How often should I have the fork serviced? Will playing with the oil weight affect sag (i.e. thinner oil)?
Depends on how often/hard you ride. Also depends on manufacturer. Marzocchi's can go years without service while my mantiou needed service every 6months.
Thinning out the oil will change the damping characteristics how quickly the fork compresses and rebounds. If you REALLY want to customize than it is worth playing with, but learn to do it yourself. Paying a shop to always do little adjustments gets expensive.
