Fitted a pair of 3" bar raisers http://www.mandp.co.uk/productinfo.a...-Round-Raisers
fitting was real easy took about 20mins, no clearance problems with cables and wires.
only an inch taller but makes a real difference.

a few tips
undo the nuts on the under side of the yokes before taking the clamps off,
bolts are used insteed of nuts to hold the raisers on, and need to be M10x75.
use lock tight on all bolts.
