Hello all, I am unfortunately at the end of my nerves. I bought the Yamaha Virago 535 from dealer, first hand. Year of construction 1999 mileage 7000km The moped is in a very good condition, everything was also made by the dealer – service carried out fresh through our master workshop – carburetor overhauled – spark plugs new – spark plug new – oil and filter change The following problem, hot or cold, when pulling gas in idle, the speed always hangs a short time and goes very l There’s no problem when I drive, but I come to the stand and try to drive, it doesn’t come forward as if it’s swallowing. In addition, as soon as I pull 20% of the gas nothing comes, when I give 30% it pushes forward suddenly. Am I at speed and give gas everything good. Only this advance. Of course, no direct injection but my feeling is that something is wrong. Another note, in idle and when releasing gas, the exhaust is banging. t though nice but something not right with the moped. Dealer tells me that the seals have been checked, my guess that runs too lean or pulls false air. I drove just since purchase 100km and had once filled Super Plus. Hope that someone here can help me thanks !! LG Daniel
