There's not much to switching brake lines. It should come with new crush washers, and sometimes with banjo bolts as well. Do the lines one at a time. Match the line to make sure you're swapping out the correct one. Remove the old one, and as you remove it, route the new one to make sure the routing is identical - use a wire tie to fasten the old one to the new one if necessary before pulling out the old one. This will ensure the new one is routed correctly.

When installing the new one, use the new crush washers. Put one washer on the banjo bolt, put the banjo bolt through the line fitting, put the other washer on the end of the bolt sticking through, then screw it into the master cylinder or caliper. Make sure you torque the banjo bolts properly, 22 ft-lb.

When finished, bleed the brakes, and you're done. Be careful throughout the process to not allow brake fluid to contact painted surfaces.

Where did you get your brake lines? I'm looking to do mine as well on my 83 interstate.

I've done this to both my bikes , and got the lines , washers from J&P Cycle Products . I went with Goodrich lines as they were clear-coated and there was less chance of paint-rub damage . Just be careful when measuring lines , and take into account the length of banjo fittings when ordering the lines . As long as your original banjo bolts are in good shape , I would recommend using them over buying "new" ones .
IMO purchasing the 35 degree banjo fittings for the front calipers is a benefit to helping "shape" the lines to get them "around" the triangle shaped bracket on the lower fork leg . , and giving them a good "flex" position for front-end travel . The lines get that "looks right" , appearance also .

I put the HEL lines mentioned in the previous post on both my GL1100 and GL1500. They're excellent quality, and already cut and made exactly to fit.

I just got some stainless braided lines from Galfer. Going to install them soon, but am trying to figure out if I need any protective sleeves on the lines. The old lines, which are rubber, have thick sleeves at places where there is some possible friction. The new lines are PVC coated, but not sure if that will be enough or if I need to get some additional sleeves. Unfortunately, can't reuse the old ones because the new lines are so much thinner.

As long as there is no obvious chafing points (and there shouldn't be, if they are routed correctly), the PVC cover is fine. I use the OEM rubber bushings (I cut them off the old lines and glue them in place on the new ones).

Raw braided stainless brake lines without a cover (where the braid is exposed) are extremely abrasive, and should not be installed without covers installed on them first.

Thanks! I actually found a solution...Some vinyl tubing of the right ID/OD will slide into the old (rubber line) covers.
