Good day, so slowly I despair at my Virago. It starts and runs perfectly in the stand. However, it usually reaches only 100kmh and has no power at a certain speed. Yesterday, during a test drive, she drove but suddenly much faster (170kmh) and also had full power with relatively many misignitions occurred while taking away the gas. When I wanted to test another lap, she ran again only 100. Before these two tests, I had the membranes a built and tested in the light, whereby I had forgotten one of the large springs when assembling (which are the responsible ones?). When I had then installed the spring again it ran also once a little faster but this was only of short duration. Now it runs unchanged 100 and does not come to the maximum speed in coupled condition (under load). The spark plugs are new the ignition system was measured recently and the air filter is apparently only a tube under the chrome lid rec hts. Since I don’t know if I should take the whole carburetor apart now or it’s just a problem of attitude I thought, I’ll ask here. I wanted to go to a workshop, but all around there are no dates available until May 10th. Maybe someone from you near Kiel or Eckernförde who could help me? Could also drive some more routes.
