Yeah, I was horrified at my 100 mile oil change! I had to go to this forum and do a search to find out if this was okay. Turns out it is perfectly normal on a tw. I have a Chinese bike also. I have changed the oil several times on it and never a speck of debris. Go figure....

I usually just let the residual oil drip off for a few minutes, then hold it in a shop rag and thoroughly blow it from the inside out with the compressor. Makes things squeaky clean and no contact with the screen surface ensures none of those tiny little holes get made into bigger holes that could let particulates through.
As SkiPro stated once any debris that is collected by the filters it is not going anywhere. It is trapped and thus effectively taken out of oil circulation and the equation of concern over engine health. In a lot of unrelated filtering applications the worst filter efficiency occurs with clean filters and then gradually improves as a bit of filter cake develops and captures particles smaller than the filter pore size. Our TWs never develop a filter cake though.
Even still the 20 micron or so sized particles that tend to match the engine bearing tolerances have a low capture rate on the mesh filters. Frequent oil changes can flush these fine particulates out.

Get yourself a KN143 filter....more pleats to catch more crap! I believe HiFlo makes an HF143 as well.
When I bought my first NEW bike, I broke it in using the Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power method and it served me well.
It is a point for debate, for sure...but the logic is sound...your call.
Most important bit of information in there is to change your oil after the first 20 miles; that's when the majority of the "wear" occurs and you want to get as much of that crap out of the engine as possible.
Then, change it again after 100 miles...then 500...then follow the manufacturer's recommendations, or your own instincts.
Use dyno oil during break-in...NOT because it is "too slippery for break-in" but because it is so darn expensive. After 500 miles, consider your engine "broken in" and drive it as you would usually.
The following oil change can be synthetic...and I would recommend using a high-quality motorcycle-specific brand...but that's a whole other argument!
