Big Red Piston Question

[ZacH_GrifF]

Im freshening up my 85 250es and need to know what piston to go with. Has anyone had any luck with the Bikerchick overbore pistons? Or what about the WSM pistons? Im going to probably bore .010 or .020 over depending on what machine shop says. This will not be a hopped up motor, I just want to have a good reliable running motor. Honda doesn't offer the OEM pistons anymore and I don't wont to break the bank on a NOS piston either.

Dont fret about it. The ES motor is pretty tame and as long as the piston is sized to the bore correctly, you will have many years of reliable fun. I've bought the Bikerchick pistons and have no issues with them.

The last 3 trx300 4 wheelers to come threw my shop needing a top end I went with a Numera piston kits and i'm pretty impressed with them . Very similar motor to the 250es .

I just looked the Namura pistons up and they don't offer the trx 250 pistons yet and don't offer atc 250es pistons either, thanks though.
