On a brand new bike, it seems that engine oil pressure which lubricate clutch push rod bushing is pushing back the clutch slave cylinder piston while engine is running. I have to pump the clutch lever to get it to work. As soon as the engine stops, the return spring behind the piston push the piston back on the push rod and clutch works fine. I removed the slave cylinder and I can see that oil pressure pushed on the shaft ball bearing seal. Where this oil pressure is supposed to escape? I’m new to these engines, dealer is 450 km away and I want to deal with it by myself if it’s an easy fix.
