This 14 mm x 15 mm motorcycle hydraulic hand clutch master cylinder rod system is designed for efficient fluid transfer.The pump includes an adjustable anchor head with a threaded design to accommodate various motorcycle models.It uses thread-locking compound to help maintain positioning after adjustment.For certain vehicles that use a U-plate anchor, the U-plate can be removed and the pump installed directly onto the pump head using a long M10x1.25 screw.The adjustable range is suitable for many standard motorcycle clutch line setups.On models where the pull head mounting point is threaded, an 8.2 mm drill bit may be needed to prepare the installation area.Installation steps include filling the reservoir, connecting the tubing, bleeding air from the system by actuating the lever, and verifying proper lever travel after completion.
