Just want to give you some feedback about this repair kit I got from Wemoto. I couldn't find many offers in the internet for these kits, so maybe this information can be useful for some of you.
Even though Wemoto lists this kit for Moto Guzzi, it was interesting to see this is a Yamaha repair kit...I guess it will be much easier to find parts for a Yamaha than for a Guzzi...
About the kit: - The piston is exactly the same that came originally in the bike (11.9 mm) - The piston spring it's a bit shorter, and the spring diameter that contacts the cylinder is a bit smaller. Maybe it could still be used, but I preferred to install the original spring - The dust boot it's a bit longer than the original. The collar has the right diameter, but it is not as thick and stiff as the original. Because it is longer it gets a bit smashed when the clutch lever is fully compressed. Don't know how long it will last...We will see - All the other bits are of no use...even the circlip, that strangely this cylinder doesn't uses.
Anyway, it's case no other options are available, this is a valid solution.[You must be registered and logged in to see this image.]
Yup, all the CARC bikes use the same master cylinders. Remember though that whether it will cure the problem is dependent on the state of the bore of the cylinder.

Hi Matias
If you want to replace the Wemoto dust boot with the similar to original one, oem part number is AP8133522.
By the way, this is the most expensive tiny piece of rubber I've ever bought. For the price you will get a nice brembo plastic box and an instruction manual written in probably all existing world languages (dust boot is on the right side of the first photo)

Well done Fruk I bought the wrong 12mm seal and boot set
However in the process I found a more modern 12mm Brembo clutch pump off I (think) 696 Monster. These were widely available new on eBay. That was going to be the cheapest alternative to the radials
