Are these any good I was thinking of buying one for my 250r. Does it help the botom end alot?

250R wiseco 40 over DG nerfs FMF fatty pipe and PCII

 

My experience with FMF reeds is that while they perform well, they are weak and don't last. I run Boyesen now.
Yeah, they help the bottom end. I have heard/read/been told that a reed spacer will also help the bottom end but I don't have one on my R so I can't tell you for sure.

 

The whole setup doesnt last or just the reeds?

 

The reeds themselves breakdown pretty quickly. In less than 1 year, the cage insert came apart.

 

How did it come apart?
Would you recommend them when they were good because I think i will try them, I could always change the reeds to better ones.

 

Use boyeson dual stage reeds and a reed spacer. This works better and cheaper.
