2009 Kawasaki kx250F - Tech Question please read

Okay so i use 3rd gear ALOT, and usaly am pretty high in rpm's most the time, i run novice. I was considering puting a HotCam (Stage 2) and a Wiseco Piston Kit Standard (77 mm)

first question, would that piston even do anything noticable for performance???? website is (http://www.rockymountainmc.com/productDetail.do?&navType=type&webTypeId=201&navTitle=Engine&webCatId=17&prodFamilyId=3784#vehicleSelect)

second question, would i have to change anything anything else if i put a racing piston in my bike? Like in cars if you add a turbo you need to change the pistol and a list of things??????

third question, anything else i should add for power (not an exhaust)

PLEASE REPLY WITH ANY HELP

as far as the piston goes, i would go with a new stock piston and new rings, the wiseco piston is heavier than stock and the bike will rev slower w/ that piston, and you wouldnt have to do anything special after putting a new piston in.

the cams are def a good upgrade, just get the cams that will boost performance where you want it.

Other than cams, there really isnt much to do for performance other than getting the head ported and polished and possible decking the head for higher compression

hotcams no!!!!!
