    I've been seeing these auto clutches on eBay for some time now and I know these are made in Taiwan, but I've been wondering if anyone out there has bought one of these and how it's been working out for them? I've searched many times for info on clutches on this site and mostly come up with stuff from 2008.
    I'd really like to hear about anyone's experience with one of these, as I'm sure someone out there must have bought one. Like to hear from you.

    Looks like there are 3 different clutch arms Chris,(see pics ) 3 different pulleys too. 50mm,70mm and the 90mm. then there's Quenton clutch, and also the 3rd millennium, now add 2 more clutch arms, A lot of this stuff has to do with installation, Qunetons clutch should be a good one, with the different sizes pulleys.
    I know jb has been happy with his.

    My Buddy Bob has the clutch your showing, works good. It's on a wc-1 (1999)
    He lives in the Whittier Hills by me, and does some peddling. He went with the 90mm ,I think he could have gone with the 70mm, but again it does the job.

    Thanks Ray, What's the 50-70-90 mm measurement for and how is each size different? The reason I'm looking at this clutch is price. I'm not looking to pay more for the clutch then I did for the whole bike. $300 is what I paid for the bike. I already sent the cylinder and head to Quenton for some work and along with the new carb it's running good. I'm hoping to get the carb tuned in a little better as I'd like to be able to hit at least 40 mph.
    I'm also working on a few exciting upgrades that I hope to have done pretty soon, so keep a eye out for them on my Old WC1 Cruzzer Project build thread.

    Hi Chris, the manual slip clutch is a 90mm pulley, the pulley that goes to the back sheave. The auto clutch comes in that size or two sizes smaller, the 70mm or the 50mm the two most popular are the 90mm and 70mm.
    Here's a pic of the manual slip clutch and the auto clutch that are both 90mm pulleys.

    Looking forward to seeing your upgrades too.
