Where can I buy a set of stage 1 came, haven't been able to find them anywhere.
Also I have been looking into a power commander, is it worth it on the f4is?

 

Never heard of stage 1 cams. Do motorcycle companys think people can't read cam specs? HRC might have cams floating around out there but they won't be worth the money they'll cost. And power commanders aren't for power, they are made to keep the a/f ratio correct. So if yours is off, then yes pc's are worth it.

 

Power commanders can change improve throttle response times and adjust to many modifications if I'm.no mistaken. And a friend of mine told me that there are the different stages of cams you can.get and their worth it supposedly.
