Good To Know
Q: Is this kit compatible with the Honda Rancher 420 from 2009? A: This kit is designed specifically for 2007-2008 models; later years may have different bore sizes or cylinder configurations, so verify before purchase.
Q: Do I need to replace the wrist pin or circlips? A: The kit includes the piston and gaskets but not the wrist pin or clips; they should be inspected and replaced separately if worn.
Slight variation in finish or dimensions may occur between production runs, and confirm compatibility before ordering.
