use a full synthetic oil or not ???

Switched to full synthetic last oil change. Had to satisfy my curiosity. Used Motul 7100.
No difference performance wise. As others had mentioned in other related threads, I did find engine noises were a tad louder. Not of the bad kind though.
Curiosity sorted, I will be switching back to my old faithful Motul 5100 semi next oil change as I see no benefit in paying the extra $20 or $30 per change for the full synthetic as I change my oil on average every 8 weeks.

Your not going to find any benefit in one oil change. The benefit is in the life of the bike if you ride hard in extreme conditions.Any good brand oil will be ok with regular changes. The best thing for any engine is regular oil and filter changes including air cleaner.
I don't do that many km's so I can afford the more expansive oil. I use 300V even in the tractor(DRZ400). Nothing like the good oil!
