Hey, i gotta 2004 yamaha blaster a week or 2 ago and the guy told me it was recently bored .40 over with a wisco piston in it and ive been really curious at what size displacement it has now. ive been hearing guys calling a .30 over bore a 240cc which is really starting to boost my interest. Thanks -DerekAndersonRacing
