When using a bike engine with a hydraulic clutch, what size master cylinder are people using and what distance from the pedal fulcrum to the clevis on the push rod?
Many thanks

The bike master is the one to use if you can, its been done.
I used a Wilwood 5/8 one which worked ok.

I’m using a landrover one, but I would probably use a bike rear brake cylinder next time

Another shout for using the original bike part. Have to be a bit careful re lever arms etc but it's the best option IMHO.

I'am currently doing some drawings for using the original bike master cylinder. Its going to be cable operated from the pedal. the other end of the cable attaches to the bike clutch lever. This way I get lots of adjustment for feel and travel.

Not sure yet where to position the master cycling, may even be on the bulkhead.
