I changed the air filter, Clutch cable and rear brake shoe now @ 10200 kms. Any idea on how many kms we should change the air filter? Also what is the gap between the service durations and at how many Kms do we need to change the engine oil?The recommended service interval for a Royal Enfield Classic 350 is every 3000 km or every 6 months. It's best to change every 3000 km or once a year at least, because RE uses mineral oil and it can deteriorate in viscosity if it's not used often.

Air filter can be changed every 10,000 km or so. But clean it at every service. Haas 5c indexer manual. Clutch cable is one thing that keeps getting cut on an RE. (I have a Classic 500 and that's one spare I carry with me always). Replace the clutch cable also every 10,000 km as a precautionary measure.
