Clutch wont bleed up
To bleed these properly, Firstly remove the resovoir cap,you then need to remove the slave cylinder, tip it to the right slightly just as if you were leaning into a corner, Whilst holding it in this postition, compress the piston all the way in and let the spring push it back out, do this about 5 times and you should see air bubbles pop into the resovoir, makes sure the fluid level is ok, Too little will draw air in, too much and it will overflow onto the bike !!! You don't need a mityvac system, just a LARGE syring and peice of pipe, push fluid in via the bleed nipple on top of the slave cylinder and as air always goes up, it will automtically rise upwards to the resovoir.
DO NOT use 5.1, normal dot4 is better in brembo hydraulics, also check the slave cylinder seal is ok, they are prone to wearing and will make it virtually impossible to bleed correctly, New one is £12 from Aprilia..
