I've only had my SR185 for a couple of months, and I'm trying to give it fresh oil for the first time (had relatively fresh oil when I got it, so I was told, though I suspect that the bad gear changing of late could be due to old oil). The trouble is, the sump plug, which is on the side of the block, won't budge. I figure some WD40 and a good half hour of 'worrying' it should get it loose, but my problem is that I don't know in which direction to turn it. Any guesses? Is there a typical direction for these things?
