Welcome to the forum. Plenty of helpful folk here to give you any assistance you might need, with a dash of piss taking thrown in. Your thou sounds like a good find, however fresh juice is a must before you attempt to start it and be prepared for the likelihood of blocked jets, depending on how it was laid up. If it runs, then an oil and filter change would be next on the list. Semi synth 10-40 is fine. Give the tyres a good examination as well, as 4 years just sitting may have taken it's toll. Good luck and keep us posted. They like pics on this site but I'm focced if I know how to do that. :lol Enjoy. :thumbup
