This is why our bikes aren't getting enough oil through them. I just had mine rebuilt and there is alil metal from breakin, but the rest is gunk. Probably from loctite. There was also a little grass on this screen. I was going to wait to check b/c normally I check it every 3-4 oil changes. But due to my motor getting rebuilt and I don't even have 4hrs on it something told me to check it... I'M GLAD I DID! Sad thing about it... ALOT of dealers steal have no clue about this screen.

1st pic is after it was cleaned and ready to put back into the oil tank

2nd and 3rd pics are completely disgusting...
