Spark Plugs Changed and Air Filter check - oil?

Well I was out earlier doing some maintenance on T'Pol. I bought plugs back in June to change them around the 7500 mile schedule and I am now just below 10,000 so I thought they should be changed. The hardest part about the whole process is getting the tank lined back up. I am going to be installing a tach soon and I think I am going to take some silicon lube and lube up the rubber mounts so they go on and off easier.

Anyway the plugs are in. The old ones looked great. Took time to check the air filter which really needs replaced. I will be ordering some parts again soon from Kawasaki Parts Nation and get another air filter.

When I removed my air filter housing cover there was oil in the bottom, is this normal? Is that part of the crankcase breather?

Going to change the oil again this week as I get close to 10k. Just trying to keep up on maintenance.

Things I plant to do for next season are a front and rear brake fluid flush. Font brake pads, they are at 4/32" as of the last PA safety inspection. Thinking I might do a cooling system service next year too. I really wish we had replaceable fuel filters

That oil in the bottom of the filter is most probably from the crankcase breather.

It is what I figured. There wasn't much at all but since hit n run incident a few weekends ago where both bikes got knocked over I wondered if any oil leaked out. I am guessing not.

There is a small hole in the airfilter casing that leads to the crankcase breather hose. It vents the oil back int the air filter case. Large amounts of oil might indicate another larger problem but small amounts are normal.

I am guessing it was about 3-5cc of oil if that. Like blood a little oil goes a long way.

Three easy fixes: 1) Disconnect the hose from the airbox and install a small breather from an auto store on the hose. Rotate the rig up under the fuel tank and cap off the nipple at the airx ;2) Longer hose to the airbox but route upward off the cyl head then down to the airbox. 3) Clean the airbox more frequently. I did #1. But #1 or #2 Both methods allow blowby oil to drain back to the crankcase.

Well now that I am aware of this I will remove the cover more often, once an oil change at least, and clean it. Seems like the best idea to me.
