    2005 Chopper - lately when starting I am getting a kind of whine. Now that whine includes a vibration. It starts but does not sound good doing it. Ideas appreciated.

    make sure your starter hasn't worked it's way loose. should be, i think, 2 screws that hold it to the inner primary housing. but, there might also be 1 from the inside of the housing.

    I checked the bolts I could access. the motor mounts were good. Getting to the starter bolts requires removing the final drive pulley case. The one I could get too seemed tight. I am in the process of charging the battery with trickle charger but the battery seems strong. I probably won't pull the primary cover and will wait for Curtis to get back and let him sort it out.

    Oops - it was private. Fixed. Could that be pressure release valves or a battery that is not generating enough amps?

    Sounds like its engaging okay actually no click click click...

    Could be a bad drive clutch in the starter though.

    Might not hurt to pull the primary cover too and check the clutch hub nut and make sure nothing is binding in there

    Thats no a whine - thats a grind - does this only happen when starter is engaged (button pushed?)
    If so- I would look at
    Starter shaft loose? hitting housing?

    Starter itself -does it do it if on bench?

    If not the starter then it might be the clutch hub nut or clutch bearing - allowing the basket to grind on primary housing??

    Just some on my thoughts - but these are based on the noise only occurring when the start button pressed/started engaged

    I actually think what I would do - and everyone has own opinions

    I would take off the primary cover and hit starter and see if you see anything (maybe removing plug wires/plugs so bike doesn't start??

    I would then remove the starter shaft and see if the whine is gone
    - if it is not - then you know its internal to starter

    -If whine is gone with shaft remove then you know the shaft is either hitting something or its the clutch hub nut or bearing allowing the clutch basket to rub - which should be more obvious where noise is coming from at this point anyway.

    Even if hub nut is loose - you may want to consider changing the bearing and cleaning up the drag marks in the primary housing.

    But other opinions on my opinion are welcomed

    You will sling oil all over the place unless you somehow cover it...ask me how I know. Second thought, dont! ha

    On your second point of removing the shaft how you gonna do that an start bike? LOL

    Regardless I am with you, not sure its necessary the start.

    Yes, it slung oil all over. Even after I dried the bottom of the primary. However the whine was gone. So, I need to find out if the primary case was already like this from previous breakage or if this is new. I suspect it is new wear. If so, and everything seems tight, why would the clutch assembly have moved forward. I did not find any metal shavings in the primary. The clutch seems to still work, at least it moves in and out. Also the bolts done seem worn.

    There is a shim kit I believe that prevents this if it happens I'll post the part number for you if I find it in my paperwork

    I am confused. If this is a new condition then something moved. How is a shim going to help? I am asking not questioning the recommendation. Thanks

    That I cannot answer according to my paper work mine was installed at 3,573 miles in 2009 and now it only has 4,735 miles on it so your guess is as good as mine as to why hope this helps

    The primary chain does not move when I pull in clutch. The clutch assembly seems very tight. I don't have the tool to remove the spring clamp on the outer bearing to get to the clutch nut.
