RTme2 Posted April 20, 2006 Share Posted April 20, 2006 Some claim that you can smell a clutch burning just before it goes out. On an 11RT, I can't imagine that you could smell it...too low and away from the rider. Besides, it's not vented. Right? Link to comment
RickP Posted April 20, 2006 Share Posted April 20, 2006 Mine died (along with the input splines) on a Saturday. The previous Thursday I rolled into the dealers service lane for a 6K and the service writer said "What's that smell?" I said "Yea, you need to look at that." The last couple weeks I could also feel heat on my right calf when stopped and feet down. Do I sound bitter? Link to comment
matanuska Posted April 20, 2006 Share Posted April 20, 2006 Oh yea, I smelled my clutch plenty when I was first learning to ride my R850 (once stopped of course)! Yes, it is vented - the hole for inpecting the TDC mark on the flywheel (though that one usually has a rubber plug) and the hole used to insert a tool to lock the flywheel at TDC during maintenance. Also, the mating surface between the transmission and engine housings doesn't have a gasket so stink could conceivably seep out of there too. I know oil will if you have a leaky rear crankshaft engine seal! Link to comment
Joe Frickin' Friday Posted April 20, 2006 Share Posted April 20, 2006 It's plenty vented. Big gaping clearances around where the starter meshes with it. And I've smelled clutch plenty on abusive launches before (high revs + lots of throttle once you start engaging the clutch). As to smelling it just before it goes out, I don't have personal experience with this, but I wouldn't doubt it; the first time it would slip would be under high-torque conditions, which is going to rapidly dump a lot of power into the friction plate and cook up some righteous stink for ya.

Having just replaced a worn-out clutch I can tell you it does stink - if you stop shortly after a high-power application in a high gear. At speed the smell gets carried away, leave it too long before you stop and it has cooled down below the 'stink-point'. Andy Link to comment
JB80120 Posted April 22, 2006 Share Posted April 22, 2006 Dave, There are two distinctly different types of bike clutches, wet and dry. If you are talking about a wet clutch, when it has been abused, the oil takes on the burned smell and it is virtually impossible to get rid of it. Shopping for used bikes with wet clutches, it is common practice to check for the clutch oil smell to see if it has been abused. Perhaps this is the context in which you've heard about "the smell"? As for your RT, it has a dry clutch, and a pretty good sized surface on it as well. I ride the same year and model as yours, ride pretty hard, and I have never had the slightest smell from mine. I'm sure you could deliberately cause it to smoke, but assuming nothing has leaked oil on to it, under even aggreessive normal circumstances, I doubt it would happen. Link to comment
Mulepick Posted April 22, 2006 Share Posted April 22, 2006 Mine was fried pretty bad (see thread for photo) but the only smell I experienced was the smell of greenbacks with little wings on them flying out of my wallet. Bob Link to comment
skinny_tom (aka boney) Posted April 22, 2006 Share Posted April 22, 2006 A slipping (dry- like on an 1100RT) clutch smells just like over used brakes. The catch; it must be slipping to produce the burning smell. A clutch that is "just about to go out" may never smell if it never slips. Get the bike out on the highway, maybe on an uphill, and whack the throttle open. If your engine revs but the bike doesn't accelerate much, then your clutch needs replacement. Link to comment
Unity Posted April 22, 2006 Share Posted April 22, 2006 A motocop from the Spotsylvania County (VA) sheriff's department did slow-speed demos at the Morton's BMW open house last spring, using the clutch and rear brake to stabilize the bike during tight turns and balancing exercises. He said, "It smells like sauerkraut," and several in the audience agreed. --John (I probably would've agreed too, but I don't have much sense of smell. ) Link to comment
RTme2 Posted April 23, 2006 Author Share Posted April 23, 2006 It slipped a couple times last year, while on the highway, in the act of passing quickly. I haven't had that happen again, though I may be babying it just a little now. I have smelled that "used brakes" odor a few times this spring. Fine time for Cincinnati to be without a BMW dealership. Any Cinci riders out there using a local mechanic that you would recommend? Dave Link to comment
DEF Posted April 23, 2006 Share Posted April 23, 2006 You BMW dry clutch folks need to leave the burnouts to the HD guys with the wet clutches........ BTW, the R clutch is not that difficult to replace yourself. Try it, you'll like it.....about a 4-6 hours job with the correct tools. Link to comment
