    Boat 2: 2005 GP1300R
    R&D unmodded rideplate with holes filled, stock trim tabs, 800 grate. Stepped stock sponsons.
    Run 1=72.3mph
    Run 2=72.4mph Small side to side bobble.

    R&D unmodded rideplate with holes filled, R&D trim tabs(trued), 800 grate, Sponsons up.
    Run 1=71.6mph
    Run 2=71.8mph Very bad porpose, almost unrideable.

    I wanted to see what effects the tabs and sponsons had on handling and speed.
    For me stepped stock sponsons are a must, I was amazed how bad the boat handled when they were all the way up and for speed I really cant say how much they slowed me down because the boat porposed to much to get a good run.

    R&D trim tabs (trued) are a must. They do not slow the boat down at all. I actually saw a slight speed increase. They also shin in the ruff water are too.

    Just wanted to share my findings with others.

    All readings were done with a garmin etrex gps.

    The trim tabs have been trued flat. Then went through lots and lots of sanding. I would like to thank my Dad for that. He did all the sanding and I polished the pumps. My Father and I both have 2005's.

    Did you just sand those R&D tabs flat or have they been shortened? Good test.

    Voodoo. The tabs on the table aren't trimmed. Great testing. This kind of testing is a big help to everyone. Do you have some stock metallic tabs you can test too? It would be cool to have a tab shootout.

    Riva uncut

    stock

    R&D uncut

    Riva cut

    R&D cut

    Then test them all with one shim, then two and so on.

    I might do this next time out with

    Riva uncut

    stock

    Then shimmed.

    OR I could send you some Riva uncut and stock shims and you could do the fullblown test????

    Let me know.

    This is good stuff!!!
