I just got done installing Galfer brake lines on my '04 R1. I ran into some issues and wanted to share and hopefully save some folks a bit of frustration.
The top banjo bolt for the '04 Brembo master cylinder bolts from the bottom, which is tricky enough to deal with. However, even worse, with a bulkier double-line aftermarket setup, there is basically NO clearance between the fork leg and the throttle cables to get the banjo bolt aligned and threaded in. After a lot of cursing, I realized the only reasonable way to get the bolt in was to disassemble the throttle cable housing so I could move the throttle cables out of the way.
That said, the top bleeder on the Brembo MC is a great addition, and I've never had an easier time bleeding a brake system (once I got the damn lines on). My brake lever is hard as a rock now
