Before I jump into buying parts for a rear shock rebuild and re valve I thought I would run this by you guys. The current shock is leaky and I doubt it has ever been rebuilt. I plan to ride this bike in mostly supermoto trim but I also swap the dirt tires back on in the winter and ride the trails and dunes. I believe that I am going to need parts 11 and 14 to rebuild my shock. 11 should be what causes the oil to leak down the shaft right? Is there a rubber seal on the valve stack to seal the piston to the wall? Edited because I am dyslexic.
