Stelvio engine covers

I’m new to Guzzi’s and a bit dim anyway. I own a 2009 Stelvio with 20,000m can I take the engine shrouds/ covers off especially the one that covers the engine dipstick I see that the new engines don’t have em fitted but wondered if they were there to direct airflow and assist cooling ? Also what brand of oil is recommended I know it’s a 10 / 60 but hear the Guzzi’s are finicky with oil type! Thanks

hi i have run with out these covers for 1000,s of miles no problem . stick to oil thats recomend to stop any issues with cams
