many thanks for all your help,she's now running very well.
have been out and covered approx 80 miles with no problems at all..apart from one and fairly major for me.
i simply dont fit on it,i weigh more than it and when laying on tank my head is in front of the headlight/above the mudguard

soo,afraid shes going up for sale,ive got to get a bigger bike no question about it.
am very pi$$ed off but she's going on ebay uk i think,i have put her here in the meantime: http://www.swapz.co.uk/swapz/automotive ... some_bike/
there maybe a duke owner with a different model that has one that is too big,lol.
