I decided to do some cosmetic work on my breva 1100 06, The swing arm was stained and had some salt marks on the gear box ect .THings got a bit out of hand and have ended up taking the engine out and seperating the gearbox ,I would like to inspect the condition of the clutch plates but I have not got the tool to re-align the plates is there any thing to look for whilst it is assembled to give an indication of wear ? The bike has done 20k mainly two up there was no problem but seeing as I have got this far I would replace it if there was significant wear ,one thought was to take the gear box input shaft spline off and use it to align the plates like I saw in an earlier post and then return it to the gear box.
 
With only 20 K miles and without the tool I wouldn't bother to look. With the tool I would. The only way to check for wear on the plates is to measure them, but unfortunately Guzzi doesn't provide a wear limit specification. I do a comparison to new plates and make a judgement call. Do inspect the hub gear for wear. If you see grooves starting to wear (you shouldn't at 20K) then I would replace both the gear and plates. Is there anyone you can borrow or rent the tool from?
 
thanks for your reply perhaps i am being over cautious ,The input gear looks fine,thanks for the reassurance and yes that is London England .
 
Once upon a time (2000-2007) I owned a lovely little Kawasaki W650. Once the bike turned over 40,000 miles, I constantly worried about the clutch, and whether it was ready to give up the ghost.

I ordered plates (multi plate wet clutch .... probably half a dozen friction plates and a similar number of metal plates). After taking it apart, my buddy checked the thickness of a couple of the friction plates and asked " ....... we're changing these plates why?" Practically no wear.

I appreciate that the Guzzi dry plate clutch is a totally different design, similar to BMW dry plate clutches, but unless you've really beat up on the clutch, I'd think you have several thousand miles left before a clutch replacement is called for. My 1200 Sport with similar or identical clutch is at 45,000 + miles, and feels as good as new ..... no slippage, and good take up. I expect it to last at least another 45,000 miles.

The times (with BMW) I've had clutch issues was when the engine rear main seal failed and the dry clutch plate got saturated with engine oil. I always keep this mental picture of the little clutch plate that's transmitting all the torque and hp, and treat it with respect, especially since it's located where I don't want to go.
