Bill, I like to do my own work on the 4s and I came to the realization that since I do that - I can easily justify buying stock Ducati replacement parts. I often buy aftermarket o-rings, fuel filter. But I always use the OEM belts, oil and air filters. You are saving hundreds by doing your own work. Just my 2 cents because I have been there too.
