marty, pistonguy, jaciche, grumpyunk, chewbaca, cyborg55 cyborg55 chewbaca grumpyunk jaciche marty pistonguy Hey everyone! So, I adjusted the chain and made sure it was all lined up (the 3 holes) along with the engine being TDC and it spins over now, sounds like its cranking but it also makes this awful grinding noise now, I have also adjusted my valves and found that one was loose as a goose and the other rock solid, I have adjusted them both to the width of a razor blade. I've checked for spark which I have got and I'm really getting confused of what to do next. I don't think It is the piston as since I have unjammed it all and put it all on correctly she moves easy as. The metal filings im pretty sure must of come from the chain as it is a bit scratched up in places but teeth still look okay!

marty, pistonguy, jaciche, grumpyunk, chewbaca Good evening all did alot of work on the scooter today and I believe I have found the source and a solid 80% of the way through fixing the old girl up I took off the following the cover over the cam shaft the two weird things (took a photo for reference and removed the two spacers) the cam shaft and then instantly saw an issue the chain was completely off and was jammed in the back, removed the cam shaft and then took that block off so I could see the piston. I have also discovered that when I got my oil change done by a friend of a friend he wayyyy over filled the oil and there was oil dripping in that thing. Im amazed the bikes done so many KM with so much oil in it holy moly. (Cam chain? it was running beside the piston and was causing the dreaded click...) Unjammed it and re-attached both ends and then tried turning the white fan that was on the right hand side of the bike if it was to be behind it and sure enough, piston moves very freely and fine now. The chain on the bike is a little bit scratched and loved looking and in one clip it has alot of damage as im assuming it was the clip that got jammed at 55kmh. It looks okay and teeth are okay and seems to work okay. I assume that the reason this chain came off was due to so much oil? Anyway, I have put some new oil in (correct amount and checked this time, put everything back together and it's moving now! It still isn't starting and I am now starting to suspect the Stator as it didn't look very good beside the white fan... I saw rust coming from it so I will replace that tomorrow and then hopefully it will fire up! Also my kick start still doesn't work? not to sure why, I've never had it working so i'm not to concerned.

chewbaca grumpyunk pistonguy jaciche Hey everyone Thank you first of all for all the replies As for the scooter... I drained all the oil and there is a mix of small 1mm long strands of metal and very very very fine powder looking metal in the oil. I put it all through the oil filter 3 times and in the end it only got the big (1mm) stuff, rest of it is so so so fine, finer than glitter. Im assuming im a bit up creek lol As im a complete noob to engines what has actually happened and what would you guys recommend I do next? Also will attempt to post pics of fragments i caught later.

I can freely spin the back wheel by turning the clutch assembly and when i remove the starter i can move the variator with a bit of effort, it doesn't really wanna do a full rotation though...

<<Sorry about posting in wrong section! very new>>
Hey guys and gals,
Very new to boards and forums and stuff so apologies if I've done this wrong and broken a few rules...
Here's my current situation:
I am 17 years old
I have a GY6 2007 Hanglong 50cc scooter (4 stroke)
It has a nice after market exhaust and sounds awesome, pretty bog standard apart from that.
I bought it at 3 thousand ish KM on the dial and It is now up to 5550km on the dial. I did an oil change at 4300ish km and put a new spark plug in 150km ago and a newer CDI at the same time (gave me 3 extra km/h oh yeahhh)
Everything was going awesome!
Until 6 days ago where I was riding along at 55km/h and all of a sudden the engine made a large growling sound and I lost all throttle, I flicked my indicator on, pulled over and the engine completely shut off. At the time I had assumed my belt was broken because when I went to try and start it after it had shut off it makes a single click.
long story short, walked and pushed it 6km home (holy moly that really sucked) and took the cover off, the belt was fine! I'm incredibly confused as of what to do next... She doesnt start and I really cant think of anything that would cause that loss of power and suddenly refusing to turn on! I love the dear little thing and it is alot of fun and having to walk places now sucks. I have seen conflicting statements online from broken starter / solonoid to water in my gas, any advice would be really really appreciated. I have tried the old CDI, new fuse, new coil and nothing at all. I've fully recharged my battery and nothing, still the damn dreaded click. Really really lost.
Please help the noob out! thank you!
