If you only take a pillion occasionally I'd just spring it to your solo weight. In which case, the main thing to do would be increase preload, some of the aftermarket shocks with castle nut adjusters are an arse to adjust, the oem style is often easier unless you drop more notes on a remote hydraulic adjuster. My Wilbers was a bastard to adjust but it differs from one make to another.
