just wondering.....if you look on larrys site you can see the picture of the wiseco piston when he first gets it, and then after he sands it down. i was just wondering if you could apply this same logic to sanding down the sharp edges on the je pistons....would it work just as well? negative effects? hmm just a thought.

 

JE, Toda or any piston that has sharp edges. Just be conservative. Check out HXguy's post.

 

yeah....use like 600 grit? something really fine... ?
just slightly.

 

sharp angles and edges get extra hot, smoothing the edges a little battles against detonation
