  2. Can you run full synthetic oil in your fuel for older bikes?

    Hey guys, i recently bought a second hand 1999 WR250 2 Stroke (has YZ250 top end and WR250 bottom end) and i was wondering if i could run full synthetic oil in my fuel? it says in the Manuel that i should run YamaLube 2-R which is full synthetic and ive been running semi-synthetic. Really hope...
