    Cool gpr mods

    I have had my 04 gp1300r just over two years now and have done a few mods to it over the past year as i got a bit bored.

    parts for better performance i have installed are:
    pump tunnel reinforcement (not for the performance but to handle it)
    pump cone
    riva efi
    r&d power plenium
    riva sponsons
    r&d trim tabs
    riva ride plate
    riva intake grate
    riva pump seal kit
    solas 13-19 (was told i should have went for a different one but not which one that i should have went for) any ideas??

    parts for looks:
    rius seat cover
    hydroturf mats
    caution stickers removed

    parts i have bought or have and havent installed are:
    chrome handle bars (dont know who made them)+ odi grips and riva pad
    steering hole cover
    r&d drop nozzle
    gas cap

    I think this is everything i have done but not sure as i think i have missed something!!

    What else can i do to the ski to give me better performance and looks?

    Thanks for any suggestions.

    Whats your EFI settings? Without any engine mods to speak of,that controller is robbing some power,adding too much fuel.

    What kind of performance are you looking for? most of the handling mods you have listed actually rob speed, they help with handling in the rough. And the pump cone makes a good paper weight. one of those items tried several years back and proved not to help, even though some marketing guy's think different.

    I dont actually know what my efi settings are at the minute but any time i try to change them it sets off the engine overheat sensor.
    I want to get a better holeshot and better top end without loosing handling as i use the ski alot in rough water also.
    Things that i was thinking about getting done to the ski are:
    Jetworks
    reeds and keyway
    what else could i get done??
