I don’t think I’d have to mod the tank at all. For some reason people cut out the lip area of the hood seal in a couple spots. Not exactly sure why. Superjet tank is easier to get in and out with out removing the b pipe it appears ( I have an actuall fx1 pipe). I was doing some mock up, using fx1 and sj tank. And the sj tank is easier to get in and out. I want it to be secure when riding so I may install a ufo mount for a new spot for my strap hooks, as well as one of those stock sj tank wedges.
I actually had no issues with my pipe running on that front motor mount last season. I rode a lot and pretty hard too. I’ll keep an eye on this on my install.
