Rpm and top speed loss after changing reeds?

[1224bret]

Last year I installed a set of ccms fiber reed valves and had my injectors professionally cleaned all went back together and the motor runs great but I've lost 400 rpm after the change. Ran it last year thinking maybe the reeds needed to break in but nothing has changed. Before changing the reeds I was running 5600-5800 rpm now I'm around 5100-5200. The 250 in my signs the engine and the specs are 5000-5800 but I'd rather be on the upper end at least that's what I think would be better. Anyone else ever have a similar experience after changing reeds? Is 51-5200 rpm ok or should I re-prop? Running a 23 pitch mirage right now no issue with hole shot or any other issues. Ideas? Thanks
