Hello together, I have a Honda Bali SJ50 (bj. 96, 9600 km) and some questions: 1. The first is that I want to change the spark plug once but I have no idea where it is. I once took a picture with my guess. If it is there, then I know but ned how to get there… ^^ I guess it’s the thing in the middle with the 3 points on it… 2. I want to change the air filter sometimes, can I just do it without any experience? and where is it? 3. And di e rear brake is totally “low” there is in the back so no screw on the brake (not at the helbel but at the rear wheel) can I just turn them out a little bit so it gets harder? 4. Do you think it brings what if I no longer refuel the 4€ oil from the country of purchase but Castrol Power 1 Racing 2T? (bring in respect of motor protection that the scooter drives for a long time, possibly even a little more power?) 5. I bought a carburetor cleaner from Liquid moly, always nice in engine, brought nix for w as is the kick then there? Vll. have you a few tips for me and answer. Greetings Patrick
