Y303 Spec???

[tjm73]

I can't find the combustion chamber cc spec on the Y303 heads any place. I tried searching the forums here and got bup-kiss. I figured the FRPP catalog would have it, but it doesn't. Anyone know it?

The head description/specs are in FRPP's catalog or website. The flow numbers are floating around out there.

Everything BUT the combustion chamber cc is in the 2004 catalog. I checked the online catalog.

All the Y's are 64cc; the X has options of 58 or 64.

When I got home last night I pulled out my FRPP catalog and looked through it again. Inthe Pickup truck section they ahd the Y303's listed again and it did say the CC there. 64cc which we have already determined.

Thanks for the info guys.
