    FZR Riva Stage 1 kit installed and now going slower! Help

    Thanks in advance for any tips,guidance with this issue.

    Running a New 2009 Yamaha FZR and gps'd 65.6 mph stock out of the box and I have now installed the Riva Stage 1 Kit and bike seems to have a slower smoother take off and
    only gps'd 65.2 top speed. I have checked over everything over and over and cannot see anywhere that I could have made a mistake during installs. Does anyone have any idea, suggestions or tips as to why I have wound up with a performance loss after installing kit?
    Here is a list of parts installed
    -RIVA Solas R Series DynaFly Impeller, 13/22
    -RIVA Performance Power Filter Kit
    -RIVA Intake Manifold Uprade Kit
    -RIVA Free Flow Exhaust Kit
    -RIVA Pump Seal Kit
    -RIVA Top-Loader Intake Grate
    -RIVA Performance Ride Plate

    What are your rpms? Knowing your rpms is way more important than your speed. That setup with the right prop should be 71+ all day. I recommend buying a tiny tach commercial version to check your rpms

    I can't remember now. I will find out what the rpm's have been in the morning. Thanks. Great idea a tiny tac would be nice. More reliable for sure

    i had exactly the same when i did mine. its the prop, remove it and fit a skat. the difference is amazing. i went with a 13/23 if you going to do any more mods that is the best one to fit. the solas just doesnt work on a stage 1.

    I run a 13/20 skat. Perfect prop for your setup IMO.

    Wouldn't you think RIVA would sell a different prop as a package deal???
    That's weird to me bc I'm sure that kit states the performance gains, hon?

    I have the solas 13/22r as well and it sucks for me as well. I can't get over 7500 rpms with it and cavitation is bad.

    Randy. first of all your stock speed is slow.
    If my FZ went that slow out of the box I would have taken it back and told the dealer to figure it out. Secondly, I would ditch the Riva intake grate and go with the R&D intake grate for safety; and I would try the VX ride plate vs. the Riva plate. The intake grate and ride plate setup are very critical on these skis. Based on what I have seen on this forum for the last couple of years, some of the Riva parts do not provide the biggest bang for your buck on the FZ models; just my opinion.

    Thanks guys I really apreciate all the feedback. I have been reading alot of complaints with the prop used in the Stage 1 kit also. Kinda confused on why they would sell it in the kit and give performance claims while most don't seem to be seeing it. We do have alot more changes planned for this bike so it looks like I may need to look into a different prop here. The end goal is 85 mph and a hold on for dear life take off...
