Oil vent filter

[jlkepley19]

Any ideas why I'm spitting quite a bit oil out of the filter

Are you talking out the vent hose near the front left downtube?

If it's a lot of oil, and you recently changed the oil, it's probably overfilled.... and therefore being spit out of that crankcase breather.

If you've not changed or added oil lately, the it should be just a drip or two of residue that will normally come out of that tube/filter. I ran a long hose out and down the side of the bike fishing it through stuff so that it can drip or blow out just behind my pipes on the right side. A long tube will not allow stuff back up into the motor, and give any residual oil a long path to eventually drip out of.

I suppose if you really wanted to, you could use a mini air filter from Home Depot inline and catch oil? I did that on the PCV line of my F150 to keep all excess oil from getting back into the intake. It works!

I cut a couple of inches of that small hose off. Then I cut a couple of inches of a larger diameter hose and put it over the smaller hose just tight enough to stay on. I twisted some paper towel into the larger hose to absorb any drippings. Kinda like a Warrior Oil Tampon.
During a oil change, just pull the oily paper towel piece out and replace it with fresh paper towel piece ...

Look in the forum: The Welcome Mat.

There is a link to a Yamaha video for how to correctly check motor oil level on DRY SUMP Yamaha motorcycles. Use that to check true level. My guess is (as others have said already) its almost certainly overfilled.
