For Yamaha 62T or 64X. The reeds look to be in pretty good shape, but I have no idea how many hours they have on them. I also have a pair of carbon cages that are sort of a RAD valve copy and use the RAD valve reeds. The reeds are on these are shot. $50 for both shipped CONUS. Thanks for looking.

I just did a back to back test on these RAD valves with new Boyesen three stage reeds (can't use the extra reed stop raiser plates on stock manifolds, the cages won't sit into the intake tract) and Boyesen dual stage replacement 760 reeds to the OEM ones on my modded 701, these RAD valves definitely make a difference even without the extra raiser plates between the cages and reed stops. When I went to the stock cages and stock replacement reeds mentioned above, there was a rather noticeable reduction in power and rev out. Definitely a higher flowing reed and cage design here, holeshot power was noticeably improved too :)
