oil level bolt question 2006 510SMR

Does anybody know the exact size and pitch the bolt is. I bought a bike last week and when I went to change the oil I found the oil level plug as a smaller American bolt that had been siliconed into place. I would really like to get the right bolt/threads and see if I can get it screwed in and sealed then go with a new clutch cover sight glass.
Thanks,

Nice, but do not need the oil fill plug, just the oil level bolt thread size and pitch, thanks anyway.

thanks, I was hoping it was a NC thread but just didn't know. I was afraid they would throw up some metric fine thread that is hard to find.

Thanks!!
