What are the clip-ons hitting that's reducing your clearance?
Tank?
Dash?
Forward part of fairing?
Bottom part of fairing?
To clear fairing with lowered bars, I've done this mod where you chop off part of fairing that normally attaches to tank.
For even more clearance, you can remove even more of fairing.
Someone posted an easy method couple months ago to reduce steering-angle limits to prevent squashed thumbs.
