Obviously, what Jeff from S&S says makes sense, [and isn't it nice that he has taken the time to come on here and advise us?] as HD stuff is easy to get hold of, if not exactly terrifice value for money, I changed my oil and filter at 300 miles and used HD V Twin 20/50 and an HD screw on filter, and will have another change at around 1000-1200 miles. The oil that came out looked as clean as a whistle, but then again, microscopic bits of metal and other cr4p wouldn't necesarily show up to the naked eye, and I feel better knowing the oil is new, especially when you consider that this is what cools the engine [other than air of course.]
I have fitted an oil temperature guage to mine, and it is interesting to note that the temperature will fluctuate quite widely between 40c. to 65c. over quite short periods. I haven't had to run in heavy traffic yet, so don't know what it would go up to without airflow to the cylinders.
Interestingly, my Caterham 260 Duratec runs at around 80c. to 100c. and being watercooled, with an inline oil to water intercooler, is pretty consistant, so the Mog is running quite a lot cooler than a standard, but tuned, 4 cylinder water cooled engine.
I'm not sure what 'V Twin' oil does that standard oil doesn't do though? Anybody know?
