Hello, sfera 50, year of construction 93, about 28500 km only stood for about 1 year in the garage, and now I drove him about 40 km until at a traffic light the good piece went out. Now he still starts and runs with little tours when I open the gas tap. I would say a little more than standing gas. Anyway too little to turn the rear wheel at least a little bit. It stands still. As soon as I give no gas it goes out. When it runs I hear a squeaking noise from the box where the kickst After searching for the forum I looked through the following: Exhaust removed. does not run better only very loud. Timing belts looks good. Spark plug is minimally black on the electrode. (according to the owner not yet 300km old) Air filter is clean. you can look through and is dry. Oil is inside. I have nothing cleaned before the ride, only air in the tires. Why does the part not come on the way. Carburettor cleaning would probably bring nothing fear. to search with search function sfera50 and found no matching post. Thank you Omue
