I did reassemble it but the spring seems very weak(hardly any resistance)....so its going back for a replacement.Rang them this morning to be told by a message that they are closed till new year and as items are supposed to be reported faulty within 48 hours i'm not sure how that will work?
Reassembled the bike with the old rear tensioner fitted but have done the "stop" mod so if it goes it should not be to drastic!!....Oh and the bike sounds lovely
