Just thought I would share my recent experiences when suffering from intermittent overheating rear brake on my 2005 V11 Le Mans with 10000 miles. All appeared fine at the pedal so I suspected rear calliper which I inspected and cleaned, both pistons fine and moving nicely, test ride and still binding. Removed master cylinder which at first appeared fine but I decided to rebuild so ordered repair kit from motomecca. When the kit arrived the problem became obvious! The master cylinder piston was not returning fully due to a build up of alloy corrosion within the body of the master cylinder which was squeezing a nylon sleeve which the piston slides up and down in thereby causing pressure to be applied even when pedal not pressed. I have now rebuild the master cylinder and problem sorted. Just something to watch out for as this obviously happens over time. If you look inside the bottom of the cylinder where the push rod enters you will see the black coloured piston within the white nylon sleeve held in place by a circlip. The piston should return all the way back to the circlip, level with the bottom of the nylon sleeve. If not you probably have the same problem as me. Repair kit was about £20 including postage so probably worth doing next time you change fluid. Hope this helps someone else! Jez

Can anyone help with this? I have a 2003 model v11 Le Mans which was first registered in 2006. It has covered 10000 miles from new and runs really well but being new to the bike I am a little worried about a noise that appears when I pull in the clutch at standstill with the engine running. It sounds like a worn thrust bearing, not quite a rumble but more of a metallic roughness. Once the bike has had a run and warmed up it is not so noticeable and of no concern when moving. The clutch feels fine in operation with no stiffness or slippage. It may be that this is all perfectly normal but being new to Guzzi,s I would appreciate some reassurance! I absolutely love the bike and other than rebuilding the rear master cylinder which was seized have had no problems. Thank you for any suggestions, Jez
