139qmb stater noise  By  workdog95 (Read 1,918 times)

Not yet, only thing Ive done to it was take of the rear rack, change the oil, and adjust the idle screw. ill try adjusting the valves tomorrow morning (had the thing running for the last 45 min). Im thinking its the bendix.

It has sat for a while (atleast 5 months). Kill switch is on, It will run if I kick start it. But its a dog. I can get it to go WOT, back it down, let it sit for 1-2 seconds, then twist the throttle all the way and it dose nothing!

Thanks for the reply!

Mine is doing the same thing. I commented on your youtube link workdog95. I have to kick start it to get it to start, however... if I have been riding it, then get off it and run an errand where I leave it sitting for about 10-30 min then try the auto start button, NO problem. Only when its not SUPER warmed up does mine make that same exact noise. Today it started giving me a lil crap when I accelerated. Mine is a cheap but new chinese scooter, 6 mo old with 1,800 miles on it. I have had 2 oil changes and the spark replaced but never had the carb cleaned or valves adjusted as suggested by now. Battery was tested as normal. Is it hard to find/check/adjust the bendix, bushings, solenoid and adjust the valves? Im a chick so im not great w this stuff. I have changed the solenoid on my car but not sure where it is on the scooter. I saw a great video today on how to clean the carb but Im afraid that Im not going to be able to get it back together once i take it apart I drive my scooter every day, unlike yours workdog, mine has not sat at all. One thing I did totally mess up and im wondering if this has anything to do with the problem or may cause problems in the future. I did add oil to it (the full synthetic kind) thinking i was doing something good for my scooter then learned you cant mix that w regular/cheap motor oil. I went to the dealership and asked if they used regular and after they said yes and drove it for about 15 min total I had them drain all the oil and put in all synthetic so the oil was no longer mixed. I know i really should do my own oil changes too. NOW i learned that u shouldnt use synthetic oil in a scooter. Also I had them put in 10w -40 and i hear u are only supposed to use 10w 30. Not sure if the 40 vs 30 makes a difference. I live in South Beach where its hot, not sure if that makes a dif what kind of oil i use either. I paid $1,000 new for this scooter so i almost want to run it into the ground and not put a lot of money into it and just buy another one in 6 mo since i think i already messed this one up. I guess ur first scooter is like ur first car (that you make mistakes with)

Cool. Ya I didn't start him on the full synthetic oil until he was at about 1,300 miles or so. It does the same exact noise, (tries to turn over then hisssss) just like the link workdog 95 posted that started this thread off (the only time it doesn't do this is when it is VERY warmed up) like I have driven it within the past 30 min. Starts no problem then. If it has been more than that it gives me issues and I dont even try to start it w the button cuz it sounds like its going to drain the battery, I just kick start it when its not very warmed up. The lagging was a new symptom today but only happened for about 5 minutes, before and after that when I was driving it was fine.

Sounds like your starter is about done...probably needs new brushes or a rebuild/replacement.

Get a bigger battery with more amp hours (AH) You can pick-up a lead acid with 25 AH for like $35 buck at Walmart on sale. They are used for Skidoos or Riding Mowers. Just put them under the seat and extend the battery leads.

Difference of day and night from the tiny chinese battery...

You could also have a charging issue. You should check the DC voltage coming to the battery. It should be 13.5+ volts. Lower than that you have a rectifier/regulator (R/R) problem most likely...

Scooter don't use the battery to start with a kickstart. This means you stator is probably OK.

Could be a bad battery or perhaps the charging system isn't work properly...

Also your valve gaps probably need to be adjusted. They should have been done at about 1200 miles.

Not the same issue, but they need doing soon...
