tru 440 piston

[IRONMIKE113]

who knows where i can get a tru 440 piston? i'm hearing that je piston really is a 435.:(

[trx400EXtreme]

most of them are 435's. a true 440 is 89.5mm and a 435 is 89mm. if your looking for more power i really doubt a true 440 is gonna make a difference over the 435.
