138190056 M8x35 Exhaust Stud fits on the exhaust side of the clone or predator cylinder head to mount the stock or aftermarket exhaust.
Most racing applications require the exhaust studs or bolts to be safety wired to prevent the bolts or nuts from backing out. Most opted for using Allen cap head bolts predrilled as an easy replacement for the studs.
The M8x35 Studs fit most of the 196cc 6.5hp Clone engines, including Honda GX200, Ducar 196, Ducar/Tillotson 212E, Tillotson 196R/RS, Tillotson 212R, Tillotson 225RS, Ducar/Tillotson 212E, Predator 212 and BSP 196 and 212 cylinder heads.
Torque Specs: 200 in/lbs
