What oil are you running now, What year a model is the bike ??

Well, I always used synthetics lubes. When I was younger in the 80's I learned of the benifits while racing cars and motorcycles. I must admit I started with Mobile1 for 2 years but later learned on Amsoil and have used nothing but Amsoil ever since. Cars, Boats, Airpalnes and Motorcycles all have Amsoil synthectic oil and Amsoil filters.
Most Trucking companies use Amsoil products, taxi companies are using it, etc..... Less Maintance.....
