    Prop pitch on fully built FZR

    Totally rebuilt new short block with new Carrillo racing rods and pistons, titanium valve retainers, Riva cylinder head and main bolts, Riva stage 3 kit . I was running an R&D R3 flash at 8750 RPM, After up grades R&D reflashed to R4 at 8800, pushing 16psi on my R&D upgraded supercharger shaft. Heres my problem: Im running a Skat swirl pitched at 15/23,, I gpsd last night at 79.6 mph, at that speed it was continuing to bounce off the rev limit. Ski seems to have A lot more to give and looking for advice on prop pitch or any other ideas to get this pushing closer to 90 mph. I feel like Ive added almost every option available for this 2009 FZR to really rip it up, upgraded clutch was just installed in April.

    See my sig, you look to be fairly slow at a much higher RPM. Which wheel are you running in there? If I pitched my prop down more I'd be faster than my current speed at a higher RPM but I wanted to keep it safe without touching the internals. With your internals you should be able to run a lot faster and safer.

    I’m currently running a Riva E2 at 16psi. This thing rips hard down low and tops out very quickly bouncing off the rev, thinking a better pitch would put me a lot faster and keep me off the rev. I see you are turning a 14/24,, i have a feeling with my revs topping out quickly I’ll need something a little more aggressive. I’m sure someone has had a similar set up that can advise, I’d like to only buy a new prop once, and be where it should be
