Beta Evo ran clutch Master cylinder out of oil

Featured Replies

Hi, only had the bike a few weeks was out riding and clutch stopped working... got home to find the master cylinder empty which now I know why the clutch lever was always wet. It was coming out the piston every time you pulled the lever, bought new seal kit spent hours trying to bleed and noticed oil dripping from the piston again so ended up banging new master cylinder on, seems to bleed up quick but it’s got clutch drag and can’t move out of first gear when the bikes on the floor ??‍♂️ I’ve tried reverse bleeding etc and can hear clutch plates moving when pulling in the lever, is this still trapped air or do I need to look elsewhere?

Remember that sometimes the pipe curves higher than the master cylinder and that is where the air gets trapped. Preferably you need a rising line towards the master cylinder with no high spots so the air wants to return back, then just keep pumping and releasing and trapped air will work it's way back to the master cylinder..
