XT600E engine oil overflow where?

Hey guys!

Can anyone tell me where in the heck is the engine oil overflow on the XT600E?

I went to buy the 3.3litres needed to make a complete oil change but I think the guy put 3.5litres in the 5litre water bottle...

I'm asking because I got some oil that is going on to the downpipes right next to the midpipe connection...

the only engine oil lines I remember of seeing were:
  • the crankcase breather (next to the e-start motor)
  • the oil line that goes from next to the crankcase breather line, beneath the fuel tank and attaches to the left side of the backbone.
  • one larger line which part of it is in metal tubing and goes from the right side of the backbone down to the engine and also attaches next and behind the e-start motor.
  • another is the one that goes from the bottom of the frame(in the front) down to the engine.
  • and the last one I remember is a metal tube oil line that attaches next to the oil filter housing and on the top of the crankcase with two oil screws and 4copper washers (two on each screw).
Am I forgetting any?




btw.. I checked the oil bleed screw on top of the oil filter housing to see if the oil was circulating and......I just unscrewed it and only lifted it a very tiny bit and I got an oil shower lol

I dont ever remember seeing one on my XT... Oil overflow is not something i've heard of. You can get oil coming out of your breather (check your airbox, its prob full of oil) which is usually where any surplus gets forced through.

You're best just draining the oil into a clean container and put the right amount back in.


If you're getting oil dripping down the downtube, maybe its where it was spilt when filling or if you've REALLY overfilled it, maybe an oil pipe has been dislodged.

3,3 is too much, thats for when the engine has been apart and all oillines, oilpump and so on is dry.

You need around 2,9ltr for yours when changing oil and filter.

Run it nice and warm and check the oillevel.

If theres too much oil, it will puke it in the airbox, as the crancasw breather is routed in there. It takes a while to do so though.

Jens, that's what happened mate well, sorta! :P
The engine was "apart" and without oil (pratically empty) in it for three years
When I said sorta it's because the only the middle crankcases weren't opened so I guess you're right..

I drained just a bit from the oil level gauge "hole" with a boat fuel pump and some clear rubber tubing...about 150ml..

I'ma recheck the oil in a bit and will probably take a little more 250-300ml... and recheck the oil level..


Well at least I found where the oil is coming from.
The crankcase breather pipe had a split on the end (which I've already fixed) and it's spitting oil out of where the e-start motor fits in to the engine LHS casing..

So Yeah, too much oil..


Thanks guys!

Well, I found the extra crankcase oil breather! lol

When I got the bike back from my mechanic when he replaced the broken cam chain and both inlet valves he attached one screw to the carburetor with some duct tape..

I never imagined where it was from!
So, after letting the bike warm up for a bit I looked at where the oil was supposedly coming from I saw that the crankcase breather pipe I fixed the other day was kinda kinked to I toke the e-start motor out AGAIN...

With the e-start motor out I rotated the crankcase breather hose so it didn't get kinked and then was when I noticed what appeared to be a screw hole on the LHS engine case (looking from the RHS to the e-start motor area)...

Guess what?!

That screw that was duct taped to the carbs... it's that stupid freaking screw that sits inside the LHS engine casing behind the outer casing of the e-start motor (where the clutch cable is hold with a bracket) that attaches the LHS engine casing to the cranckase!

wtf!?!

well, at least now I know where the EXTRA crankcase oil breather is! lol

And since I'm not in the mood for waiting two weeks for a new e-start small LHS engine cover gasket I'ma just use some liquid gasket which I'd already used some there to replace the gasket without any leaks!

Will probably need to get some more oil.. 10€ per litre TEXACO 10W40 semi-synthetic..
Great oil but bit expensive.....
