I have a 2010 Speedster (handsome boy style) GY6 150cc scooter. It has 540 miles on it. I have an oil issue BAD, When I ride for a long period of time and stop I have oil blown from the starter to the back of the scooter, it goes all over the fender, the muffler and air box, it has leaked to the point were it drips off the bottom of the CVT cover.
I have removed the tube from the valve cover and the inside of the hose is clean, so I do not think that its from blow by, but my airbox and filter inside is soaked in oil. Is it possible that the oil is coming from the carburetor instead? And it leaks no matter what the oil level in the engine is or what thickness of oil I use. And its done this since it arrived at my house from the dealer.
Any help would be appreciated Thanks!

The oil is coming from the starter motor where it mounts into the case. There is or should be an O-ring in there. I have seen them broken or missing totally. Check that first. You can often get new O-rings at plumber's supplies...
If your valve cover hose is attached to the air box, then unfasten it there and stick it into a catch can. Sometimes the air boxes are not injection moulded correctly and in fact the entrance to the air box is blocked...
Try that and see if it makes a difference on the oil problem

OK, assuming that my O-ring is gone, do you know the approximate size it will take to fix it? Or is it something I will have to take the starter off and take to the store with me?
And this oil issue doesnt happen crusing around town, but when I hit top speed for an extended time thats when it starts leaking/blowing out pretty bad, in a 50 mile ride last week I went through about half a quart of oil. When I ride at full speed once I stop it will be dripping, its gotten so bad that the belt slips, so I think its seeping through the CVT cover inside..
I purchased an oil catch can and PCV valve through SCRAPPYDOGSCOOTERS.COM, I hope it will work, the clamps that came with it arent good, they all stripped.
I'm going to install that catch can and then take off my airbox and JB weld the hole up in the box. When I first got the scooter it had a clear tube coming off of the airbox, well that filled up in the first 30 miles and then it started dripping from the airbox..
Is is possble for the oil to be coming from the carburetor?

First make sure the hose coming off the VALVE COVER is NOT BLOCKED or KINKED. It has to be open to Vent pressure from the Crankcase. If the hose that fills up is connected to the Valve cover that is the Valve cover vent hose. And if its throwing that much oil make you do not overfill the it with oil. on the centerstand when you unscrew the Oil Dipstick clean it off and then just stick it back in but do not screw it on. Then take it out the oil level should be half way up the full mark. If you overfill them they create to much pressure and blow the stuff out.

I have a question on the valve cover to airbox hose connection.
When I open up the airbox, and inspect the hole through the airbox that is connected to the hose, the hole is only the diameter of a needle width, not the diameter of the 1/4" ID hose or hose connector. Same for the size of the hole for the clear plastic hose for the drain. I would think that this hole should be a full 1/4 diameter. Is it possible that it was not drilled our correctly at the factory, or should it be a very small diameter (perhaps a few thousandths of an inch) ?

It should be open more... this is what I was referring to in a previous post. These are problems with the making of the air box.
Drill it out to 1/8" at least...

The hose from my valve cover wasnt blocked at all or kinked, I looked at the airbox and the hole were the hose from the valve cover connected is open as wide as the connector.
I hope I have solved my issue with that oil catch canister, I have it installed, we just arent having good riding weather here, so I wont be able to test it out till later in the week.
Is JB weld a good choice when it comes to blocking off the two open holes I have in my air box now? One hole was from the hose off the valve cover and the other hole is were the drip tube hung down, the connector broke during shipping.

You have to figure out the exact source of the leak......and it's not coming out of the carb. For testing....you can run a line from the valve cover vent port to the very rear of the scoot. Just let it hang down....any fumes blown out won't get on the scoot.
The problem with finding oil leaks......they could start at the front of the engine, and end up dripping out the rear.
Possible (known/common) oil leak spots....
Valve cover gasket.
Starter "O" ring.
Crank seals.
Cam chain tensioner gasket.
Etc.
Clean everything off, fill it to the proper level (it only holds 800cc), park it over a bunch of paper, and run it till you see drips. Follow the drips back to the point of origin.

Sure JB weld, or just put a piece of duct tape over the holes in the inside of the air box...that way you can put it back 'stock' should you need to...

