    so i perused the index and didnt see this covered. metal on metal, almost grinding or rubbing sounds from the clutch area when the clutch is engaged, but when i pull the clutch it goes away. its an 03 adv, but i dont think it has anything to do with the hydro clutch itself. sounds like something loose with the basket maybe? before i pull the cover are there any thoughts?
    thanks in advance

    p.s. if theres interest i will take pics and make a right-up for the index.

    That is correct. $10. ($5 plus... a $5 "harshin' my 'tude" fee)

    You are the 199th person to comment on the "noise" an '03 and later LC4 clutch makes when engaged and in neutral. At some point, we all thought something just "had to be wrong". Many thousands of combined miles later... no issues.

    To bad you weren't the 200th... you would have won a new KaleCo flux capacitor, valued at $175,000.00.
    Bummer huh? :dunno

    Tis normal for the beast.

    Think of it like a Ducati clutch they sound like a toll box full of spanners rattling round inside.

    As a Duc owner would say "Its just character" or "It wouldn't be a Duc without it"

    PS I am not implying that the 640 is on par with a Duc (the 640 is quieter) - but they have a similar design philosophy in that performance is paramount, niceties only exist if it doesn't affect performance.

    My adv clutch sounded like it had bits of metal rattling around inside it too. Only in my case it was because it did have bit's of metal rattling around inside it.

    Busted rivets, doubt that you have the same problem. :D

    Clutch noise is commom for this model, but if you have excessive noise from that side of the engine, you may want to look into it.

    We had an 03 Adv come into the shop and the customer had the same complaint. We almost shrugged it off until we heard it. The noise was excessive. We pulled the sidecover (very easy by the way) and found that the three allen head bolts holding the counter balancer to the gear, had sheared. Luckily, there was no damage to the engine case, but the counter balancer, gear, and clutch cover had to be replaced.

    Here is the official bulletin:

    Man... I forgot all about that one. It's so rare to hear about one that actually loosened up.

    Meat should put that TSB in the Index.

    Good reminder Dirtyboy. :thumb

    OH OH OH HO, PICK ME PICK ME!!! My new 2004 SMC's clutch sounds like a roots blower, its kinda cool.

    Hey Creeper, if I call you a lot of bad names and kick dirt on you, will you charge me the standard"harshin' my 'tude" fee"? If so, will you just deduct it from the $175K I won from you, you can send me my money western union to my brooker who happens to be in Nigeria this week?

    Love ya like a brother:evil

    Blower? I'm sorry, you have the wrong number. All "blower" inquiries should be directed to this department.

    The noise on my 2000 changes only slightly between clutch in/out, about like all my other bikes. Did they change something on later models that made them noisier or is it luck of the draw?

    That makes you one strange voyeur... nah, scratch that; it's circular logic.
    Bookmarked for da index.


    Funny, but I never hear any noises from my LC4 :dunno
    Kinda sounds like a turbine under moderate load.
    (note: in order to replicate my experience, please remove your skidplate - it reflects and amplifies the noises coming from that poor austrian hamster bustin' his balls in there!)
