Help Identifying Oil Leaks

I am completely new at everything to do with motorcycles. I just bought a repair manual but I don't know what exactly the issue is here and what parts I need to work on. I am sure this seems like a basic issue, but I have been reading and getting to know my bike for the past three days instead of riding it and I feel like I have info overload.
Can anybody spell things out for me here? I would appreciate it. Kathy.

Welcome Scrappi! If I understand you correctly you are looking for info on oil leaks? You need to specify what year and what engine you are going to work on since there are many possibilities for remedies. If you haven't done so already, try searching the topic in the search box at the top left. Use the "forums" drop down menu to click on "knuckle busting" and then click on " the "engine, carb, fuel & exhaust" submenu. Then type in engine oil leaks. You should then get a whole bunch of threads on that general topic. There was a recent thread on oil leaks- here is a link. https://www.hondarebelforum.com/f76/...-new-post.html I just checked this link and it takes you to page two of the thread. Go up to the top and click on page 1 to get to the beginning of the discussion.

If that doesn't help maybe you can take a photo of the leak or area under the bike where the oil has pooled and post it. It has to be a jpeg file. Good luck!

Scrappi. I found a video on YouTube that may help you identify the problem better. Here is the link.

Some things are supposed to drain oily fluids. On the right side of the bike behind the engine is a collection of tubes. One of the two larger ones has a duck bill and may occasionally drip a little. The other larger one (puke tube) should have a plug in it and needs to be drained periodically. diagram here: https://www.hondarebelforum.com/f36/...ubes-9200.html

If there is no plug in the puke tube, and the leak you are seeing is beneath it, that may be the cause. That tube needs to be plugged to prevent unfiltered air from reaching the engine. If nothing at all comes out of the puke tube when drained, run something stiff up the tube. Some owners don't know to drain the tube, and I've seen one that formed a blockage in the tube.

The other, smaller, hoses in the cluster are gas drain/overflow tubes from the carb and tank vent. These should not leak unless there is a problem.

If the oil drain plug washer isn't making a good seal, that too can leak.

As stated by Nardospark, pictures would help a great deal.

Keepin' all the left over parts. Gonna use 'em to build another bike!

Where does the fluid that drains from this duck billed tube come from? In other words, what is its purpose?

I have noticed that mine will drip a single drop every now and then.

I think it drains any moisture/condensate that may develop inside the airbox.
