    2000 r6 power loss

    I have 2000 r6 that I recently purchased a few weeks ago , I took it for a ride up to FairPlay co and the bike started bogging down . I got the bike home to find the air filter was really dirty . So I replaced it and still I had the same problem . Any way here's what I've done.
    Replaced the air filter
    Installed new plugs
    New Oli n filter
    Cleaned the carbs off the bike
    Cleaned the jets out they are stock
    Adjusted the floats


    So the bike runs ok , slight idle roughness but I'm getting no top end speed my bike will only go like 75-80mi an hour and not pull any higher after 8000rpm any sugestions ? The bike originally from Iowa . Please help and thank you

    Jetting? Needle adjustment? It sounds like a carb issue to me.

    I'm guessing that you have a bad spark plug wire or spark plug cap. The electricity for the ignition is arcing to the block before getting to the plug.

    Is there any way to check the plug wires? Or is it something that needs to be checked with a diag machine?

    Rybo's on the right track. Fuel, compression, spark. You need all 3 to run. Assuming you have the carbs assembled correctly, the next 2 things to check are spark and compression. An easy way to determine which cylinder is down is to let the bike idle far a minute or so, and spray water on the headpipes just outside the head with a spray bottle. the cylinder that's missing will be significantly cooler. If all 4 cylinders are running at idle, check the line that goes from the fuel bowl vents on the carbs to the ram air tubes. If that line is not connected, the bike won't run at speeds that create any significant airbox pressure.
    Thanks, Jim

    You most likely have a bad ignition coil. Disconnect one coil at a time with engine running.
    The one you disconnect which does make engine idle worse is Iculprit. Verify that it is the coil by swapping to another cylinder .

    Have you checked to make sure you don't have a banana stuck in the tailpipe?

    Have you checked your own tailpipe for bananas lately?

    Re: 2000 r6 power loss

    I checked out the coils ,when i pulled off coil on the first cylinder i could hear it spark but it made the bike idle worse, the 2nd 3rd & 4th made the bike idle high , so should i replace the coil on cylinder ?
