Benefits of aftermarket Reeds?

[JH53210]

I have a '90 YZ125 (yeah I know its old) and it's mostly stock except for an FMF Fatty pipe, (stock silencer.) I was wondering if it would be a good idea for me to get aftermarket Boyesen Reeds or Power Reeds, and if there will be any noticable gain in power. Also, will I need to adjust my jetting for aftermarket reeds? Any info is appreciated.

Two stage reeds such as Boyesen help low to mid-range power. A new reed block assy such as the Rad Valve is a bit more of a performance enhancement than just reeds and should give you more mid-range hit.
