Bandit 1200 clutch slave cylinder piston Seal keeps blowing
kamahasanyi posted a topic in Oil Cooled
Hi. The bike is 2006 Bandit 1200 (SK6). The piston seal on the clutch reserve cylinder keeps blow. I changed the clutch. Started it up, heard a clunk from the left hand side, and then saw brake fluid leaking I rebuilt the cylinder and put in braided clutch hose. Go to bleed the clutch, just as the lever gets hard and I can start with the bleed, bang the seal goes again. Anybody have a clue what's going on? I am a bit stumped. Two main candidates: either the slave unit itself is at fault and needs to be replaced or there is something wrong with the right side pushrod (the left looks okay). I think it may be the latter. My working theory is that if the pushrod doesn't move, then the piston can't and the pressure behind the piston blows the seal. If so, clutch will have to come out again: the right side pushrod is way deep in there. I guess there is the third option of the clutch master cylinder having an issue but really doubt it. Please help. Thanks
