Whilst I can normally see why certain mod's are done, I take it those above weren't planned, so what did you hit?
no GSXR top yokes can just be drilled as they aren't strong enough, so either you'd have to add material beneath and bond it in place or go for something like the
Raask risers which clamp around the tubes.
bear in mind you'll also have to relocate the speedo take off (as the GSXR doesn't have a front wheel one), but then it looks like you'll be needing a new speedo as well anyway.
Generally getting the right brakes for the forks is the option to go for, but adapter plates can be made, but why make life hard
, just about any sports bikes will be better than the SV standard items.
Cheers Mark.
Edit: Yeah the LSL conversions are good quality, but it's a whole top yoke and expensive .
