    Acceleration problem with turbo?

    Hi everyone. I took my 84-hour F-15x out for the second time last weekend after having it serviced for the spring and I've noticed a few issues both times I've taken it out.

    First off, sometimes when I go to accelerate from idle speed and gun the throttle, the ski only tops off at about 45 mph and 5000 rpm for sometimes more than 10 seconds before it finally boosts up into the 60s range. It's strange because it only seems to do this for the first 30 minutes or so I ride. I've also had it drop down from the 60s to about 45 when I was going full throttle.

    Also, I've noticed that when going idle speed the engine sound and vibration seems to have a very slight sporadic sputtering to it (I apologize for the alliteration).

    I am definitely not an expert but my thoughts were that it might be something with the turbo. I am religious about spraying my turbo down after every ride.

    Any ideas?

    Could be a few things. New spark plugs, waste gate soilnoid and dirty injectors or sticky waste gate actuator.

    Thanks for the reply. How can I check if the waste gate actuator is sticking?

    I have just seen that you have a F15X. Not sure on them machines. I have the F12x. If the actuator is sticky it will be hard to move. I would use vice grips and try to move it up and down to see if it moves easy. I think its the wastegate soilnoid. There is guys on here with Honda's that have way more knowledge than me. They comment very soon

    I had it checked out and it was just a bad spark plug. Thanks for your help, it's running fine again.
