the 904 ups the compression which is where most of the power increase comes from. the forged pistons are much stronger than the stockers so high revs will not be a worry. cams, who knows. i am sure you will notice a difference even without them. also they are easier to change than the bb kit. you could always do the bb and then throw cams in when you get the money, or wait it out and find some 790 cams. guess it comes down to more what you want out of the bike, and how much you want or are willing to spend. decisoins decisions
