Looking into a rebuild for my 03 400ex because its about time...

going to put a stage 2 cam in (probably hotcam)

looking for a good piston company to run with too

i want to run pumped gas so im pretty sure it has to be 11-1 compression or lower???

ive looked into it and this is what i got so far..

CP Piston- 11-1 for about 180$
JE Piston- 10.5-1 for about $140
- 12-1 for about $160
Wiseco Piston- 10-1 for about $120
- 11-1 for about $130


so what should i go with so i can run pumped gas but get good power?

i know you can still run pump gas with 11:1 not sure about 12:1 though
