    Angry 2011 clutch issue teething if you will

    I have a friend with a 09 FZR with 2011 clutch. He told me over the phone that when the last rode the the cluch failed it was also an 09 the only replacement that was availible was the updated 2011 clutch.

    After about 2.5 hours after repair it and they dug into.it again to remove the clutch and upon removal or planetary gear found 7 missing teeth.. a few minuteslapeter the driven clutch gear was tootnotifiely
    much to the amazement of service guys as well as the recently notified faint owner of this. FZR.

    Is it a gear mismatch?

    2011 clutch work too good and not open fast enough?

    Is there an updated gear that goes with new clutches?
    Is Yamaha helping out owners with this issue

    The information I have is that the late 2011 s/c clutches have a softer gear teeth hardening process so they won't brake off the s/c clutch gear, I have no proof on this only information passed along to me by a reliable source. Tommy Jordan

    If I had an endless supply of money.. I sure would like to try and get a 2011 gear cryoed and then test it. Wonder if that would help at all.

    The second version of the clutch is much worse than the original. I first thought it was taking the teeth off the gears because it was so strong that the gears were the next weakest part, however I now have a different opinion.
    The second style of clutch begins to let go after only a few hours. The problem is that unlike the original that just rolls over and is gone, the second version of clutch goes and then grabs. This can go on for several hours. You just feel a slight surge every now and then. If you have a MoTeC you can see it on your file. Therefore I think the slip & grab is what breaks the teeth off the gears.
    I have replaced two new style clutches for old style this week and in both cases the clutches wouldn't turn the charger consistently when at running temp but have been locked in solid when cold. Even in a vice with an R&D tool they cant be slipped yet fail in the hull.
    So I have gone back to the original. If I can get 20 hours from that it's a minor inconvenience compared to the damage the second version of clutch can do.
    The only solution is Turbo but I am looking into oil as well via Rick XP's research.

    sorry to hear about your bad luck with the 2011 clutch.
    is the old style clutch still available in the greenhulk store?
    i know that r&d has had good luck with modding the idler gear and using the billet coupler. they also have a mod to the flywheel.....
    then there is the water cooled supercharger housing that helps keep the temps down. it is to soon to tell if helps with the clutch. but, if it helps keep the oil temp down that is beneficial to the clutch.

    some guys installed the 2011 clutches when they first came out last year. then they started loosing teeth. so they left the 2011 clutch in and parked the skiis in there garage. waiting for a "guarenteed solution" or a affordable turbo kit.
