Cable extentions or rerouting for raised bars?

So I'm looking into putting raised bars on my '97 VZ800.
I wanna mount 8" risers and a drag style bar. The bar would sit roughly 2" higher than the stock bar. Has anyone done a similar setup and did you need any cable rerouting or extensions? I am really hoping not to touch wiring as I have very little experience in that area.
Thanks in advance

If you are only going two inches higher you shoud be ok with the stock control and electrical cables. What you might find is that the brake line might be too short.

I'm thinking of 2inch risers or 12 or 14 ape hangers not sure what to go for
