this might sound off the wall but I can't see the chrome triple tree in that image?
but in all honesty when you lower a bike you've changed the geometry, obviously if the bike widens as you lower the clips you will run out of room to function naturally...
I cant tell all thats been done but it appears you have removed the stock triple setup and pushed the forks up to lower the front, since the chassis is wider the lower down you go the bars are colliding due to increased width?
apparently your only action is to install after market adjustable clip ons in an effort to maintain desired effect, odd the installer didn't alert you to that situation? maybe he just threw the parts on and didn't bother to check functionality?
so, remove the spacers or whatever, thats ghetto..
you have the choice of removing the spotting pins off the clips so you can move them, not advised as they are not designed to maintain position with engineered grip, the pin holds them in place, not the torque of the bolt you tighten them down with, (if you over tighten the bolt to add grip you will ultimately pinch the fork and fubar functionality...
ultimate fix is after market clip ons, they have more clamp area and you will notice this, prolly 3 bolts all in all compared to 2, also they cipe the interior mating surface for grip so you can still maintain the 8lbs of maximum torque and not have them move around on you...
simple really, aftermarket trees require aftermarket clips, installer should know this, not a prob though, keep the monkeys away from your bike, order online and install your self...
the manufacturer of the tree will offer clips...
