Can someone tell me what oil to use for NSW, as i have moved from Cairns. I have been using 50w because of the heat up there. Recommended oil grades state that should be ok, but a bike shop i rang said to go 20w50, but according to the oil chart it's not the best for temp's here. I'm not going to ride in the cold weather.Thanks for the help..i'm confused, it doesn't take much. It is a 2000 model twin cam.

Thanks for that. I will use 20w50 now. Just about everyone i knew in Cairns used 50w oil, so i just did the same. I change the oil about every 5 or 6k, never 8k that they state in the manual.
