Thanks Patman. That's one of 2 places I'm looking at mounting it. But I'm running the IMS 4 gal tank and I'm finding that I have to remember to take that into consideration, because where it may fit with the stock tank, it won't with the IMS. I currently am fashioning a bracket to mount it to the left side of the the front frame downtube using the left fuel tank mount point.
What a pain these braided lines are to twist into the right orientation. I may take the line down to a guy I know of locally that can make/repair hydraulic lines/hoses and have him shorten the one that comes with the kit and also reclock the ends so they don't have to be twisted into their final orientation. He did a great job on my streetbikes brakelines.
I guess since there's not any "how to" help out there for mounting this kit to the XR, that I've found anyway, I should document my install for others reference.
