New 1600 owner. Oil screen question. #pic#

[alwhite00]

My buddy just bought a 08 1600 . 33,000 miles. Fairly clean bike. I recommend for him to drain the oil at the screen. This is what he found. He said it almost looked like nylon brush bristles. Couple very small metallic pieces.

Any ideas?

It is possibly the first time the oil has been drained via the screen. I wouldn't be too concerned about what you found.

Mine had the bristles too. About 5in long.I think it might be from the camchain guide. Nothing else in the engine that it could be.
This poxy site wont upload a photo, but trust me, it was much worse.than that.
I know of a bloke in Russia, that pulled the entire guide out through that hole. If i hadn't seen the photo's, i wouldn't have believed it possible.

A bike with 33,000 miles certainly should have had the oil changed at least three times by that miles amount. Perhaps the oil strainer screen was never removed and cleaned even though the oil and filter was changed regularly.

I disagree about no concern for the debris. The comment about the debris from the cam chain guides is likely right. But that may also indicate the can chain guide tensioner needs to be updated. Or possibly replace the cam chain guides.

The engine needs to be stripped down, to the bottom of the barrels at least, to replace the parts. https://www.kawasakioriginalparts.co...D6F&country=GB

I cant see enough detail in the small photo to determine what is on the filter screen.
If there are bristles it could be from a small brush that they used to coat parts with oil during assembly ? I certainly would not be tearing into the bike if it were mine. I would clean the filter screen and install a new oil filter and oil and run it for 1,000 kms and check the screen again. If there are more bristles then I would investigate further.

I agree. mine never had any crap in it the next time i changed the oil.

I changed the oil on my 1600 last season, which included cleaning the strainer. Found nothing in the strainer to indicate anything, and no nylon evidence, bristle or otherwise.

I plan to replace the cam chains and guides in my 1600 this winter when I tear it down.

I put new chains in mine. It wasn't such a bad job to do, because i just took the heads off, and threaded them through, then joined them up with hard links. If you are replacing the guides, i think you are going to have to go below the barrels to get at them. Not a job i fancied at the time.

MY 1600 will be torn down to the cases to repair the tranny (2nd gear) so it'll be the right time to replace any wear items in the engine during the rebuild. Plus, I am installing Mean Streak heads and throttle bodies, and 1st through 4th gear from a Mean Streak.

Well, thats what the screen is for, to catch crap before it enters the oil pump. If she's running good, you've changed both filter and oil, and double check your oil press. by removing your sending unit, screw in a mech. oil gauge to get a precise reading.
If all is good, I'd say its ok.
Could've been some crap in a filter, someone used a dirty funnel adding oil, if the engines ever been opened up, could be brush bristles from the mechanic....never know....

Good on you for getting into it mate. Me, i'll pour another large one, and bark at the moon for a while.

[alwhite00]

I told him to run it 1,000 miles and change the oil and see what the screen looks like.

[redjay]

Let us know how it works out and if he finds anything after 1,000 miles

If this bike has never had the oil screen cleaned, I wouldn't be too concerned. I think that advice you gave is sound. Clean it, and then check it again with the next oil change. That will give you a better idea of how things are doing internally. The screen is doing exactly what it is supposed to do. It's catching crap before it gets to the pump.
