    2000 GP1200R overheating

    Would like to ask for some first time help. I bought this machine new, and have done various mods thru my local Yamaha dealership. Most all Riva stage 11 kit has been installed except the stock heads were just recut. So factory cooling is still intack. I am capable of installing addition cooling lines, but I would like to ask for some help with what to order as far as the thru hull connectors, cooling block, and additional dumps. Some pictures on where to run hoses etc; would really help. Also my first digital CDI Unit burned up, so help finding a reasonable priced replacement would be greatly appreciated. Thanks for help in advance.

    Welcome to the Hulk..

    The factory cooling is fine the way it is. Some dump #3 cylinder to get the pipe hotter.

    My first question is - why do you think you have an overheating problem?

    Overheating-powerloss

    It maynot be overheating; but after 15 min. the power is greatly reduced.

    Can you give more details? You're not giving us much to go on.

    What's the rpm drop after 15 minutes?

    What's the speed loss after 15 minutes?

    Is the pipe and/or heads/cylinders feeling unusually hot?

    Do you actually still have the original catalytic converter in it? By design, the pipe will get real hot, and with time I'm sure that they will plug .

    This could cause you to slow down.
