Yep, the JE 416 piston is domed and has those big valve clearance circles; the stocker is flat and just has those little notches. Plus the 416 piston obviously has a bigger O.D. The rings on the JE piston also are thicker and more "heavy-duty".

Well it's nice to see a pic of a JE 416 piston,,,I've had my piston for about 3 weeks now and it's still in the box ain't even looked at it,,,,along with the cam, gaskets, valve seals, etc. etc. etc. What the heck am I doin with all that stuff still sittin around,,,,:huh I'm a loser..:D

Its looks similiar to the je 10.8:1 stock piston I just installed. Now quit taking pictures of your parts and get that thing put together!

i recently put a wiseco 11:1 piston in my 400ex, like the JE the wiseco piston seem to be very well made, the oil ring is about two time bigger that the stock, the small hole behind the rings for oil are much bigger too and the piston is more light than the stock.


Hey Rico, i dont know how can you wait with all the piece in your house!! the difference is awesome, it's like ride a new atv!
