I just finished installing a 2" pair of ROX risers. They solved the forward lean problem for me....I am 5'10. I bought a Transalp clutch cable from Honda Canada ( although that bike was never sold here). It was $20.
The throttle cables were too short, and I could not find a custom pair for under $400. I ended up adding 5/16" to the right side steering stop. That solved the problem of tight cables when the handlebars are turned to the right. The bike has a lot of steering lock, so the the reduced travel is insignificant. Keeping the stock cables, also makes cable replacement a lot easier and cheaper.
I checked mine and I can't get enough slack for either cables or the brake line even with only 2" risers so I am looking at going even higher since I have to change cables and brake lines.
I found this company selling Flanders handlebars in whatever size and shape you want for about $120...

And this company selling cable making and brake line kits,
https://revivalcycles.com/ They have a pretty good instructional video about making cables and they sell some nice kits...
.
And I am thinking about adding one of these brake unions and possibly using Revival Cycles brake line making kit as well...
https://www.mgcycle.com/index.php?main_page=product_info&cPath=110_114&products_id=3153 . I am hoping adding the union and pulling the brake line with the banjo fitting at the master cylinder and tying it to one side of the union and building a brake line to whatever length it needs to be to reach my new handlebars and tying the other end to the union, both banjo fittings. Or just buy a 12" jumper line already built somewhere?
I am pretty sure I can do the whole thing, handlebars and all for about $250. I have a lot of measuring and studying to do before I order anything. Not even sure if the brake union is an option but it looks logical enough to me and it eliminates the need for a Honda proprietary brake line for an ABS model where it goes from the master cylinder and attaches to a little connector and changes direction.
Too bad Helibars discontinued their rig for these bikes, it would have been a lot easier. But they have disappeared even from E-Bay.
