I have an 03 kfx400. I was thinking about replacing my piston with a wiseco high compression piston. I was wondering whats the benefits with the 13.5:1 high compression piston? And any other mods required? Also do you know of any step by step videos on how to change the piston? I have a service manual with step by step directions, but I'm just trying to get a few more to look at. Greatly appreciated.

changin the piston isnt that bad the downfall is you have to get new rings but with a new piston you should get a set but then you have to buy a new head gasket but other than that you dont have to have any special mods but i dont kno how much you could tell if its all stock but if you have an exhaust and jetted you should be good to go

My piston rings are shot anyways. So i figured I'd just spend the extra money and get something good. Anyways, I figured thats all I needed was just a new head gasket. I have an exhaust and it's rejetted, but thanks alot for the input.
