Well, we can't offer much advise until we know where it is and how big it is.
Clean the bottom of the engine then let the bike idle up to operating temp until you can see the oil begin leaking.
If it's a gasket then replace the gasket. If it's leaking through the sump itself then remove and weld or replace the sump.
Pictures would probably be helpful.
have you wiped it all off to see where its coming from? Maybe with some engine degreaser to get it all cleaned up. Then start it and watch closely. Make sure you remove the side farings from the entire lower section of the bike.
If an oil change was done recently and the crush washer not replaced with a new one then it could be a possible solution. I made that mistake once myself.
Okay, those are not oil leaks.
They are merely fluid drains to the spark plugs.
Any fluid that gets onto the top of the engine will run out of there.
If oil is coming out then you most likely have a leaking valve cover gasket or the valve clearances were checked recently and some oil was spilled then.
You should clarify whether oil is actually leaking FROM the exhaust pipe or from a crankcase leak above and is dripping down to the exhaust pipe (presumably around the collector box area). Given that the 07 is an underseat exhaust model, you might also notice any condensation which might appear as oil dripping from a loose header to tail pipe clamp.
Ideally, we would need further info and perhaps a couple of pics to offer a definitive response.:smile
I can'#t exactly work out the location, but it looks to be coming from the crankcase. I just can't see how you'd have clean oil coming from the exhaust pipe. I have an 04 model, but can't look underneath now as it's garaged in the dark. I'll have a further look in the morning and report back.
It's worth mentioning there shouldn't be a hole in the exhaust, unless your model has one for draining condensation. As a worst-case scenario, you might have a shot valve seal or piston ring and THAT will force oil into the exhaust pipe, but generally not to the same degree of flow seen on your video.
So its a tiny hole that's under the exhaust. The hole looks like it should be there it's under every exhaust pipe like a drain for condensation which my guess is for the spark plugs? I did my valve check recently and have had this oil issue since. So i replaced the head cover gasket and when I went back in to replace it i had a little oil on the ignition coil which shouldn't be there and pointed towards replacing the gasket. Now that the gasket is replaced the amount of leakage is noticeably less. I'm just wondering if I should go back in and take the spark plugs out and wipe down or if it will just burn off or if the remainder of the oil will leak out as I ride. Or if I'm completely wrong and there is another possible issue?
Got delivery this morning, not an absolute gem , but as far as I concerned a cracker , get rid of those plastics (previous owner hit a pheasant), runs sweet as a nut , but will get to grips with the rest:D
So I picked up a 1997 Blade with 48k miles that has had a pretty hard life, looks like it’s been used for commuting year round but it runs and rides great so hopefully no gearbox/engine problems. I will use this thread to document my progress and post as many Pics as I can, everyone loves...
