Personally I'm baffled as to why you would want to use an old 900 in this way. On a 92 bike I don't even think the suspension is very good.
If you do, though, you'll need to change the oil very regularly (as Ali says) - much more often than a 4-valver - because (obviously) the oil is doing the cooling as well as the lubricating.
