Motorcycle Repair: clutch 96 suzuki intruder, clutch master cylinder, suzuki intruder

Question
all the sudden quit working.what can be the cause of this?

Answer
Tom,This could be a toss up but check to see if the slave cylinder is even pushing the clutch push rod in. The clutch master cylinder could be out of fluid or bypassing and not pushing the fluid down to the slave cylinder. Check the system it uses DOT 3-4 brake fluid in it. It may need fresh fluid only.
