dont run it lean. less fuel = less lube = ruined top end and possibly rods, crank etc ( i didnt do a plug chop on mine and i let my brother ride the day after i got it and i found out it was running lean the hard way :: ).
21 or 22cc domes should be good for pump gas and yes ditch the boost bottle and put the crossover tub back on. everybody on this site will chastise you pretty bad for even admitting to having a boost bottle. :thumbsup:
