50wt oil is recommended in the ninjette when temps get over 105*. If your location has that types of temps, I'd fully agree that using a 50wt oil is a good choice. If not, your providing more internal drag for the engine at lower temps. With the small amount of HP these bikes produce, I would think the lightest (proper) oil you can get away with would be the better choice.

I use 40wt in my bike as that's what's recommended.

switch over to a full synth at 1000 miles... you'll be glad you did.
