,fmf shorty air box lid off and Vito Reeds my elevation is 1700 the bike runs greats doesn't bog at all what do I need to try next or is it perfectly fine? I haven't done plug chop yet!
 
float height correct ?
have you tuned the airscrew ? how many turns out ?

slow to idle suggest your pilot circuit is a little lean, try turning the airscrew in a little at a time, like 1/8 to 1/4 turns, allowing 15/20 seconds between turns to allow the engine to catch up to the new air/fuel mixture, rev it and see if that helps, keep going until it does help.
