Doc, are you going to Spyderfest? If so, how about I bring you a sample kit, fee already paid, so that you can collect a sample of oil when its changed and then mail it to the Lab for analysis. You can benefit by finding out how your motor is faring, as well as finding out how well the oil held up.
In the 998's I found that, depending on brand of oil, the viscosity sheared down to upper 20W/low 30W in as little as 2-3K miles. Really curious how our 1330's will fare but with only 2500 on mine its going to be quite awhile before I get enough miles to have a test done. If interested, PM me where you will be staying and I'll bring a kit.
