ok i have a 2002 yamaha blaster and when i check my oil yesterday it was at half way in the view finder
after i got back from riding i let it cool down and then the next morning i went out and there was barely any in the view finder....
i stood the bike up on its rear grab bar and i then looked in the view finder and the oil was filled from bottom to top
after i put it back down and there was the same amount as before i stood it up

is that enough oil for it?
and does any1 know how many quarts i should put in
i have half a quart in now

thanks
