Im an idiot!
I was serving my brakes on my K1200s and change out all the fluid in the abs pressure modulator. All went well until i went to tighten the vent caps for the front and rear circuits. One of the caps snapped off as i was tightening it. I really didnt apply too much pressure either. Crap plastic!
In any case, Its either macgyer something together or order a new vent line from germany at a cost of $100can ( plus shipping I would imagine)
Does anyone have ideas on how to proceed. I dont think there is any pressure behind the cap, i believe its just an overflow for the circuit.
