Thread: Loss of power?

  1. #1

    Loss of power?

    I have a 08 ultra250 and lately if I gun it from an idle it losses power at mid throttle. Any ideas why?

    How do you know plugs are perfect ? You can not visually tell there good. Replace them with new ones. The you'll know there good

    I took it for a test run the other day for the first time since it was in the shop at the end of last season. I had the exhaust gasket replaced. And while they replaced it they checked the belt and compression. All perfect. I've only got 80 hours on it and about 80% of those hours are doing less than 20mph pulling my wife on a tube

    Plugs were replaced when I put it up for the winter. Less than 30 mins on them. But I will check them regardless.

    Slow riding kills plugs.

    True. It feels like the air fuel mixture is off. If that's possible. Does it have a air filter?

    As sir b pointed out above check your air horn it's on the air box by the gas tank make sure it's not stuck against the hull. If the sc is good belt is good air horn is not against hull. Most likely cause is plugs. You are using the orange key correct ? There is no air filter. Change your plugs and go from there.

    Lol. Thanks. I'll get the plugs but I want one more ride before changing them. Last year every time I changed the plugs I would get water in the oil and have to change the plugs again so I want to make sure everything is perfect before I go wasting another 80 bucks
