i should be sleeping but i can't stop thinking about my scooter. fixed a small oil leak over the weekend and the first thing i noticed when i removed the valve cover was the lack of oil on the chain and rocker arms. lately i been a little concerned about all the small fragments of permatex ultra black i haven't been able to remove from my engine.
then i also thought, well, maybe the oil drained since i haven't started in a day. put everything back together, took a break then rode 3 miles to the store. when i got home my engine was extremely hot. the vent in the plastic near the valve cover was as hot as my exhaust (or near).
so now i'm concerned i ruined my engine with permatex ultra black. been researching something that will dissolve and found threads on flushing engine with diesel. now i realize it will eat away at all the seals and could risk more damage but at this point i don't think i have any other alternative. i just don't want to start a fire so i'd like to hear how you do it. thanks.

I put a new belt, new clutch, new clutch bell, new variator and put the stock rollers back on; it improved a bit, but moves painfully slow even at WOT. I give up, I don't know what else to do, it makes no sense.  i would try rotating the clutch bell by hand, see if the tire moves and if you feel any resistance. as geh pointed out might be a problem with final gears. |

just spent an hour of my time at the post office trying to track down my scooter parts. i will pay extra for signature or i won't order from now on. an extra $2.  could have saved me this headache. Are you sure it is the post office and not UPS, Fedex or some other shipper that claims to have delivered your parts? yeah it was usps. surprisingly it arrived that afternoon with the paperwork i filled out in the morning. guess that hour trip wasn't wasted after all. new rings, gaskets, cam and rockers all installed and running great. well gr8 for a chinese scoot with 16,300km |

Well it's a good thing it didn't electric start, imo. With a 50mm and no base gasket, your engine probably would have been toast in about 500 miles, lol. So consider it a blessing. The compression reading on that thing would have to be dangerously high. guess i been doing it wrong. are all base gaskets the same? the two i have installed were paper thin. |

On the center stand, dipstick NOT screwed in, full reading to the top of the hashed segment. not screwed in should read about half way up the hashed segment. i would say you're about 100ml over (maybe 200). 100ml over proly won't be a problem until you hit WOT. i have accidentally over filled once and oil did spew out of my engine too. i meant to type 100ml over probably won't cause problems but 200ml over would likely cause problems at WOT. |

They sell an oil radiator cooling unit for 50cc-150cc GY6 scooters. Yeah , we know , lol . I just like to think of other ways to cool these things , lol. if i was going to do anything other than buying a bolt on water cooled engine then i'd cut vents in the plastic. add a couple hoses and connect to the air box (edit: oops, meant cooling shroud. forgive me, its late)  and/or direct to the valve cover. only problem i can see with that idea is at idle. idk if it would raise the temp at idle. it would certainly lower it at WOT. |

ok, so you didn't need to split the case? was your starter still working? just curios of your symptoms besides the noise at idle. What is Moise ? lol, you typed that and i figured "noise". i'm a fraction smarter than a monkey. |

apparently nobody here has an answer. if haven't figured it out by now i would try calling your supplier. occasionally you'll get a knowledgeable employee. if scooter elements was still around he would have info and parts for you.
what happen to him?

Wouldn't the timing go way off, and it wouldn't run right if the flywheel were spinning? My woodruff key just broke, and it wouldn't run. that would be my thought. if it ran at all it would run rough. |

as long as you didn't block oil passage then i think you are fine without a base gasket. it shouldn't effect the starter anyway. did you make sure the piston isn't hitting valves? can you rotate the engine by hand?
it could be any number of possibility's. for months i would occasionally have symptoms of a weak battery. i tried to diagnose but finally gave up. it still started so i figured why frustrate myself with this problem. then i replaced a camshaft with worn out bearings and it solved my slow (sometimes click) starts.

I bought an ncy high performance starter clutch . I think I paid around 50 bucks . TBA I can't remember . it was between 40-60 bucks, lol . you will also need a side cover gasket . other than that its just the right tools . you need a flywheel puller and a starter nut socket. Its a special type of socket. I didn't have one , so I held the variator nut and Grabbed the clutch but with vise grips and used a breaker bar on the end of the vice grips. ok, so you didn't need to split the case? was your starter still working? just curios of your symptoms besides the noise at idle. |

lol, i was about to ask if it was the faint rattle or the loud erratic rattle until you started beating the scoop.  i think it is the same sound but i'm not 100% certain. what did you order and how much was involved to install? |

hmmm, just now thought about the new rocker arms i installed yesterday. the pins and arms were a loose fit. think the diameter of the pins were a bit too small so it might be the rocker arms/pins i'm hearing. i don't know, i'll have to listen close and find out where it's rattling.

gearbox gasket  i've never replaced one so not sure if it's as easy as removing the gear cover but would assume. Wonder if that has something to do with the belt not climbing at all on the variator issue I posted on the other thread  if oil got on the belt then it would certainly cause problems. i would think the variator and clutch would function (well oil on the pads would cause problems) but a slippery belt wouldn't move much. |