Bluefront> I have it back togther now and Its all cleaned off, the first non-rainy day I get I am going to go for a ride and see if it leaks anymore, if I still get oil (which I doubt I will) then I will have to check the seals you were talking about, I know the valve cover isnt leaking or the cam tensioner seal, the top of the engine from the carb/starter area up to the front is perfectly clean.
I just bought this scooter february 25th I had it shipped to me from EVOSCOOTERS.COM by ESTES EXPRESS company, and I have had nothing but problems with it.
When it came to me it wouldnt start, I had to replace the coil and CDI, both were no good, I had a bad battery shipped to me, the seller shipped me a new battery with no acid or caps. My scoot was damaged in shipment, they only replaced two of the 5 damaged pieces. So if anyone out there is planning on purchasing a scooter from EVOSALES.COM, DONT DO IT! Their prices are reasonable but their quality sucks!

Sproket> yea I learned my lesson to online buying, NEVER again! This has been the worse experience of my life! And the worst part about it is, the seller wouldnt even honor his return policy on the webpage. The day it arrived I called them to tell them it was damaged in shipment and I didnt want it, they said "oh well will take care of everything for you, we promise" thats what the 7 percent labor allowance was for, to take care of EVERYTHING...yeah right, labor is about $65 an hour.

I noticed that my article was posted on Scam Informer, thats totally crazy! I originally posted that entire thing on http://www.ripoffreport.com....So they must be putting it out all over the net. I hope I put those people out of business I really do.

When I installed a BBK on my 50cc GY6, I immediately noticed an oil leak......which was difficult to pin-point. But since it had never leaked before I figured it had something to do with the kit. It turned out to be from the new cylinder base gasket, and was completely hidden from view by the engine shrouds. My 150 GY6 has a minor leak from the left side crank seal.....ends up dripping out the very rear of the CVT cover. Tricky things....these oil leaks.  |

I installed that kit I ordered from scrappydogscooters, the oil catch canister.... Well, its not leaking at any of the connections, but now its blowing oil out of the PCV valve end on the canister.... Has anyone else installed one of these canister kits? I think they are a good idea, but the canister could use 1/4" inch outlets instead of 3/8" and they could have included better clamps, all mine broke when they got tight.  I installed it by placing the tube going to the valve cover and the tube going back to the dipstick on one end of it, then the other end has a 2ft long tube going to the pcv valve. Only thing I can think is my canister is installed almost laying flat. Would it help if the canister was completely upright? Any help would be appreciated at this point.. |

Disconnect the end that goes to the dip stick and use the standard stick. If the valve cover vent is open then you only need that one.
Check the oil screen.. If it is pushing that much oil you have something else happening somewhere.
Possibly valves or rings...

I've installed a Scrappy catch-can setup...... Link. In my setup the thing is mounted almost level like yours, but all that comes out is fumes. You've got other problems..... |

You're right I DO have other problems......  I saw your posts via the link, I set mine up exactly were you did, between the frame and the outer plastic on the right side (mine is the handsome boy design with 2 lights), I also had to use a reducer and 1/4 inch hose (I wonder why they didn't design the canister with 1/4 inch outlets instead of 3/8? I also bought new screw style clamps, all mine that came with it stripped, and the quality of that kit overall in my opinion IS NOT WORTH $29.95. At first my canister was setting level, after still blowing oil out, I went back through and mounted it straight up and down, I then took the PCV valve and ran a tube so it stuck out in the air behind my seat. Well after a test ride at full throttle for about 2 minutes it started blowing oil out STILL..... So Monday this scoot is going to a repair shop...If they want an arm and a leg to fix it I'm just gonna buy the whole engine/transmission from Scrappy for $375, I can swap em out myself in about 3 hours or less. |

I think you could install a quality top end kit faster and cheaper still. Also if you question scrappy's product and business, and then you state you are going to buy a complete engine from him in the same post? I don't get it. Good luck.

I modified my previous post. I don't have a problem with Scrappy's, I've used them in the past and got parts from them with no problems, this part inparticular just doesn't help my issue, and thats not their fault.

I can get a piston/ring kit from Scrappy for 29.95 with shipping, the shop says it will take 4 hours to fix, at $65 an hour so all together thats $290 bucks....It would almost be better to buy the entire engine for $375 and have some spare parts.
Does 4 hours sound right just to change the piston and rings??? It seems a little long to me but I dont know that much about these engines.

Thanks everyone here for the help, I ended up getting rid of my problem POS. It was blowing out so much oil it was like I had the dipstick out and I dont know how it stayed running....
This isnt the first one of these 150cc handsome boy style scooters I've seen like this...my friend just bought one and the clear tube has filled up with oil and its got 100 miles on it, I told him, you better get rid of it now while you can my friend.. I even offered to sell him a copy of a GY6 shop manual.
