I'm not worried about the pump, from the control it was and it's working it's just a precaution, however I will follow your advice.
For engine oil the bardahl 10w-50 is ok or better 10w-40. Thanks for the tips are always great.

Re: important Siris system valves
So first is to confirm your are talking about the oil that goes into the tank and lubricates the engine? That Bardahl is fully synthetic but will be okay for your motorcycle. Some owner prefer semi-synthetic or mineral oil. It's a personal choice.
Transmission oil that goes into the gearbox is completely different you should only use mineral oil because synthetic oil will cause clutch plates to stick together.

If you have used and like this oil it's ok
I would always use mineral oil in the gearbox that is what was put in the motorcycle in 1970's. I use cheap mineral oil and change it every 3000 miles as there is no oil filter.
