Grizzly Engine & Transmission 660 Base gasket delete December 19, 2015 I am going to be pulling the jug off of my bike soon, I’m toying with the idea of deleting the base gasket to more squish in the combustion chamber. Does anyone have any experience with this? Thoughts? Etc? Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
