I just got all my parts in to do a head and cams swap for my KFX450 and was wondering if my stock fuel system is adequate for my aplication. My current mods are Fuel ATV intake and Dasa 13" pipe with the PC3. If head and cams is too much, will cams alone max it out? Thanks.

good question...you go first...honestly i think you will be ok, havent herd of this being a problem with any other F.I. quads. now if you go forced induction or stroker kit then there may be some concern

You will not max out the duty cycle with a pipe, intake, cams and head. I know a guy running a 507 stroker, pipe, intake, cams, porting and hi comp. I am almost positive he has the stock injector too. i will find out forsure this weekend.

Thanks for the input Fuel. That's good to hear. My next mod is definately gonna be 507 stroker with high comp. Do you know what kind of numbers that buddy of yours puts down?

No problem ........ i dont have the exact number, but remember all dynos read different. i do know its a monster and it has VERY mild cams. They are now testing some mid to high cams and i am VERY sure it will lay down some nice numbers. I will post some details as soon as i hear them. I think they are trying to dyno it this weekend.
