Whats the symptoms of a failing sprag clutch ? My mate ( he's not a member of RSV zone!) has a 1999 millie (38000 miles) which some times "jams" on starting and will only go if he rocks the bike in gear when it does ( quite often there is a clunking noise as well), also the starter just spins some times(sounds like a drill running) It will also only start if the battery has a full charge if its a volt or so down it wont start! He has had a rectifier problem , the brown connector had shorted out I have sorted that for him (bridged the wires) and his battery is now charging ok. I think his sprag cluch is on the way out proberly because of the low battery voltage caused by the faulty brown connector ( his bike has for a while been starting ok after being on trickle charge ,but been a pain to start after a ride) Am I on the right track? does that sound like a fooked sprag?
 
Spinning starter with no/slow engagement to motor, clanking or noises from the flywheel area are all sprag symptoms.

His battery issue probably killed it off but at 38k it was probably getting tired anyway
 
Cheers Spoonz! unfortunetely it looks like he got a bit of a repair bill comming!
