How does the “X Groove“ work?

On the down stroke, excess fuel wash down and debris are swept into the “X Groove” and exit through the oil drain- back holes, keeping the protective oil film intact on the skirts and cylinders.

On the upstroke, excess fuel wash- down and debris are swept into the “X Groove” and exit into the oil pan, keeping the protective oil film intact on the skirts and cylinders.

Benefits of the “X Groove” • Improved power through ring seal • Improved cylinder wall condition • Improved piston skirt condition • Reduced frequency of required re-rings • Improved cylinder life - reduces amount needed to “clean up” hone cylinders
