With all the excitement of the new M8's, seems like you can hear some crickets on this tread.....
Well, I can say that I just rode to my dealership to get my 45K mile oil change done. Had some Dino oil for the first 2000 miles or so after my 117" upgrade.
My wrench said oil was good, no signs of it being dirty and that it pulls really awesome! Still haven't got my final dyno tune done as I'm looking at getting some pre-owned 110" heads and l plan on sending them down to John Sachs, to let him do some magic this winter.
I will still say, anyone thinking bout this upgrade, Go For It!!!
