In my life long experience, I have seen a break or clutch bleeding that fails or takes a long time because, people chose to lay the handlebars straight. while bleeding you should have the bars set in both sides to have the air pockets leave from the cavity of the cylinder. The air hole must always be at the highest point. If you try to do the same thing on your C50 break line you will fail.
Hi Alex, Thank you for your input. Here in Western Pennsylvania we are having rain the next week. One day without rain. Time to work in the shop. Ride safe. Norman.
