04 piston

hi got a 02 crf450 doing topend piston rings etc .thinking of putting a 04 piston kit in and going oem with it.is the oem 04 piston a higher compresion than a 02 .

Yes, starting in '04 the compression was kicked up to 12:1 as compared to 11.5:1. Using an '04, '05 or '06 piston in an '02 and '03 bike is a nice performance boost over stock.

I sure as hell hope it works. I just put one in my '02. Haven't run it yet. The '04 piston has even shorter skirts than the old one. I'll post a report once I let 'er rip!
