So I recently changed the oil on my Buell with the Harley Davidson oil and it's running different. When the bike warms up after awhile my oil light will come on and the chain or something starts getting really loud. The bike sounds different too out the exhaust and the rpms stay high when you come to a stop they don't drop all the way. But it goes away and runs normal again and then will come back randomly and the light comes on. The belt tension is right 1/4" movement cold but I'm just confused on what it could be or what to do. I'm thinking on going back to mobile 1 v twin oil and seeing how it runs. I've ridden the bike like this for awhile and it hasn't gotten worse or better. Any help or suggestions would be great
