    Ran the riva with my 55# injectors today

    Nice day, crappy water!

    1- Anyway, my a/f at 8400 rpms was 11.9. Is this to rich? or is it just right?
    2- My oil was to high and it was blowing out of the oil catch can and into my hull. Very messy. At least I hope my oil level was the reason.
    3- Is 8400 the "right" number? or should I be looking for 8500+?
    4- I had to add 2mm to my 3 blade 15/19 in order to get the RPM's off the limiter with an 81.5 ring. Any suggestions?
    5- Water sucked! 3 - 4 bars of fuel, and best run of 78. This sucks, any suggestions.

    Is this with a B-kit or rude charger?

    I think oil out the catch can is due to the oil level being to high, but
    you will have more in the can with a Bigger charger.

    81mm ring and 8500 with flashes or 8550.

    11.9 is perfect at WOT and is what i shoot for when mapping out my EMS system.

    Don't pitch your prop until you get your oil level right. You would be surprised at how many RPM's the oil level will take away.

    Your target RPM's is 8500 with flashes of 8550 with an 81 mm ring.

    What numbers are you getting at different rpm's?
    11.7-12.3 is usualy ideal for WOT. Are you riding in fresh or salt water?
    How do you like the 55 injectors at 1800-3500 rps ?
