    Well guys, today I brought the starter clutches to the hardening company to have the outer rings hardened to 55-60 HRC. There are 98 pieces left as I used 2 for final testing (machining, heat treating, etc. and actually testing on the bike itself). The outer rings will arrive within a week so I'm able to start selling the clutches shortly. Final price $110 + shipping (most countries, e.g. USA, is $10). I can accept Paypal and/or bank transfer. Please order through email argo1974@hot.ee

    Also, I will keep small stock of spares, so in case of problems, all parts (outer rings, sprags and screws) will be separately available.
    Attached two pictures of the product before heat treating the outer rings. 6x M8x1.25 countersunk Torx screws of 10.9 ISO grade.

    Finally, I hold the ready product in my hands. Yesterday, the outer rings arrived tempered/annealed to 58 HRC.
    Actual orders received so far will be shipped out today and/or after receiving Paypal payments.

    Can't wait to install mine.

    I'm sure I speak for anyone who has been dealing with a faulty starter clutch for years.... THANK YOU ARGO!

    Can this mod work on a XS400? 1980 flavor? I own one and the starter clutch is a pain to get the motor started.

    Sorry, I don't read this thread often ... yes, it works on XS400. Also, I have had few clutches reversed and sold to Kawasaki Z750 Twin owners.
