I'm betting the side without the curved reed stop was the one that was broken ?
both sides should have stops, but will run like it is, and does not matter which way you put it in
looks like a mix match one side curved one side flat?
maybe back in yz490 days lol i dont know to tell you the truth look at a parts diagram for that engine/year/i would think they would be the same and not mixed matched research it i guess
the curved stops make the reeds not flutter at high rpm...some say it will even stall at high rpms with the flat stoppers/others say they notice a power increase....i would stick with curved and look for power elsewhere....
What type of reed cage and reeds do i have. Cause i bought the wrong type. I want to put vorce three or four in it. But i dont know what im looking for cage wize or reed wise. Dont know if i have to chance cages or use the one i have. Can you help me
