I found that there wasn't really more then 1mm difference in any of the openings. The center support is a little wider and extends further on the trx valve. The reed petal mounting is all the same. I don't see any reason why with a little bit of work the trx valve won't flow as good as the cr without having the fitment issues. I can go back through and label which one is which if it's too hard to tell. Let me know if you want to see any more pictures of the trx valve because my plan is to start carving away at it soon. I'm still curious if there is any differences between the 02 and 02B valves. I'm gonna guess that the 02B is a newer version of the 02 and the 04A is an updated version of the 04.
