Are your bike water cooled ot Air cooled? I was looking from an Air cooled standpoint. I change my oil around 2500-3000 miles so far 4 times this year.
I was using Mobil 1 15w50 and getting it in a 5 qt container for $17.88 at Wal-Mart but they have changed the formula so thought I would try Rotella T Syn for $12 for a 4 qt container.
