get this type of clip-on
replace the straight bar with a piece of 7/8 pipe with a bend 2 inches from the end
and you have adjustable rise/pullback.
Same type of idea, but instead of bending a straight tube, just get a typical "drag" bar and cut it in half and use 1 half for each side. You can also mount the clip on clamps on the wrong sides/upside down (so they point up) to get even more adjustability out of them.
I might actually steal that idea. I like that a lot. I was planning on mounting clip ons above the trees, cuz the gl front end is a little longer I believe, so I have room. I'll cut, grind, sand off the handlebar mounts and I want to put led idiot lights in the 4 holes that will be left behind. another idea from someone else here. sorry, I forgot who.
as my front end is now I grinded, etc off the gauge mounts. I have the fork mount speedo from cycleX. anyways it (triple tree) cracked. no biggie, I'm not using it, but I'm wondering if it was the removal of the mounts that weakened it for it to crack. could also have something to do with a bent fork tube.
