If anyone's interested in a bike maintenance/fuel log I made in Google Sheets, let me know and I'll send you a copy. You can also just download the blank sheet as an .xlsx file and import it into your own Google account here:
All you have to do is enter the Periodic Maintenance Chart from your owner's manual and keep a log of the gas, maintenance, and repairs as you ride.
The sheet automatically tracks your fuel mileage, flags service items that are overdue, and makes a list of items that need to be done soon. It also creates a drop-down list on the Log sheet so you don't have to type everything in manually as you're working on the bike.
I pull out my phone whenever I'm fueling and update the gas/mileage/date so I never forget the more obscure maintenance items.
If you want me to make a blank copy and transfer it to your google account, drop me a line.
