Quick question, I hear about guys changing their oil every other ride, every third, etc... this seems kinda rediculous to me because I ride almost every day when the weather permits. Had 4 strokes all my life and maybe changed the oil once a season or so. I run mobile 1 RT-1040 which is exact API SH rating as yamaha manual says for this bike (full synthetic) and just did an oil change with K&N filter. So I'm pretty much looking for opinions on how often folks change their oil. Usually I will change mine when it looses it's golden color and starts to turn brown but waaaaay before it goes unclear.
