mysterious tank

Postby Wein6 » Fri Jun 20, 2014 4:15 pm



This seems like a silly question but I'm gonna ask anyway. I just got my first motorcycle and I'm checking out the whats what. I've identified my oil tank, my brake fluid oh and the gas tank. hehe. However inside where the gas tank is filled is a reservoir that looks like a radiator overflow. When I checked the fluid it was more of an oil and black at that. I couldn't find in my manual what this reservoir was. Can anyone enlighten me?

Oil tank.This isn't a Harley :lol: .The only oil should be in the engine,forks,rear shocks and final drive.As far as the yellow colored tank on the right side...it is a radiator overflow reserve tank.It should have antifreeze in it.

My oil tank is way up there? Then what is the dipstick in the lower left front? haha no not me :D . The two fluids (oils) are not the same color not even close. One looks like engine oil, the one on the dipstick, and the other looks like black crude oil. I'll post a pic or two later this morning. Oh and thank The Lord it isn't a Harley.

The upper tank,regardless of what's in it,should be the radiator overflow tank.
Some bikes did have a "dip stick" added to the front.Usually its level is checked through a site glass.

Okay I don't see sightglass only the dipstick for the oil.
Here I've posted the tank or the tank cover and the overflow radiator reservoir. I've dipped my finger inside and it looks and feels like oil however the label under the lid says anti-freeze and water 50-50 mixture.

The site glass.set the bike on the center stand.get on your knees and look at the engine in front of the foot rest.The site glass is about the size of a nickel with a flat head screw in the middle.Turn it,its a wiper.
As far as the oil in the overflow tank...we know that's not suppose to be there.
Bad head gasket or both seals bad in the water pump and the drain hole plugged.
Look under the front of the engine toward the left side.There is the drain hole.Maybe 3/16" .be certain its clear.

I found the plug to the water pump and checked the fluid, it is a clear bluish maybe a turquoise color. It looked pretty clean. There was a hole in the bottom of the pump. It seemed odd that there was no plug in it for me to unscrew. However I didn't feel any threads. I was able to stick a piece of wire inside the hole and clean out some road grime oil etc. I was very gentle as I did this and was able to get the wire maybe 2 inches inside the whole. Does this help explain anything?

As far as the sightglass it looks like the sightglass was converted to a dipstick. If that is possible.

No, the site glass is on the right side over the driver's foot peg. The dip stick tube is actually where the drain plug for the oil used to be. Check out the "How to" articles. The one showing how to change your oil shows how to do it with a dip stick there. Have fun with your new ride.

As thick as that fluid is on your finger it looks to me like some dipstick ;) maybe the p.o. added oil to the overflow tank. To be safe you need to flush your cooling system but I would remove and clean out the overflow before I flushed that oil into the system.

I'd run distilled water in it for a week or so, and then drain it, to see if the water ends up with oil in it, then if it's all good, then flush and fill with coolant. That way your not wasting coolant, and water is alot easier to dispose of then coolant.

Just my two cents, I'm sure others have differnt idea's, it's just what I would do.
