First up, hi everyone! I've just finished my 1800km journey to pick-up a NSR250R, sadly a bit worse for wear, and without any knowledge of its history.

From what i can tell, mind you a very quick look over, gearbox/brake fluids are spotless, sparkplugs look brand new. Refer to Images. I’m wondering if it has been rebuilt and never put back together. Is there a sure way to check without pulling the barrels off?

Before I start, I was hoping to get some ideas/tips/opinions/expertise on what moves to make.
