I have yet to do an oil change on my bike, and the previous owner never changed it. What type of oil should I run? I have read the previous posts about problems when switching to semi or full syns so I am not sure.

 

I use Mobil-1 full synthetic in my F-2. Which bike do you have ?I've heard on some models there is a clutch issue.

 

Repsol...full synthetic...not the blend...the full synthetic...15 W 50..

 

I have a 1990 CBR 600F. I heard that once you go to a full syn you cant go back so I just wasnt sure what to use not knowing whats in there now.

 

1.That's a falsity...

2. You won't want to go back.

You're bike starts easier, quicker, smoother, especially noticeable on cold mornings, or when your bike has sat for awhile.

It acclerates and shifts easier, smoother, requires lighter touches on the controls.

Synthetic REALLY is better than the cheap **** they make for cars, and better than the cheap **** they make for bikes as well.
