Riding to work this morning slowed down at lights and something didn't feel right, pulled over and did a check of bike and found that all 5 bolts holding rear sprocket were loose,no big drama tightened them up and on my way. Now will pull out back wheel and loctite them, maybe add a chrome cover while its out. As this is my first harley is this a common occurance?

make sure the bolt hole are not out of round or hellicoil them if there's enough room  wall thickness  , allways check on servicing

Isn't this bike brand new???  If it is I would be taking it up with who ever you got it off....

 Thanks racer will check that, it was 2nd hand from dealer sparra, they will be getting a call about it.

Has anyone else had this problem  ???

I've been paranoid about it ever since I replaced the factory zinc bolts for chromies.

Although I did use plenty of loctite,and torqued them to manual specs,in correct sequence..........

Oh,nearly forgot......

Somewhere I read in the manual that says,once these particular bolts have been tensioned once,they recommend replacing them.

Maybe these bolts have been tensioned a few times during a sprocket replacement ??

Put a new pulley/bolts /wheel combo on a while back,  bolts loosened up one actually wound out enuff i heard it touch the frame, re did with locktite no problems since, but i check before i ride every time now

there's no cush drive  on the rear wheel for shock ,  esp on sporty's  but on the big twin's with the weight V torque it's in the middle & something has too give  i allways check every bike that i lean-on ( service)  old shovels were good for that , my old hotted-up cast iron sporty use to rip the sprockets rivets out  & break the spoke's  in the back wheel  it was & issue on that good old bike

Thanks for all the advice guys, have booked it in at dealer to check and fix, was going to do it myself but then thought under warranty may as well get them to fix it. can understand that ozroder about cast alloy wheels as i own a non ferrous foundry and have been in the industry for 30 odd years, have seen a lot of wheels made and fail before they got anywhere near a bike or car and that was with doing everything as it should be done, have to worry about these new alloy wheels people are using that are cut out to look cool, especially if they are manufactured in china or similar as their quality testing is just not up to scratch for most.
