It's no secret that batavus m48 are ultra low compression engines. Unless you are decked and using a high comp head or kit, these reeds are a little too thick and they'll struggle. Like others have said, cut the wings off. If you want the most out of these, cut new reeds with the yellow polini .25mm Reed paper, and don't even THINK about putting these on an m48 unless you have a 30mph pipe or an aftermarket pipe, it won't be able to breath and the added flow goes to waste.

The below post pretty much sums it up, cut off the wings except for the part where the bracket holds the petals on. Use blue loctite on the little threads to help hold them. Helps my batavus get more fuel to accelerate and actually have life.

Made my bike accelerate like a mf'er. the reed block is insanely high quality. The carbon reeds flap-like hummingbird wings. The only issue is that those metal flappy things are too big to fit inside the engine. With them on, the reeds wouldn't move once it was placed in the engine. I had to cut them down to just be a small mounting bracket. After I did that they worked better than I expected. My bike accelerates much faster. Top speed is a little better. Main thing is these boys make my bike loud af. Sounds like a dirt bike when you're hitting 30. Don't know if that's a good thing yet, we will see what my neighbors say....
