Is my Reed Valve damaged? Picture attached

14000 miles on my 2014 STR. Just finished the valve check, all was good there.

When I unbolted 1 of the 2 Reed Valves (closest one to cylinder #1), there was this thin metal plate that looked out of place, sticking up out of the valve cover. I'm not sure if this shifter when I took off the Reed valve cover, but now I don't know where exactly this piece goes.

Prior to the valve check today, I haven't ran the bike in a few months but never had any running issues. Occasionally hot starts were a problem (had to give it some throttle to get it going sometimes).

Anyone know where this plate came from and where it should be? How could it get like that?

Edit: Found this thread but still not sure how to fix this, or what the best route would be.

I went ahead and took the reed valve out of the valve cover. There are two small screws on the back side holding a curved ramp in place. After I took off the ramp piece, there was a clean section there and I was able to line up the loose piece directly on that line and it matched (there's a slight curve).

So I assumed this part was supposed to be sandwiched under the curved ramp. Although, I don't know how this part would have came loose and made it through the square hole to the upper side if this is how it's assembled.

Edit: Having trouble finding this part specific to Triumph, I looked up reed valves in general and understand the design now. I'm more confident now that this is correctly assembled but would appreciate if someone who knows could chime in so I don't have to have that worry in the back of my mind.

Just get some block off plates and remove the reed valves. Though if you want to keep them you can probably find them on eBay or contact someone on eBay selling Triumph parts and get one from them.
