my risers are single bolt ones from I think a CB500 I didn't drill any holes in the yoke as there are holes in the fzr yoke already . my wireing and clutch cable was just about long enough I just had to get a front brake hose made up.
Yep forgot about the holes already there for the clipons.
Plenty of single bolt risers about on ebay.
May have to start collecting bits to do it.
Thanks for the reply.
Aha I have a carbon plate over the top of my yoke so didn't realise that there were holes there already, are they already threaded and if so do you know what size.
If you take the cover off you should have two rubber bungs just pop them out and there are the holes with allen bolts into the clipons.
Probably 8mm,not sure if they are threaded but be able to bolt through anyway.
not sure but I don't think there threaded as the thread is on the clip ons. I think I used long studs on my risers so I could also use them for re mounting my clocks.
