Didn't you say in an earlier post that the R31 cable works and fits?
Anyway... I've temporarily shortened my R31 cable by cutting the eyelet off at the end, pulling the black outer sheath off, cutting that and rejoining using some fuel line and areldite. I then sourced a new eyelet from a motorbike shop and re-fitted that at the suitable length.
Long term plan is to get a custom one made up, or possibly try the S13/180x cable... Thats if anyone ever decides to reply to their pm's on NS.com....
Washer bottle... Not sure, but also need one for mine... I'll prob go a GReddy one, or one of the fancy ones available from yahoo japan
