Some questions on the Honda XR200?

[bowen]

Got myself a new Honda XR200 dirtbike and so far, about 200+ on the odometer yet. Good performance. My only concern is that maybe the engine is generating too much heat. Or maybe it's just me cause it's my first dirt bike. It generate so much heat I have to angle my feet to get some of it off my lower shin. Oil level is okay. But I really can feel so much heat on my lower shin part. Would fuel type has something to do with it (93 or 95 octane)?
