Dear Simon, Glad to see I can communicate with the U.K. Factory. I own a late 2012 961 Sport Commando bought from Egli Racing in Switzerland. Although living in France near Geneva, I was given the opportunity to acquire one of these beauties without having to wait. Paradise Motos in Paris at that time did not have any available and could not guarantee the delivery date. In brief, I had a few problems on the engine that were sorted out by Mr. Egli himself, including a temporary repair of the hydraulic lifters as these had a dangerous factory default. The only way to cure for this would be a replacement of the cylinders. The total bill for the fixing of the few problems was in the range of 3,500 Swiss francs, normally covered by the warranty, but in fact paid by myself and never reimbursed for the reason Norton UK all knows too well. All I am asking is how could I finally obtain a pair of new cylinders from the factory? Shall I come to Donington (am ready to do that if needed) or can these be sent to Paradise Motos under my name and the manpower covered by the (now defunct) warranty?
