I'd take it to your local machine shop and have them mill it down. Really fast and not very expensive. You'll end up with a much smoother finish than if you grind it yourself. I had it done to the 550 top clamp, and it turned out really nice.
Just because a pro does the work does not make it a safe idea, there are enough dangerous homebuilds on the road right now. I don't think a fast and smooth triple top will save my flesh from meeting the pavement if it cracks and breaks during a hard brake pull.
I also have the tools and the knowledge to do the work. (I work with a mill and lathe almost every day) I am not a "machinist" (because I don't have the patience) but I am getting pretty good.
That being said, have you had any issues with it? Cracks? Does it handle different?

I've done it to my 350F and have had no problems.

I'm interested to know how it would affect larger cc bikes specifically. I considered this purely for cosmetics and I won't compromise stability.

Do you have a TIG welder? If it were me, I'd weld up the "holes" underneath the bar clamps first, then mill the clamps off.
Having said that I've seen bikes where the clamps have been ground off and the holes left in place. Can't say I've heard of them failing.

Re: Shaving Cb750 triple trees.
Here's a shot of the top and bottom tree, and you can see in the shot with my hand that shaving down the bar clamps would leave very little metal to keep this important structure stable. My roommate advised having the bottom boxed in by a welder, but at that cost I can just buy the dime city triple. I vote against milling/grinding the OE tree at this time.

Shaving Cb750 triple trees.
I shaved my 350F but still plan on getting a billet one from DCC when I get the money. Price isn't bad and you can't have too much billet goodness.

Split personality, I fake being smart
I would have it sandblasted underneath and welded up.
Really don't like the look of them just chopped off.
BTW, with tele forks, there is very little stress on top yoke, it onlt has to stop fork legs 'tilting' forwards under braking (and back when it hits a bump but that means it's under compression)
