I'm due a change of oil - wondered what the consensus might be on left/right fork oil grades and quantities that people are using? It's for road use if that makes any difference.
That is a good point about oil levels, by increasing the air gap/ reducing the oil level will soften the suspension and increasing the level will make it harder due to locking up. Although a different BMW my Urban GS needed a much larger air gap to improve the ride due to hydraulic locking on large bumps. I do have an R100gs also, so I have do experience of both.
