change to a 15T front is the best bang for buck if u want to keep the top...
you could also remove the snorkel from the air box...(some may find the noise it produces annoying after removing it...)
steven??

32mm??!!haha...
seriously..i think 32 is too much for a 4stroke 125....28 is more likely....but if you can tune it up...then, hell yeah!!....
if you guys got the doe...go for keihin FCR28...have to order/import, though.
wish i had that kind of money to spare
i've always wanted to reprofile my cams...but i haven't found a gd(trust worthy) mech...popular mechs usually charge more...sometimes OTT...
