its like 600 miles since i did the last oil change....

 

If it was me I would change it back to synthetic just for the peace of mind. I have heard that it is bad to go back but I have no first hand experience. I would just sleep better at night with synthetic back in it.

 

IM not really good with motorcycles yet since i just purchased my first one, but i know in car's they say it can be bad to go from Synthetic to conventional because of the minerals and particles in conventional oil. But it is ok to go from Conventional to synthetic, but once sythentic they say keep it synthetic.

 

I thought there were mixed mineral/synthetic blends of oil. If the two can be mixed together, why would it be bad to go from one to the other?

 

They have full synthetic there and just regular as you have for this link. I use the regular. I had synthetic in my last bike and it made the clutch slip all the time. I changed back to regular and it was perfect again.
