Oil change time any one running amsoil ?

Got a tote full of full synthetic 10 40 anyone haveing leaks or abnormal friction part wear on there old kz motors with syn? I knkw its no good on ol 350s as the lifters dont always spin on the cams and unevenly wear, actually seen a notched lifter in my brother car due to this.

Here we go again! :woohoo:
And yes I have first hand of one 350 thats been on the mobil 1 synthetic diet with close to 1 million miles on the origional lower end! :woohoo:

Tons of people using Amsoil syn in bikes. It's one of the best.

I have been running Amsoil 10w40 Motorcycle oil for the last 3,000 miles, and have not noticed any abnormal leakage, no problems with the clutch slipping etc.
I feel as though the engine is quieter also.
