Thanks for the links. ISTR there were a few Hondas with the big bar inserts? The bars on mine are currently Risomas and I think those and Renthals are thicker walled and wont take a lot of bar ends? Might have to stick some expanding rawlbolts up there!
They are too low for me and I need to change them anyway...
Had a nightmare tonight as the cheap crappy speedo mount someone made up broke! so I thought i'd take the twin headlights off to get at the bracket and whilst I was there i'd try and fit the single headlight I have for it. Then i saw the loom, which is all taped up and slightly confusing to say the least and then I realsied being an S originally it had twin headlights and I assume both headlights are on all the time on the S. Shouldn't be too difficult once i start unravelling...
