Welcome to the Vulcan madness vila.
Where do you live? (If you fill out your profile, it will show on every post you make.)
I thought about moving my r/r to the front too, but it seems to be a lot of work to do for a small possibility of benefit IMHO. Splicing in 6 wire extentions gives you 12 more connections to potentially loosen or corrode while riding. Soldering the joints and covering them with shrink wrap insulation will minimize those concerns, but it is till messing with a currently fully functional wiring harness.
For maximum cooling you would want the r/r mounted off center so the front tire is not blocking direct air flow. Mounted low, it will be exposed to high velocity water, sand, gravel and other assorted debris coming off the road and kicked up by the front tire.
If mounted high by the rad, as Cspinner mentions it may be partially blocked by a windshield, rendering it not much more effective than if mounted in the OEM position or by the rear footpeg.
I have relocated my r/r to the left footpeg area, and it does not detract from the lines of the bike IMO. That is a subjective question to each individual though.
I don`t normally suggest painting the r/r, as it can cut down the efficiency of heat transfer somewhat. Still, it is an option if it will make the r/r enough less visible and objectionable to you in that position, if it were black instead of aluminum colored. I`m sure someone here will object to painting a heat exchange component like the r/r. But consider that almost every radiator ever installed in a cage or on a bike is painted black, and it`s primary function is heat exchange too.
I had to take the battery box off to clean it of some rust, then paint it when I removed the r/r for relocation. I painted the battery box bottom exterior with high heat white (or maybe silver ?) colored paint, with the idea that it will reflect some heat from the goats belly away from the battery, and prolong its life. That may be wishful thinking on my part, but I already had the paint and it didn`t cost me any more time or money to do it that way.
I personally do not plan on removing the goats belly, as I want the low end torque more than top end HP and speed. I like the looks of the stock exhaust ok, and it is loud enough to suit me, though I would like a deeper sounding tone. A higher reving VN750 cc engine is never going to rumble like a Harley though.
