    I know it is a known issue with racers. Not wanting to start a pissing match just want to get a feel for who on this forum experienced it and when. Keep it nice. Thanks.

    - If you posted you did have failures please post what type of riding and how many miles.

    Both 449 and 511....511 raced offroad 2 seasons with oil change between every race....no problems with either one
    Add Zip-Ty vent to the 511 after 1st year, increased oil to 1150.

    While we did some racing, I would classify our use as moderate and low hours (neither bike did more than 30 hours while I had them and we were racing 50 Expert in 90-120 minute GPs and XCs mostly). Little sustained high rpm riding and also little muddy hillclimbing type stuff.

    How (apart from a total breakdown or metal in an oil change) would you know if you had an issue?

    Starts slipping then blows up.

    I have seen a picture from Tinken with a box full of them. I know it is a known issue. I think the ZipTy oil kit is a great idea and probably eliminates a ton of these from ever happening. I just wanted a feel for those who have had this issue and the specifics. Mainly for my own info and concerns of possible future failures and trying to avoid them as i love this bike and wish to keep it long run. Heck it has already outstayed most bikes around here.

    The only way we can test is take it out and put it on our fixture. We then use a torque wrench to measure the clutch pressure in Ftlbs. I took mine out and measured 242ftlbs. @150ftlbs, we replace the limiter. If you feel any clutch slip at all, try to have a TL on hand.

    What will we see for symptoms? sounds? Feeling like the clutch is slipping? Any clue before it lets go?

    If you notice it, it will feel like the clutch is slipping. Customers have complained about it in the turns and under hard acceleration. Seems to effect the SMR riders more.

    Makes sense....dirt provides slippage/torque reduction that pavement doesnt....maybe if they didnt have CTS helping them stay hooked up then the torque limiter would live longer !! :confused:

    No problems with mine (2011 TE511). I ride mine in the woods and occasionally play on an mx track. It rarely sees highway use, but I have raced several hare scrambles with it.

    This really makes me cringe when I think about how hard I push my bike on the Tar.
    Race starts the other day I felt like my clutch was slipping but it could have been me modulating?
    I haven't noticed it on the gas out of corners yet. I'm hoping a slipper clutch will further reduce stress on the TL.

    If it's any consolation, I have designed a new torque limiter which will not fail and transmits horsepower with the efficiency of zero loss. Currently prohibitively expensive, but if bikes start exploding, I will green light manufacturing.

    Thanks for the info and video. No issues so far on 6600 miles on my standard SMR511.
    I presume the off throttle whine on the video is not related and is just due to straight cut gear on the clutch (mine does this)

    Well I think it is time. I believe my TL is slipping. 6000 hard miles. Bike makes about 2x the power it did new so expected. Not a big deal. replace and ride. Just reporting.

    Pm me with a price on your Beefed up TL Tinken.

    If we were to swap gear boxes with a TC no TL is needed right? Can they be swapped easily enough?
