2002-2008 CRF450R baseline flow numbers

[pcnsd]

I have a 2008 Honda 450 on my bench to review and perhaps modify. This head has been touched by another. The carb to head transition has been extended and smoothed. The bowls appear to have the same treatment. All in all, it is likely some company's "Stage 1 or 2 porting" that you see advertised. Does anyone have baseline numbers they would be willing to share? I don't think this is going to be far from stock but would like to have comparative numbers if possible.

Thanks for your consideration.
