Slapping noise when accelerating

    Ok...you folks go easy on me...I am a Harley rider ('03 Screamin Eagle Deuce) and just purchased an 05 V Star 1100 Classic for a daily commuter. Very nice scoot! Smooth and fun to ride. I changed out the oil (what were those engineers thinkin?) and put new pads on the front disc brakes. Going to tackle the tune up / valve adjust next.
    HOWEVER, I have noticed a "slapping" sound around the front exhaust area, especially when I twist the wick. Thought it might be an exhaust leak but replaced the manifold gasket with the oil change. Is it possibly just the intake starving for more air?? Any thoughts out there or similiar experience and fix would be greatly appreciated by this "metric cruiser newbie".

    Stupid question, but is it a key chain or something? I know the key chain on mine flies all over the place as I ride.

    I'm assuming you had to remove the front pipe to get to the filter. It sounds like you may have an exhaust leak where the head pipe meets the muffler.

    I am seconding this idea..... Took me forever to figure this out. Seems elementary but whatever...

    yeh we agree what were they thinkin lol
    have a look at the ORK if ya gunna keep it as its a easy job with one fitted for the oil change
    id say the gasket needs replacin from the sound of it

    One of the guys at my friendly neighborhood bike shop warned me that, when removing the pipes for the oil change, to be sure to seat the front pipe gasket properly or it would give you problems...don't recall what kind of problem, but that could be one of them...

    Since you already replaced the exhaust gasket, I'd try re-torquing the nuts. It is a little difficult to get the torque wrench on those flange nuts. The sound you are hearing MAY be something mechanical inside the engine - valve tap is somewhat normal on these bikes. If you don't see something loose on the outside, I'd try adjusting the valves because this engine needs a fair amount of regular maintenance.

    Speaking of the engine, the V-Star 1100 engine dates back to the eighties when it was developed for a different bike (the Virago). That bike had a different frame and exhaust design and there was easy access to the oil filter. Such as it is, this engine is otherwise very easy to wrench on and it is very reliable - if a bit noisy. A set of pipes will drown out most of the ruckus.

    If you plan on using this bike regularly (as I would expect for a daily rider), you may want to look at an ORK (Oil-filter Relocation Kit). There are about a half-dozen styles on the market and they all seem to work well. The ORK allows you to use regular spin-on filters that sit out in front of the motor (where you can get at them easily). The one I have (Phat Performance) actually uses the 63796 Harley oil filter, so it is real easy to get them at a moment's notice. Also, it gets me into the Harley shop once in a while where, someday, I AM going to get me some American Iron!

    I agree about the valve noise. it always drove me nuts until i realized a certain volume of valve noise was necessary. when it gets a little louder its time to check the valve clearance. too quiet, maybe you adjusted them a little too tight. i couldnt tell you off hand which one, but i wanna say that one of my cylinder intake/exhaust valves is louder than the rest. the front? i think its just because of where it is and the sound has the best path to travel to my ear.

    Actually my 1100 Classic is louder than my girlfriends Softail Classic. She's running stock exhaust while I have Roadhouse slipons. She says she can't hear her bike when we ride together.
