Andreis,
When I did my GSXR conversion I used Gilles Vario bars. You can get them for standard SV fork, the clamp is just a different size. But they are mega expensive
Before my fork conversion I had LSL raiser bars, which were much better than standard S clip ons

This is a uk shop, but I'm sure they're made in Germany.
Straight swap for S clip ons, with no need for longer throttle, clutch or choke cables. You have longer brake lines already.
Still expensive though
