i need to sort out getting the speedo correct for sva can anyone recomend the options for the job.
sierra 3.14 diff zx10r clocks
also where is best to locate this unit,is it a once fitted forget or is it something you want to get access to.

speedo healer is the gadget you need, there are others but IMHO this is the best.
have a look at www.bikersdiscountstore.co.uk
I left mine acessable so i could tweak it at SVA if needed but once set correctly it could be hidden if req
