Was working on my dad's mates motorbike tonight, harley davidson its a chopper 2.1 engine he was coming up to a junction & the clutch failed with it thumpin away he struggled to stop it as you could imagine it would pull you up the side of a house.

Anyway i took the resiorvior cap of & it popped the brake fluid is grey looks like old gear oil. Anyone ever seen this before? The bike has never seen rain what so ever dosent even get washed it gets polished its a show bike so i have ruled out water.

Im pretty sure he topped the brake fluid up would mixing 2 different fluids cause this ?

 

This is the bike here

 

up

 

no body

 

i would try fresh fluid and go from there

 

Will give that a go bike has done just over 300 miles scince built
