    '03 GP1300R questions (EFI)

    I am currently waiting on a warranty item to be repaired (1rst time). In the mean time, I have purchased (for the '03 1300), the following:

    1) R&D plate
    2) R&D trim tabs
    3) Splash Guard
    4) Race filter
    5) Race filter sock
    6) 45cc heads (cast) and girdle kit (might get rid of)
    7) v-force III stuff
    8- Riva fuel controller
    9) Riva D-plate and chip
    10) Pet 2100dx on the way

    Basically, I will be installing these items as soon as the ski is returned, but I have some questions while I wait....

    1) What would be good start settings for the fuel controller? I do have the instructions, but a head start would be great.
    2) What plug are y'all using for this combo?
    3) I assume 92-93 octane fuel. Is that a correct assumption?
    4) Any other input is appreciated!

    Thanks.

    I would recommend that you get a baseline on your ski before doing any mods.

    Then when you start installing the parts, do one at a time and test it so you know if you are gaining any speed. Try to keep a log on everything you do to help you along the way.

    Just my .02 cents.

    Well, the plan was to wait on the tach, then

    1) Get baseline
    2) Install plate, tweak
    3) install tabs, tweak
    4) install d-plate, chip, race filter, v-force, fuel controller, splash guard (tweak controller)
    5) install heads (tweak controller)
    6) final (hah!) overall tweak.

    I have every gasket that I think I will need (exhaust,head,etc).

    Would you break up #4 individually? If so, how often do you personally reuse gaskets?

    By the way, I saw a small temp, reletive humidity meter at home depot I'm considering getting.

    Any more opinions/answers? Tach not here yet. I've still got some "plan of attack" time. Cheers.

    When are you sending the jugs to Lowell?

    Get your baselines first and see what needs to be adjusted...it will be vital to write down your rpm's/gps numbers when you get the equipment to do so. I do wish you would get those jugs ported, the power is very clean and fast when you open up the port timing. And with efi, you'll have seemless acceleration and it will hard. $500 well worth spent IMO.

    I love riding Flyboys efi ported ski more than mine...it just feels so much better than a carbed ski.

    Make sure you get the Fercho jetworks mod in that list.

    And yes, it would be better to do one or two mods at a time so you can log the changes in order. Just steer clear of any go-slow parts, don't do it.

    "When are you sending the jugs to Lowell? "

    I had planned to do that "after" the other installations (probably after the Fercho/Kerry package also). Is that not a good idea?

    "Just steer clear of any go-slow parts, don't do it."

    Hopefully, I don't have any in my list. Do I??

    Thanks,
    Steve

    The Kerry/Nando handling will deal with the inconsistencies of the trim tabs and rideplate (Go-slow stuff). Since it's winter, I would strongly suggest pulling that pipe, head and jugs, then send the cylinders to Montana to Lowell. Your turn-around will be quick and then when you begin to dial in the efi and the prop bends..you can also put the V-force in in one swipe instead of having to take off everything when you get ported. And don't worry about blowing anything, the port specs will not make you lose 1 hour of reliability, you have my word.

    The difference in ported and non-ported is big..no matter what final top-end numbers being recorded on the board, there is nothing that can get you better hp/quickness numbers than porting. The acceleration is phenomenal. I cannot get enough of the ported efi...it rips.

    I wish everyone on board with an efi would go ported..it just makes the GPR come alive and feel like it's "naturally" supposed to be this way.

    Hey Steve...I would do the engine mods first...
    -pull the pipe-install D plate
    -pull the heads and mark where the power valves are open on the rear wheel
    -install new heads -OH and get rid of the stainless bolt kit...use the stockers-you will need to get 4 new bolts
    did you get a new head gasket?
    pull the intake assy off and slowly, install the cages and re-install throttle body assy-be careful with the fuel line disconnect at tank(plastic)
    -install the filter and sock
    -install controller...be sure to tie wrap the cables so they dont slam around
    -re-install pipe...use a spray bottle with some liquid soap to lube the rubber boots
    -TORQUE everything according to you BIBLE(manual)
    -use loctite,coppercoat and anti-sieze
    -install your tach and tune motor

    Then work on the handling...my .02

    oh and I forgot...you have a air temp sensor in the front you filter assy...dont forget to re-attach it


    Mike...some people dont have the money or time to port a motor. I know you mean well...but there is some truth to the old saying...baby steps

    Once you get a feel for how the ski feels and goes together...then think about porting
