Mike responded to my email. They are still doing the mods. I have two bikes that have it and it makes a ton of difference. Before, the sump had to be drained even after just a couple of days. Now I never drain them. Yes, the level in the tank does drop some if you let them sit a month or more but there is always a little oil on the end of the dip stick and if that's present I have no qualms about starting the engine. I just make sure to watch the tank refill before I ride off. IMHO a must do mod on a Norton.
