jet force TSDI 50cc

Hello! I'm repairing a Peugeot Jet Force TSDI 50cc indirect injection scooter, but the problem could also occur on other scooters like Aprilia, anything with fuel injection. After many hours of searching for a solution, phew! 🤬🤬😪😫😫😁😁👍👍 I bought a compression gauge kit on Amazon. I bought the spark plug from a Peugeot motorcycle dealer. I replaced the air injector for nothing, but if you're interested, I got it on eBay from a German seller for around €95 including shipping. Yes, it's incredibly expensive! Brand new compressor ordered on order, purchased on eBay for €132, and it's worth its weight in gold! 🤪🤪 Compressor: https://www.ebay.de/itm/274092363870 Compression tester: https://www.amazon.fr/FreeTec-Coffret...
