I've got an 03 KDX220 that I plan on installing an FMF pipe and silencer on. I figured I might just replace the OEM piston with a Wiseco while I'm at it. Are there any special tools needed to remove and install a new piston and rings? I've never done a top end before but I've got the manual, is it preety straight forward for someone with reasonable mechanical ability?
