Hi All,

hope someone can help me with this, I have a 1997 916, for some time ive had some starting problems, ie clicking to start with which I sorted (poor connections) Now im getting something worse, Im thinking its got to do with the dreaded sprag clutch, and something more, I will try best to describe what is happening

On a cold day or after a long period of standing the starter will intermitantly just spin without engageing, sometimes after engageing, the bike will spin over but not fire a clanking noise will appear as if the starter was missengaging, it sounds awful, once this happens i stop trying to start it , give it a second or two then try again, after 3,4,5,6,7, attempts it will finally engage enough to fire up the bike, once its warmed up its not as difficult to start again, but it is getting gradually worse (and more embarrasing) your thoughts would really be appreciated

PS ive searched the boards already, found simular, but not the same as im experiencing

Thanks

You've definitely got a problem with the starter sprag clutch.
If it chatters the eccentric rollers damage their bearing surface, and get worse. Always.
I had 2 go on my first 916 before I found out the fault was the battery terminal connections causing too bad a connection to reliably drive the starter, which makes it turn slowly and off you go into chatter land.
If its spinning up without engaging it means that the eccentric rollers are getting stuck and not clutching their bearing surface.
Either way means a strip of the left side to remove the alternator and see what condition the starter clutch is in hidden behind the alternator (and if thats on the cards, it means the other nasty, the altenator nut gets checked at the same time anyway )
