Thanks, this is my first bike so I'm still learning new stuff but besides spark plugs, oil, and air filter, is there anything else to do for regular service
you should really download the service manual for your bike.
Check tire pressure at least weekly, preferably before every ride.
Look at the oil level sight glass. The oil level should be around the halfway point.
You need to clean & lube your chain every 3 to 500 miles. Check the chain slack.
Do a walkaround inspection before you get on your bike to ride it anywhere. Look for oil leaks, objects imbedded in the tires.
There are several regular maintenance items. Look in your owners manual or your service manual. Learn how to do all your maintenance yourself. Your dealer is not necessarily your friend. The dealer service department is for warranty issues.
