Hi, just purchased a 2103 California custom. A previous owner Millie GT. I haven't ridden a guzzi for about 8 years so a huge learning curve. I have changed engine oil penrite10w 60 , filter and gearbox penrite 75w 90 full synthetic and air filter.The drain plug on gearbox had metal slivers along with brass slivers in the oil with metal partials. The wasnt serviced for 18,000 klms by service book. Both oils where dirty . Any thoughts recommendations?I was thinking change again at 5,000 klms and inspect.
