NHTSA's summary

SERVICE BULLETIN M1359: 2014 - 2016 TOURING - HYDRAULIC CLUTCH LINE REPLACEMENT. PURPOSE: REVISION. A leak may occur on some Touring, CVO Touring, Police Touring and Trike models equipped with hydraulic clutch. The leak may occur when the line is replaced or when a P&A clutch line is installed. The area of the leak is at the joint where the clutch line attaches to the secondary clutch actuator (right side of the transmission). Required Dealer Action: Use Snap-on Flare Nut Socket (Part No. GAN85087B) and Snap-on Torque Wrench (Part No. QJR117F or similar) to tighten flare nut. Each time clutch line is installed or torque is adjusted to determine if leak is still present, bleed the clutch system.
