I'm changing oil AGAIN ! Last spring I changed to Amsoil, bike seemed to be OK, then it started 'whining' again so I bought a quart of MotorCoat and added a few ounces.
The 'whine' got louder but I let it go until this year. After the few rides I've been able to do so far (about 300 miles) it seems like the 'whine' is still there and VERY annoying.
Right now the bike is sitting in the garage dripping, has been for 20 minutes or so. I'm going back to Mobile One and NO Motorcoat - see how that does on the ride to DC this coming weekend.
I guess I should qualify the above statement - my habits include camping with our Travel Trailer, fishing and I work a part time job. All of that means that I may get around 3 or 4 thousand miles a year. Changing oil twice a year IS expensive when it's $10 a quart and not enough miles to warrant a change.
