Changing Oil By Hours

[magoconnor]

Hello. 

Im currently not able to mount a speedo on my bike, execpt for a gps but well I dont have a spare one. 
I read someone on this forum talking about changing the oil by the hours instead of keeping track of the miles driven. 

My question is how many hours does it roughly take, to drive 600 miles? 
Or how many hours driven between oil change?

I count by fill ups of gas I get 60 miles to the gallon so before 10 fillups I would change .
I have a index card that i have under my seat that I log miles and how much I gas fillup so I can trach average gas mph i also have when I swapped the motor and when I put on new tires.
I have 3 scoots so its easier if I keep those maintance records with each scoot .
As far as hours figure every 20 hours run time if they want to change every 600 miles.

Get a bicycle speedometer if you want something to track mileage and speed. I've used a few and you can calibrate a decent one.
