B11 clutch longevity

[silverbullet]

Hello guys, I have a Breva 1100, for those who have the same can you tell me what sort of mileage you’ve had out of your clutch. I know this can be an expensive replacement so keen to know. Mine has done 22,000 miles so far

Regards Martin

Providing you don't abuse it, change the fluid regularly and it doesn't get oil contaminated or have the centres fall out of the plates a hundred thousand or higher is very easily achievable.

Don't overthink it. Go ride.

Swingarm and shock linkage bearings are a far more likely source of headaches if they haven't been inspected and greased.

160,000 k on a Norge and no problems
Needless to say that mine is nothing special, but I do routinely allow the clutch to be fully "home" before winding on any real throttle.
As in, I do not slip the clutch excessively on take off as you would if engaging in stop light drags or other such chicanery..

Well that's good news.

How often do you recommend changing the clutch fluid Pete?

Just finished doing the swing arm and shock bushes and all good...which was nice

Huzo - thanks for the offer and luckily I didn't need to call in your skills for bush creation!

Every year or 10,000km. For some reason CARC bikes are murder on clutch fluid. It goes black and 'Gritty' really quick. No idea why? Bleeding the clutch is super easy though due to the convenient remote bleeder line.

Cheers Pete - that makes it right about now

I do mine every 10,000 k which makes 16 times so far and there's always black residue to be wiped out of the clutch m/c. I wonder if there is some degradation of the seals where they contact the fluid in the slave cylinder and the whole process is exacerbated by the heat due to it's proximity to the engine..?
The crud would migrate through the system.

67,200 miles on my 1200 Sport, which I believe uses the same two plate clutch as the B11.  I have been less than punctual on clutch fluid changes, but I baby the clutch components, since I know how deeply the plates are buried in these machines.  Just got 100,000 miles out of the single plater in my BMW R100GS.  Had it replaced since the tech was pulling the tranny and has the tools and knowledge to easily and quickly pull the clutch plate.  He replaced only the friction plate and diaphragm clutch spring, and said the pressure plate still had machine marks on it, and showed no bluing to indicate abuse or slipping.

There was an Issues th some of the early 8V's that led to the rear main bearing flange leaking. I had one in and forgot that part of the fix is to leave out the gasket and use threebond instead. It's not a mistake I'll make again !

I had the box out three times before I remembered the service bulletin and re-read it. That meant the last time it was done right! By the third time I'd got to the point where from a running bike with a leak I could have the gearbox on the floor in 25 minutes! Being an idiot hurts sometimes!

Really, doing a clutch on a Guzzi isn't that hard, honestly.

Hmmm..
Neither is landing an A 380 if you've done it 200 times...

Peter, doing a clutch on a Griso or Sport is really no harder than an old Tonti or Loop. Stelvios and Norge's? Not so much but only because of the extraneous munt that gets in the way.

I'd be a touch intimidated.
