Reed Valves on GP292

[GP292Racer]

Could anyone tell me what year yamaha put a reed valve setup on the GP292? I believe the sno jets had it on the 74 sst 295 with the yamaha engine.

I believe it was '74 - '76. I am looking for a reed 292 cylinder for a backup motor

I would like to find one for my mod motor with my sr pipe
Last time I ran with my pipe, I ran it on my stock sled and popped a piston!

I have a GYT kit tune pipe that I am not using anylonger. It is not for sale, but if you want, I could measure it up and provide the specs. PM me and perhaps we could work something out
