I went through this exercise with my 13 and had only just enough adjusment - could have gone with another turn or two - didn't think to remove the locking nut!
You probably know this already Philbo - but your pegs will now hit the road much earlier, so adjust your approach speeds to the twisties accordingly.
I really enjoyed the extra length it gave my knee joints when casual riding, but I quickly replaced them with the originals to gain back the better banking angles, as where I live has a good proportion of twisty mountain roads.
Keep us updated with how you get on, and what the new riding experience is like for you.
Cheers, Diesel
