They are a fecking nightmare!!! Even my MZ skorpion (Yamaha single) is the same.
Its probably not using oil. As steve says, run it (I think even 30 secs will pump it all back to the tank?? but I bow to his greater knowlege!) And check it again.
Or (if you are curious!)
1 check it cold
2 run it (or take it up and down the street)
3 check it again
4 be amazed by your marvellous oil-generating motorcycle!
We are all going to be rich! RICH I TELL YOU!!! A-hahahaha!!
