One thing not mentioned so far is belt tension. If the bike has been worked in the past by a HD dealer for recalls they will have set the belt far too tight. And that could be what caused the pulley spline wear if it wasn't rectified. Ages ago, my M2 had recalls done at the old Chester HD shop and they set the belt tension like a bow string. I loosened it as soon as I realised. While you're at it, check rear wheel bearings for wear too.

Your neutral switch has done you a massive failure by failing.... and thereby allowing you to discover this worn pulley whilst you're in the comfort of your workshop.

I read about that a decade ago and have ensured that its not overly tight. Good call on the rear wheel bearings too thanks.

You have no idea how delighted I am to discover it before it became a roadside epic and garage cursefest!

The big nut came off this morniing without any drama - seems not to have been fully tightened. There was loctite on it and the locking plate screws too, but not tightened sufficiently.

As far as I can see the output shaft splines are not damaged much (if at all) but the sprocket is toast and very chewed up. I'm guessing the sprocket material is softer than the output shaft.

What's your experienced opinion of the output shaft teeth, pics enclosed?

The shaft splines are deliberately harder than the sprocket. For reasons you are now fully aware of! LOL.

As we speak all over buell-land those buellers who've read this thread are pulling off sprocket covers and checking tightness...!

Splines in the pulley look OK in your photo ?.....if you do need a new one Twin Motorcycles are your best bet, they make their own and are far superior and cheaper than OEM.
.....and where's your lube plug ? :o

That'll be about 2 or 3 people then.

When Maz asks you about your lube plug, Jocklandjohn, on this occasion he's not being a sexual deviant :oooops: A search through the forum will yield loads of info but this is probably a good starting point for you - http://www.ukbeg.com/forum/viewtopic.php?f=17&t=742

The pulley is wobbling about good style, seems well worn internally. The splines are apparently ok - the spacer ring which goes behind the sprocket is snug all the way out to the front of the output shaft which suggests minimal spline wear.

I am so pleased someone lower down has explained your closing remark - for a moment I thought it was a Brokebike Mountain moment! :-)

Obtainable from...?
