Throttle wire for R4 1289?

[Torkilr4]

Hello!

I have tried to make the original short R4 845cc throttle wire function on the R5 TS engine, but it`s difficult to make it open completely. Is there an other wire that would fit quite good? The wire from R5 is maybe good og the R4 as well?

Tips and tricks is welcome!
