2014 KTM 690 oil screens

History
I have a 2014 690 endure. The bike has about 1,300 miles on it. I bought it new. I am doing its second oil change. The first oil change was at 600 miles. Changed oil, filters and cleaned the oil screens. This time I was going to change the oil and clean the oil screens and not replace the oil filters.
Here is my question!
I drain the oil, removed the first oil screen, the one next to the drain bolt and the oil in the screen was dirty just like the drain oil. I removed the second oil screen, the one that faces forward and the oil was clean not dirty. Maybe some has a better understanding than I do and can explain why the oil wouldn't be dirty. It seems to me if the oil is being pumped through the engine and the filters were doing there job, the oil would be dirty.
Thanks
LaPorte

Sorry I don't have any answer to your question. I changed my oil and filters at 100 miles then again at 600. Both scrrens and filters looked about the same on my changes.

Hopefully someone can provide more information for you but curious, if your going through the trouble of draining oil and cleaning screens why not change the filters at the same time?

It's all the same oil from the same engine. Right? I bet your perception of the oil draining from the front screen is due to lighting. Shine a flashlight thru the oil as it drains and it looks quite clean. In bad light it looks dirty...

I only change my filters every other time. It does save time and money. But I change the oil a lot. Every 2 rides on my 450 and filters only when I adjust the valves.

It was weird, the oil from the drain plug and the oil screen next to the drain plug were dark as it should be. When I removed the second oil screen the oil in the screen was clear like it was just put in the bike. As if the oil had not be circulating through the screen.
Maybe I am doing to many left hand turns LOL

I have not looked at the oil flow diagram for the 690 (if there is one). Still, I would bet $$ if there is a blockage to where the front screen passage is not flowing .. you would have bigger issues.

The oil is definitely going through the whole system or the engine would have stopped running quickly...

The screens do filter differently though, the left side one and drain plug pick up stuff from the gearbox and the right front from the crank side. The transmission gears create a lot more metal grindings especially when the engine is new and still breaking in so I'd say what you are seeing is normal. One of the needle rollers in my gearbox shat itself so the gear was wobbling around and wearing the ones around it, drain plug and left screen where full of shavings and the right front screen was absolutely spotless every time.
