Thanks All,
Yesterday was forecast to be a great day, so I was preping the New bike, a 1200 Griso, after it's winter slumber. After it warmed up there was a loud 'tappet' like noise, that didn't sound good.
Took my V11 Sport instead & had a great ride. Then back home I adjusted the tappets on the Griso, checked the oil again.
Still the loud tapping, from the right cylinder. The sound rises with engine revs, it doesn't change with bliping the throttle, meaning the sound is faster, not harsher. With a stethoscope I made myself more concerned as the sound seemed to be louder at the front of the engine & lower down. It could be a blocked oilway, starving oil to the roller tappets, but it's new clean synthetic Eni 10/60. So that doesn't seem likely.
Earlier this year, on a clear day, I took the bike over to show off to a neighbor. After the 1/2 mile to his house the bike had developed the same noise. We checked the oil & found that the PO after changing the oil had filled it to the correct level on the dipstick but with the bike on the sidestand, not with the bike upright. Added more oil & the sound disappeared.
Between then & now I have only had 1 ride, because of the weather, a 'getting to know you' ride of 160 miles. The only comment I would make was the bike sounded noisy as I put it away in the barn. But not the loud tapping noise I have now.
I do not have the skills nor currently the time to open the engine up. So it looks like I will be visiting Cadre cycles.
