i torqued to 19 ft lb. and none of the threads were stripped inside or out of case, studs, or nuts. there was just one stud that doesnt get the pressure required to click my torqe wrench, i think its just stretching the stud to the point where its about to break so i ordered more. but im more worried about why the damage is being done to my jug and piston and whats causing it, do you think its the one stud not being tight enough? it still gets tight, probly about 15 ft lbs but not where it should be ya I think thats it. its not just torque but if the stud is weakened from stretching its not going to hold right |

OK so i found the dealer I bought from did do PDI, but their PDI includes lights, checking gauges and other electronics, check battery, do an oil change and start the bike to see if it runs. they did not take the scooter out of the crate just make sure its good to ship. i think they did start it b/c some of the plastic sheeting was melted by the exhaust.
so ya I write it up to a learning experience for me
i found one more thing, the rear fender was missing 2 of the 3 bolts

stripped nut/threads/studs could be why it doesnt torque did you replace studs and nuts, check for bad threads in engine case?

Sounds like i should get a new carb anyway, if i mess it up i don't want to be without a scooter until a new carb comes in the mail.
i do want to get it open though, at least to see what jetting it has, i hear they make these scoots a bit lean from the factory, so if this is correct then get the next size up.
are there any surprises inside the carb like pressed in jets?

as i understand, the float is suppose to maintain the fuel level not drain and refill the bowl. if the fuel level in the bowl goes down too much you could get bogging even if there is still fuel in there. some suggested the vaccum problem on my thread and suggested a better vacuum pump or an electric pump. im not sure if vacuum is my problem or some thing else. but i found a thread with links for a better vacuum pump and an electric pump for sale both cheap. scootdawg.proboards.com/thread/21099/electric-fuel-pump-install-video |

i am thinking of a new carb, i discovred the one on there has no mixture screw and has these brass plugs instead of screws on the float bowl, never seen anything like it.

you can try shock extenders, common item at auto parts store for lifted trucks, not too expensive either. they will lift the rear of your scoot a little though.
also are the shocks mounts the same top to bottom, if so you might be able to mount upside down.
some shocks you mount upside down, some you cant.

PDI was suppose to be a part of the dealers service before the shipped it to me. they said they also change the oil. so maybe i was ignorant that they would check those basic things. so when i started finding things wrong i immediately change oil, if they didnt actually do pdi then they probably did not change oil. so part of my mistake was trusting the dealer
so i may of went 70 km with the crappy fish oil or what ever the chinese put in there, hope that did not damage anything

1 or 2 minor flaws.. Okav those kids in china are probably exhausted and over worked. But you just plain need to take it back and get an other or go to another dealer.. Somethigns its like ok its irritating, it sounds like they didn't even care when they put it together. Imagine what other problems are lying to surface that you can't see. ya thats why i made this thread, gives us ideas what to check. i did expect the bike would not be perfect but its worse than i thought. Yeah i would take it back but the dealer is in another state i had the bike shipped to me. i do customer service as part of my job and i am thinkign if I was the dealer, i dont know what could they do for me, except send parts or some thing. id have to pay hundreds of dollars to ship it back i do have a warranty still so last resort if the engine siezes or the frame breaks in half i hav recourse. i may just sell it and cut my loss, get some thing else, i saw a scooter i liked a lot the other day |

i hope i solved it, scoot did not do it today. rode it hard today. though it was  yesterday and scoot was idling in traffic for a while and it probably got a lot hotter, today no traffic and 75F on same route. but no problems at all. as for the vaccum problem i wonder if this would work, there are small vacuum reservoirs in the HELP! section of auto parts stores, throw one on with a check valve. seems so obvious, i have to wonder if the scoots already have them? |

Hey, I didn't see another thread on this so i'll make my own. What flaws did your scooter have from the factory. Might help me and others know what to check on our scoots and what too look for when buying a new chinese scooter. Mine is a 2013 Jonway 150cc, this is what i found so far (100 km on bike), bet i will find more - Stem nut dangerously loose
- brake rotor bolts hand tight about to fall off
- fuel line hose clamp on middle of hose instead of end
- CDI just dangling above engine from it's wires, not in it's mount
- rear brake non functional
- brake handles stick
- flaky headlight beam switch (some times headlight shuts off)
what about you?

well actually they make 50cc and 150cc version of this scoot. so apparently there are bargain 50cc scoots out there with bad frames?
i found others with the same model of scoot, thought of trying to contact them. I think i need to sit on another chinese scoot and get a feel for what it should be like.

Hey, the scoot did it again, have more info
this time it did not start (except with starter fluid) not even hours later, meaning its a fuel problem. i thought it was the fuel pump so i looked at the lines, i found that the hose clamp that was suppose to be on the end was on the middle of the line between pump and carb. I didnt think anything of the clamp in the wrong place so i pulled off the line to test the pump, and cranked the scoot, fuel shot out of the pump. i put the line back on correctly and she fired up.
so whats going on here. would the clamp really pinch off the line to the point it would not run at all?
or did running the pump without the hose on it blow out some crap, trapped air or something and make it work again?
Want to get to the bottom of this, so it wont happen again.

Are you sure its the frame and its not your front shocks that are weak and you think the frame is flexing but its the front going down when you put your weight on it. Alleyoop pretty sure, i look at the frame below the seat and that part stays fixed while the rest of the frame is gradually bent more and more (largest flex was the stem tube area) i think the frame is mild steel which can flex a lot without losing strength trying not to worry about it, i might not have noticed at all if the stem nut was not loose in the first place |

just curios, are the turn signal relays the same as in cars. i got a really noisy one in my car and would rather have the car silent than the scoot as i some times forget to turn off signals on the scoot

yesterday and scoot was idling in traffic for a while and it probably got a lot hotter, today no traffic and 75F on same route. but no problems at all.
