Adjusting angle of clip-on, Mille Gen1

I would like to change the angle on my Mille from 2001. I would like to push the ends a bit forward to get more front lean and less pressure to the outer parts of my palms.

There is a clamp, holding on to the front fork, and also a screw that securs the clamp won't turn unintendedly.

My question is: Will the clamp be enough on it's own to secure the angle even during hard braking and a lot of pressure on the clip-ons?

Thanks,

Tommy

All aftermarket or race clip ons do not have the small screw you mention so again as mentioned the clamps are what secures the clip ons to the leg. The screw just assists with locations the same angles 

I've got aftermarket clipons now with 2 bolts on each fork leg. But even the stock ones which have a single bolt to the fork leg were perfectly fine for me. 

If you do what I said with moving the fuse boxes (or I guess even if you don't), I found you can get them pretty close to symmetrical just by setting them so that at full lock they have a couple mm clearance. Assuming your frame and subframe is straight, which it should be really. It's close enough for government work I think as even if they are slightly uneven, you adapt very quickly to it. 

I found the same thing as you with pressure on the outsides of my palms with the stock clipons. Like they point far back but my hand is stubborn and holds them at the angle it feels most comfortable. I was able to push them forward enough to get my hands more flat on the grips. 

I also dropped the clipons a bit down the fork leg to help me get more weight over the front. Though due to the air ducts I was only able to get so far.. 

At times I look at other bikes in the paddock and am jealous for how much space they have. The front ends of these bikes are pretty cluttered compared to most modern sport bikes.
