to answer your question....
you will want to get a throttle cable from a bike off ebay.... i recommend the universal one as is onger than most so you can trim it to size
also those bodies are for a silver top VTR and to get to 130bhp you would need to cam it aswell!!!
silvertop inlets are wank so you would gain a fair bit from them but personally i would fit a newman 280 or piper 285 cam to utilise the most you can from the bodies
as for stand alone choices..... with these i woud choose omex as KMS has shoddy wideband llambda and omex can be mapped just from the TPS (throttle positioning sensor). tbh though whereever you get it mapped i would go for what ever they reccommmend as they wil be used to the specific system diagnostics of the ECU they tell you
