Junk in the crank case.

[Johnhaley]

So I’ve removed my cylinder bank, bought a full gasket set so might as well use it all. After removing the cylinders I’ve been cleaning all the gunk built up around the base of the stud bolts and around the base of the cylinders. I’ve done my best to keep it from falling into the crank case, but a little bit has nonetheless. I was planning on just flushing it with lots of oil, seems like the only option besides opening the crank case, which I will avoid like the plague. Any ideas from all you gurus? Thanks

Not that it matters much for your question, but please create a signature with your bike year and model in it. it helps anyone trying to answer questions, and you’ll never forget to include that info. Go to Settings at the top right of any page. Then you’ll see the signature links on the left hand side.

You could take off the oil pan and see what falls out. If the set you bought includes that gasket, you might as well. If that gasket you remove is original, it will be a chore to remove the remnants. Hopefully you bought OEM gaskets.

Got the signature squared away.

The set I bought does include the oil pan gasket so I reckon I’d be removing it anyway. I didn’t buy OEM, I would probably spend more money than I paid for the bike on gaskets if I did.

You might be buying OEM gaskets anyway. Reviews are very mixed on all of the aftermarket brands. Good luck with the ones you bought. Seriously. Let us know what brand you bought and how they work out. More data is always a good thing.

Goood youll be amazed by what congregates over time.
Pan off was in gas. Dry on delicate setting
Pan off will let you clean the sump screen too

With the pan off and a basin underneath, liberally splash kerosene down the centre hole where the gunk got in. Plan on using at least a gallon.

For the future, when the carbs are off you can get in with a pressure washer front and back, really give it a good squirting, spend plenty of time between the fins especially where the studs go through this will at least massively reduce or remove the dirt that can fall in also do it again after the head is removed put rags in the chain tunnel and cylinders to stop any overspray carrying dirt down.

This has got to be in Nessism's 10 mistakes thread somewhere. I wonder how many people have had this happen. I feel like IF I get to that point with my 850, after blasting with the pressure washer, air hose, leaf blower or whatever, I'll still lay it over on it's side and pull the cylinders off.
