Sooooo,
Something I know nothing at all about is the reed valves. Nada, zippo, zilch.
I assume my 4K miles scoot has the original ones in it. I’ve seen the intake piece that holds them but I’ve never disturbed it from it’s resting place. How much difference is there between generic stock replacement and a “nice” set from a quality manufacturer? Are reed valves a works/doesn’t work kinda thing?

How much difference is there between generic stock replacement and a “nice” set from a quality manufacturer? Are reed valves a works/doesn’t work kinda thing? Actually, first you want to ask what the actual differences are between stock and aftermarket petals. - Longevity (primairy) - Stiffness (secundairy) You want to change out the stock steel reed petals with carbon fiber or glass fiber ones. Steel can get fatigued and break, possibly damaging your engine. Carbon/glass fiber can also break, but it won't do any damage. Just shut down the engine in the worst case. Tuning stiffness is a factor you will only want to do in a high performance motor, where all other major factors are already looked after for. It's a way of super super fine tuning. My advice, don't bother too much. |

I have found for me there is a slight performance gain. But the biggest improvement was in throttle response. It was much improved.
This was fitting a performance block. Not just changing the petals.

I definitely think there can be More power but only if you have all the other components slowing better such as a large carburetor a high revving high end Cylinder as well as a high revving free flowing pipe, In this case you can definitely get power simply because the case kinda suck in more mixture and basically flow better usually though this will require enlarging the intake port on the block and like mentioned above getting a high quality read cage not just Changing the reeds on a stock cage however I still will do just that in some instances as I notice a better throttle response.

I found the corner of one of my Zuma 50s reed petal had broken. Luckily no visible damage. I replaced with carbon fiber. Back when I was racing my YSR50, one of the tuning tricks
was to spread the reed cage until it barely fit back in the cylinder. Allows the reeds to
open further. It made a noticeable difference. But then we started with about 6 hp
