Hello,
I bought a 2003 Derbi Boulevard 150 recently, and out of nowhere it began dripping oil. Here's a video showing the issue.
I'm not sure what part the oil is dripping from; I was having trouble identifying it in the manual. Do you guys have any idea what part this is, and if the seal extruding is in fact the leak reason. If so, I'm not sure how the seal got there, or why it started leaking now. If I need to take the piece apart, can you link me to a good discussion of how it can be done?
Derbi is a European bike, not Chinese. It has a Piaggo (Vespa) ET4 Engine, if it matters.
Thanks!
Caleb

Yes that is oil and it is most likely coming from the Valve Cover Vent hose which they usually attach to the Air Tubing going to the Air Filter. That black box contains your Air Filter and I would imagine it is now full of oil. It may be that it was overfilled with oil and the excess is being blown out the VENT hose and into the air box.
So take the Air Box cover off and clean out the air filter being clogged with oil will make the motor run rich not enough air PLUS the Vent hose from the valve cover needs to Vent and if the Air Filter is clogged already with oil it is not venting and more oil will get squirted out

Thanks for the help. I'll go give that a try now.
Relating to the Derbi brand, I was sold the scooter under the impression that it was a quality European brand, under Piaggio. But I just talked with a mechanic and it seems that Piaggio, Vespa, and in turn Derbi are now produced in China. Unrelated to this oil leak, is Derbi reputable in anyone's opinion? What are your guys thoughts?

Here's an update.
As explained in the video, I did what you said, and you were right. I couple ounces of oil were absorbed into the bottom of the air filter. I was doing some test riding and my bike did tip over about a week ago. I imagine this could of been the catalyst for the awry oil, and given a weeks time it finally found it's build up in the air filter. Should it be safe to assume after adding more oil that this doesn't need to be addressed further, or could this mean something is more seriously in need of fixing?
Thanks again for the help.

Yes the tip over could of caused that so I would just watch it and don't overfill the oil in the crankcase. The Filter wash it with your kitchen dishwater soap let it dry and put it back on.

It's usually the companies that start in china and produce copies of other products that are not of the best quality . ". Usually " |

howdy and welcome to this forum. as alluded to above, the actual quality of the materials and procedures is governed by the quality control department of the parent company, in this case possibly piaggio. all the products i have seen from them are relatively good quality and assembly.
lotsa miles and smiles to ya
