Good day together! So slowly I want to carry out the annual maintenance of my scooter and have a few questions or I would like to have general tips on the individual points. The following things have to be done: 1. Engine oil (change) As on the photo the oil looks really good (dark yellow). Should I still fill in new oil because the oil is a little over 1 year old or can you use it even further until it is black? I am about 600 km last Jah 2. Oil filter (filter sieve) (clean, replace if necessary) I’m not quite sure where to find the oil filter. I believe in the bottom right where you fill the oil? Do you have some tips for me how to do this best? Do I have to drain oil before? Does oil come up to me? 3. Drain of the intake noise damper (clean, exchange if necessary) I have no idea what that is. I also find nothing on the Internet. Can someone explain to me what it is, Where do I find this and how to clean it? 4. Fuel line: No leaks or cracks (check, clean, adjust, replace if necessary) I’m not 100% sure here either. The fuel line probably goes from the tank to the carburettor? So leaks have not yet occurred to me. How do I check this best? Do I have to dismantle the seat here and then look at the hoses? 5. Tyres: No cracks, wear and pressure (check, clean, adjust, As I said, I drove about 600 km last year. So mMn still look good. But would like to have another opinion. (see photos) 6. Brake fluid level / no leaks (check, clean, adjust, exchange if necessary) I looked at brake fluid today. Seems to be still brim full. The small round window was at least full with liquid. Brake also works. Bonus: The scooter was now a few months oh How do I best do if the scooter doesn’t start or the battery is empty? Should I buy a new one? Should I try charging it with a charger? Start the scooter by kickstarter and recharge the battery by driving?
