The 5W shouldn't be a problem - just means it doesn't get too thick and will flow better when cold. It doesn't make it too thin. I have always used a 5W40 (Rotella T6). Yamaha says 20W40 or 20W50 for my bike but there shouldn't be any issues - lower number before the "W" is better when temperatures are below 50° F but should never be lower viscosity than the oil is at operating temperature.[ATTACH=full]5626[/ATTACH]OTOH, the 30 part is lighter than recommended - at least in my manual.
