Kawasaki G4 G5 G7 Piston Ring Set STD. # 13008-043 1969 1970 1971 1972 1973 1974 1975 1976

Here is a very helpful item:  This is a new in the package standard size 49.5mm (STD) Piston Ring Set  for the now vintage G3 G4 G5 G7 Kawasaki motorcycle models produced between 1969 1970 1971 1972 1973 1974 1975.  The 49.50 mm ring is for the 100cc models. These rings do not use the expansion ring that original rings set used..most tuners found these could break and cause problems. So the use of 2 quality rings seems to work the best as a modern replacement. These are non-Keystone rings (not tapered) Kawasaki did make some rings that were tapered style and used a different piston ring landing. So check your old rings to compare.  Everything to get your pistons/ engine running nicely again.  G4 was often called the Trail Boss and G3 the Centurion or Bushmaster.  We only sell the best! This is a top-quality aftermarket item shipped new in the package.  Correct for part # 13008-043.  Will fit the stock Kawasaki piston perfectly. Good stuff if you are riding or restoring one of these cool bikes.  That is it! Thank you!
