Heres a Video on the Milwaukee 8 M8 Harley Davidson BDL CS-34A Compensator sprocket upgrade
Harley Davidson M8 compensators even screaming eagle ones will break if bike is modified and with time ! the metal is WAY too thin see pics if running a upgraded or even stock motor this is a big very expensive problem as you can see - if your clutch is damaged when it goes we highly recommend the Barnett billet upgrade call Mike 01773835666 if any queries.
