who makes the best cam's and do u need a bore kit? do u recomand them for more horsepower

 

Though i'm no expert by any measure... but
a "hotter" cam in most basic terms.... extends the intake stroke.... aka more fuel gets dumped in...there by getting more bang everytime.... though there comes to a point where you can only stuff so much fuel in....

are you considering an upgrade?
if you are all stock a stg 1 and jetted and piped... anything else in my opinion would not be real necessary...
if you are going w/ a big bore then stg 2 or 3

as far as brands.... i know a number of guys who threw hotcams...(wiseco) at their bikes..
you couldn't go wrong w/ trinity racing cams...
and if you are ready to throw down some serious coin check out duncan racing's stuff...
