Hello I bought a 80cc/gy6 that had been upgraded from 50cc to 80cc by the seller Now I wanna change my jets (the main jet is 84 and the pilot jet nothing written on it) because I suspect the scooter is running lean can someone tell me what jet sizes should I buy or the standard jet sizes for 80cc Thank you  |

If you don't want to buy a set of feeler gauges cut a piece of a Soda Can or Beer Can around the center and use that as your feeler gauge, the thickness is about .003 inchs which is what you would want on a 50cc motor.   Alleyoop hhh sometimes i used razor blades it's about .004" i think . but it's risky can hurt the hands thank you for the trick |

Oh i forgot to mention that i had upgraded my scooter from 50cc to 80cc 1 month ago and have a distance of 200 km so all is new!
i use 15w-40 multigrad oil so i think it's fine
i don't know but a friend of mine told me that with air cooled engines always oil consumption is expected is that real and if yes with 0.75L of oil putted into my engine how much quantity must be the consumed normally after 1000 km ?

Hi
I have an air cooled gy6 80cc and I noticed after a valve clearance that there is an unusual oil consumption not so important but enough to make me worry about .clearly I haven’t a feeler gauge but I always used to adjust my valves without special tools letting them loose and it’s ok almost the time.
So my question is:” is there a relation between a wrong valve clearance and oil consumption and if yes how that can happens?”
to my knowledge oil consumption is due to 3 factors
-piston rings
-head gasket
-valve seals

Hello everybody here i want to ask some questions since i have bought an used chinese scooter(50cc/gy6) i'm new in this so plz help me handling somethings in this scooter 1)I have been always wondering what is the function of this bottle knowing that when i take a look inside it seem that there is a sponge?! i don't know were it was connected so if you have an idea plz tell me where to connect it?    2)the crank beather should i connect it to the "Air breather tube " or just leave it free.. i read some article where they wrote that in case the crank beather is connected to the air box it will throw oil wich will dirty the hole box so what is the solution in this situation?   |
