What is this on RH Crankcase cover?

[Kukku]

I just noticed what looks like some type of sealant in the marked area. Is there supposed to be a bolt in there? Can someone explain what is it? Thanks in advance!

[xtrock]

Dont worry, its there for no reason! Original its plugged, if you have sealent someone maybe have drilled it up?

[awolxt]

No sealant on mine. Not sure what its there for though. Ill attempt to upload a photo of mine.

I have no idea why my photos keep coming out this way up.

Just another oil feed option if used on other bikes with different setups.

Thanks for all the replies ... mine doesn't look like it was drilled but it is covered with some sealant. I thought it had a sheared bolt in there which seemed strange on a bike with just 13,100 km! I'm relieved that it's normal .... I'm enjoying this bike a real lot.

Yes its a good bike for its purpose, but if you go riding a Thunder or R1 it feels like the XT dont have brakes, engine is falling apart and its more or less like a moped. So stick with your XT and enjøy

I have an ST1300 as well as the XT but although it has more power, comfort, sophistication etc, the XT outperforms it in terms of fun.

I tour on the ST but I still have ambitions to take the XT on a long trip at some time. I'm gradually modifying it for such a trip and have to decide what direction to take.

[xtrock]

Yeah cant compare them, XT is fun for what its good at. I recomend KTM if you want something in the middle, they have good brakes and enough power for the bike.

It's what is left of a hole drilled at the factory as a oil passage way. they drill the hole from the outside of the cover into the oil filter area then plank the end of the hole so no oil escapes from the engine. and all the oilways they drill connect up thus creating a path for the oil.

I have a CBR600Fi for touring and spirited runs ..... I bought the XT to take it easier, enjoy the little countryside we have left here and general commuting and so far it rocks. I just need to learn how to wheelie it now for trail riding.

Thank you for the technical explanation, I was hoping to get one from someone. I assume the oil passages are there for heat dissipation?

No oil passage ways are for oil to pass along to get to another part of the Engine/Gearbox. Radiators are for heat Dissipation.

There is no way to "Mold" the oil passages so when they make the cover, material is in place where the oil passage should be and they are then drilled as stated above.

If you look at carbs, same thing. Some passage ways are not even drilled as the carb casting is used for various models that require a different setup and they only drill the ones needed.
