I do it hott after letting it run on the stands for about 5 minutes... If you are running thicker oil, this will help get the oil warm and somewhat thinner consitancy. Then drain this will allow the oil to flow out better then cold oil which would be thicker. Thus taking more time to drain and tend to be more sticky and stick to parts instead of coming out... I replace the filter with a OEM suzuki filter with the oil change. I also change my oil every 12-1,500 miles. Just to make sure. The manual says not to replace the filter till 10k LOL yea right why would you wanna put new oil into a dirty filter. IDK either...
