    need a lil help with Fercho's jetworks mod

    Hey everyone,

    I own 2 2006 GP1300R's that I bought a few mods for BOTH machines...
    -3 degree keyway
    -cat bypass
    -cat bypass sensors
    -modded r+d ride plate version 4 from Carl at Island
    -spark plug indexing kit
    -r+d intake grate
    -VF3 reeds
    -r+d power plenum
    -riva heads with girdle
    -dynafly impellers (will be modded as soon as I get rpm reading with setback mod from Island racing)
    -iridium spark plugs
    -jetworks mod
    -Riva EFI control unit

    I currently have NONE of the mods in...I used a ride plate by Jim last season which worked out well...but it got a lil ding in it from a moron grounding the ski that had the plate out.

    I need the best Tach out there...is that a Pet tach 2500? Does anyone here sell them?

    Mostly I need help with the Jetworks mod as the title suggests. I am willing to pay anyone who can provide high res pics etc via Paypal so I can perform the mod without losing RPM's (Fercho style). Been working a lot on hull trueing with my trusty 600 to 1200 grit. Anyone who can help me out PM me or email me at [email protected].

    Thanks,

    Mike

    Nice list of mods. You should be happy

    The online store here sells both Pet 2500 and 2100 tachs. The 2500 is the Cadillac, but may be more than needed for recreational riding. The 2100 is just fine IMO.

    Use the search key to find plenty of threads about the jetworks mods, as well as all the other mods you listed

    Out of the mods I have should there be anything else that I add? I am getting the carbon fiber from a friend who owns a local marina to support my pump. Plastic pump rings? new gaskets for exhaust when I do the bypass? Is there any better tach's available than the PET 2500? I technically should only need 1 and I'll swap them from machine to machine to gather RPM data before I send my dynaflys to Carl to have them de-re-pitched and setback.

    At the end of the season I plan to have the motors pulled, crated and shipped to whoever you guys say is the best for porting and giving me a 1490cc motor.

    Thanks again,

    Mike

    If I understand what I have read on this site correctly, you will most likely have to convert to carbs to go 1490. I think the biggest you can go EFI is 1390...

    You dont need to pay anyone just for pics of the install. We are here to help answer most any question you may have. Im not with my ski right now but can take more pics if needed. Where are you located?

    Yea for now I think 1390 is about all you can do on an EFI setup. Don't worry though, ECU's are in the works.... slow works.... but works non the less.

    Disregard this statement.

    NOTE if installing on a GPR 1300 you must use a
    fuel injection controller to adjust air fuel mixture
