Aye Bill,
Good to read you on here again.
As for the Scarver! Whilst I had my Funday, I went over to our nearest BMW dealer and they had a number of these in stock. All of them had rust forming in the various seams and nooks and crevices of that 'tank' and elsewhere on the frame. The knicker elastic drive may not have been in doubt, but the paint/chrome etc finish appeared naff!
A friend was delighted with his new 800, no problems from the elastic, but the body paintwork and finish on the crankcases, was the subject of 3 warranty replacement claims! Cheap alloy castings and cheaper plastic coating with minimal mudguarding and salt on our roads, apparently don't mix!
You seem to have a good one and long may you enjoy it!

My regards, Bill.
