Hi guys and girls, A friend of mine has a 1999 650 Dragstar, and its not been loved for a while now. Its not been started for at least 8 months, the battery is long dead, and its currently being kept outside (last 2 months). My question is, how much agro would I be looking at to get it started and back on the road? Its mot expired over a year ago. A friend of mine has suggested the engine will be ceased now from lack of use, is this the case with these virago derived vtwins? Im trying to get a rough idea of the cost involved in recommisioning it back to the road. Any help would be much appreciated. Seems a shame to let such a bike rot. Thanks. Stuart
