I have a 2009 Keeway Hurricane 50cc. Over the summer my scooter stopped running. (checked the spark plug, not it) Took it to the dealer and they fixed it and said that there was oil in the air filter. (and I did notice that every once in a while i would find a little puddle of oil under my scooter on the ground) And it had something to do with a part in the carbrater. When I asked the dealer if there was anything i can do to avoid it happening again. They said no. Just a month ago it happened again. But I don't have the money to pay the $200 to get it fixed. So does anyone know how I can fix this myself?

You might have a leak in your valve cover, going in your vent hose, need to replace valve cover gasket, Did the dealer tell you what it was before or could you ask him? You said it was going into part of the carb, I'm thinking could it be the reeds in your intake to carb?

Very simple fix, That is your valve cover Vent Hose. Take the hose coming from your Valve Cover going into the filter disconnect it from the Air Filter and Plug up the hole ON THE AIR FILTER. Then get a cheap FUEL FILTER and stick it on the end of the Valve Cover Vent Hose and tie it up high on anypart of the frame. Then Clean out your Air Filter which is full of oil and put the filter back on.
Make sure you are not overfilling it with OIL otherwise it will always blow out that VENT HOSE.

hello. I really have not worked on your scoot and was hoping one of the experts would pick up on your problems. But so far none I know have. So I will stick my nose in a little. for what it is worth. You may have more than one problem A 50CC is not good for much more than 25 MPH (true speed not indicated) for very long. 35 is about as fast as I would try to run most. As a result people tend to run near wide open.
That's pretty tough on any engine. It also increases "blow by" a lot. Blow by is the air/fuel/pressure that goes past the rings and piston down into the crankcase. There is really a large amount even on a new or rear new engine. The air has to escape out of the crankcase. On most late model scoots there is a system called "positive crankcase ventilation" (PVC) ( not 100% sure the order of the words but what is means is that the crankcase vapors (blow by) is feed into the intake system so that the fuel in it is burned and the vapors are allowed to escape into the exhaust system and in to the air. If that system gets plugged crankcase pressure builds up resulting in oil being forced up past the rings and into the combustion chamber and burnt. It also forces oil to leak past every seal in the engine.
so lets check that the PVC system is clean and working OK. First, check oil level. Is she full? Is it using oil?
Does it tend to smoke?
That oil drip is not typical. It suggests a problem more than a simple leak. Lets try to trace down where it is coming from. wipe off the engine as best you can and check again in a little while.
Do you know where the valves are? And the Valve cover? If not research for how to adjust valves and do that just to make sure you have decent valve clearance. ( A very common problem with China scoots.) When you find the valve cover . you will find a rubber tube running from the cover. Remove and clean it thoroughly.
Re the plug - how do you know it is oK? Was it wet? /with gas or oil? I like to have a spare plug so it is easy to replace a plug with one that I know is good. While it is out is a good time to check spart output to the plug. You should get a got 1/2" snap ( IN the shade) I stick a large nail in the spark plug boot in place of the plug and hold the boot so the wire is about 1/2" for the head while my lady hits the starter switch with the ignition on, brake on, and kick stand up.
Now let us know what you find.
Good luck.

Well I am an expert, that is why I chimed in since the respones where way out of line. And like I said it is a very simple fix, those monkey machanics all they did is clean out your Air Filter and charged you a lot of money for a 10 minute job. I am an expert on the Motors,Carbs,Trannies and CVTs I am not an expert on Electricals but the scoots are easy to test and figure out what part is not functioning correctly. The scoots are really a no brainer they are bascially a Lawnmover engine with two wheels.
Just make sure the Valve cover Vent Hose is NOT KINKED or BENT in any way It MUST BE ABLE TO VENT.
What would help would be to take pictures of the Carb area and hoses as well as the valve cover. Knowing the type of Carb that is on there is very important.

Look, all of yall are talking about valves covers, vent tubes, and oil.
WELL, If im not mistaken, the 2009 Keeway hurricane 50cc scooter is a 2 STROKE, which does not have valves, vent tubes, or crankcase oil.
Richardthescooter1 doesnt know what the hell hes talking about he thinks an engine has valves AND reeds HAHAHA
Well first off start by cleaning your air filter out and airbox, it could be suffocating the engine, if its a foam filter and not a paper filter you can just clean it with water and soap and let it dry out.
How did you check the spark plug? Did you put it in the cap and kick the engine over with it grounded to the frame to see if it has a good spark?
Maybe your oil pump is pumping too much oil to the carburetor.
But honestly i dont think the oil in the airfilter is your problem, all of mine do and its not a problem i just keep the filter clean.

Hi Guys   Got to agree with mechaniczman, your all way off the mark as it is a 2t engine not a 4 www.keeway-america.com/product/hurricane.htmlTake care and drive safely dear friend Yours Hank |

Then this should be moved to the 2T section. But if 2T and its is getting oil sucked back into the Air Filter and its a lot then there is a problem with the Oil feed system. Now some have a double cable on the throttle that allows so much oil to drip into the Fuel as it is being sucked into the intake and it may be pulling to much which can be adjusted. Others have a automatic Drip system and yet others have the drip system but have a screw to adjust the amount of drops being let in.
All in all Pictures would be worth a thousand words of the Carb and cables if we do not know what type of system is on that puppy we are all guessing on how to fix it.

i usaualy do not post do to others but i have a 50cc keeway scooter and every once in a while my air filter will fill with 2 stroke oil and then leak all over the place, making it hard to start and when it does smoke like pest control, my dealer said it was a common problem with a replacement part know as the oil check vavle which keeps the oil from flowing when the motor is not running, i talked to the mechanic and he told me he has seen this alot on the hurricane.

Sorry Princess
Sort of funny ain't it? Maybe a lesson for all of us. In our efforts to be helpfull we probably confused the h--- out of the princess.
The real question is did you get it fixed? always remind us what engine you have. simple little note 50CC 2t tells us a lot.

Ive just had the exact same problem with my hurricane. The problem was i was putting too much oil in simple as that. I took out the extra oil, cleaned the air filter (it was dripping with oil)) and now it works like a dream.
