    Recipe 4 stock bore 80mph GP1300r

    So i have been thinking about building a GP1300R. I currently have an ultra 150, 15f, and rxp. I have been seeing a couple of 80++ mph stock bore EFI skis on here. I am just wondering what mods need to be done to get to 80 or high 70s.

    Things i am looking for:

    somewhat reliable
    EFI machine
    stock bore
    single pipe

    I have heard a good plate on a stocker will get you 5mph??

    thanks for the info ahead of time!

    5 mph on a stock boat with just a ride plate is a tall order to fill...

    Lots of different recipies on 80+ 1300cc boats. IMO you will have to pick a tuner and go with him to get there.

    5 mph on a stock boat with just a ride plate

    I dont know about that but 2-4 mph sounds more like it 4 being a severe gain and many hours of adjusting....
