Great web forum, the best I have found around, informative and friendly. No slagging like some do. Found you about 3 months ago while seraching on how the replace belt. All done now and a new battery put in about the same time during the cold January we have just had. Problem now is I have just jumped in to my Sien and there is not a sign of life! New battery was bought in Jan and charged to the hilt before putting in, Anybody got any clue as to why it won't start please inbox me. I last used it 2 and a half days ago. There has been no probs for the last couple of months.
