Assuming that the bike is otherwise running good and has no compression issues, it sounds like you mak have a clogged crankcase vent. If this hose gets pinched or clogged with mud, the crankcase will build up pressure and start forcing oil out whatever spot it can. If this isn't the issue, you will need to get a compression or leak down test.

Hi,I dont know what bike you are talking about,but it could be that the prockets are worn if it has a chain drive,or chain needs adjusting.

Yamaha zeal 1991 fuel and engine oil was leaking somewhere from the engine block... was flowing like a river out of the engine block.... i suspect the piston rings are shot but need a better opinion

If your rings were shot and the engine was running you would see billows of blue smoke coming out the pipes, as well as oil. If not running, then your fuel would end up in your sump inflating the amount of oil in there. (this does happen on all bikes only ridden around town, get it out on the highway to burn off the excess fuel then recheck your oil level.)
I'm wondering if you left your fuel tap on overnight (if it has one) if so, then you will have fuel running back out either the carbs or the boot that goes from the carb to the engine. Oil will leak if your valve seals are shot. it is possible that it was only fuel that was stained with a bit of oil.

Bar oil leaking after use

Release the chain brake, back off the chain adjustment screw several turns, then remove the side cover and the bar/chain. Clean the engine side case where the bar fits to and run the engine for a few moments--oil should ooze out of the side port in the engine. If ok, then clean the removed parts including the two small channels in the drive end of the bar that convey oil out to the chain groove on each side. Reassemble everything and then run the tip of the bar near some cardboard for several moments at speed--it should throw off a thin line of oil onto the board. Unless you have a leaking oil line or the tank is split, you should have minimal leaking problems. Hope this helps!

I want to resurrect my old bicycle (haven't ridden it for 10 years) and have found it in the shed. The chain is rusty and the tyres flat. Can I do anything about the rusty chain without having to replace...

1. buy a steel brush then brush out as much rust as you can from the chain.
2. soak the chain to used motor oil for at least 30 min.
3. then try brushing out more of the rust then apply "singer" all purpose oil to it...enjoy!!!

Oil leak

With a ten year old 250 cc engine that has been ridden a lot you should be prepared to rebuild the motor. If you have to have someone else do it the bike is probably not worth the cost. If you can do it yourself the parts can be bought for less than $400 and installed in a day.
