I can see it now....I'm gonna end up with an S&S air cleaner on everything. I made up another "B" series backing plate to adapt to my "E" series carburetor.... and it just rips now ! All kinds of response, and it just runs better (than the Linkert style, 7" round style). That round air cleaner didn't like wind or rain much either - but I've never had a problem with the S&S teardrop in those conditions. Now just need some nice weather. I'm still riding short runs, so I fulfilled my 2018 goal again of riding every month.
