Ok, back home after about 1,600km's that included about all types of riding except single track...
I would declare this mod a success! - bike didn't miss a beat, lower fuel consumption trend continuous, recon it's as good as stock when new!
Can't comment on longevity yet but with the replacement filter elements available I'm planning to swap them out every 20k km...
So far so good... Happy to answer any specific questions anyone may have.
