Two standard piston ring sets, one for each cylinder, for the Kawasaki FH601V, FH641V, FH661V, FH680V and FH721V and the horizontal-shaft FH601D, FH641D, FH680D and FH721D: the 675cc V-twins at the 75.2mm (2.96 inch) standard bore and 76mm stroke. Each set has a top compression ring, a second compression ring and a three-piece oil ring. They replace ring set 13008-6058. Pistons (standard piston 13001-7007), wrist pins, gaskets and valves are not included. These engines were also built with 0.50mm oversize bores of 75.68 to 75.70mm, which take the 13025-7002 oversize rings, so measure the bore before ordering. Hone lightly, check end gap in the bore, fit the rings marked side up with the gaps staggered, and use a ring compressor on assembly.
- TWO RING SETS, ONE PER CYLINDER - Two complete standard ring sets, each with top and second compression rings and a three-piece oil ring. Pistons, wrist pins, gaskets and valves are not included.
- FITS KAWASAKI FH601V, FH641V, FH661V, FH680V AND FH721V - and the horizontal-shaft FH601D, FH641D, FH680D and FH721D. All are the 675cc V-twins at the 75.2mm (2.96 inch) standard bore and 76mm stroke.
- REPLACES RING SET 13008-6058 - The matching standard piston is 13001-7007, which is not included. If your parts list shows 13008-6058 for the rings, these are the rings.
- STANDARD BORE ONLY - These engines were also built with 0.50mm oversize bores (75.68 to 75.70mm), which take the 13025-7002 oversize rings instead. Measure the bore before ordering.
- FITTING THE RINGS - Hone lightly so the rings have a crosshatch to seat against, check end gap in the bore, fit the rings marked side up, stagger the gaps and use a ring compressor going into the cylinder.
