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

[tim_tam1785]

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 you guys can help me out ahah!

Yamalube 2r is a great oil and will work exceptionally well in your engine. I've used it in a wide variety of engines from MX, to drag racing to road racing two-strokes air & water cooled all with excellent results.
