Bare in mind I am not a mechanic, I just happen to be driving these things for about a decade now.. So I know some things..

Try priming it while it's running, by default you should hear the idle pickup if you have a nice prime pulse going on. if it's practically an instant cut off there's to much gas going on.. But..

Sounds like your bike might be getting to much air. Or not enough. Is the air filter 100 percent on? any cracks in the plastic anything? missing parts? If any of this has happened you might have collected sand debris to much more inside of your engine, but of course this would take a serious long time to notice any issues.

As a simple check, check your gas lines for any cracks, it has been really cold lately. if you still have the stock gas lines I'm sure there are some cracks somewhere. If so if you are lucky they will be at the ends and you will have enough space to cut it right at the crack and get bye for now. If there are any cracks you would be taking in more air with a burrn sound typically when you hit the throttle. Or just near impossible starts...

My bike did this recently, cracked fuel filter, when I started it, it smoked so I knew there was something not burning right lol, of course that motor is dead now..

Keep an eye on that fuel filter as well, that thing could have a hidden crack somewhere.

Another thing is.. Have you messed with the idle mixture screw lately? That might need to be adjusted.

It was 22 degrees this morning, these scooters do not work to well in the cold..

Any way you could help me out?

Highly appreciate it if you can in some fashion.



I have money

Well I have a 2008 Vip based model 50cc scooter. The scooter engine it self had a hard long life, Managed to get to 38,000 miles on the thing and two days ago when I started it, it almost sounded like warshers pinging around on the inside of the engine, I already knew right then I was going to be breaking down, made it to the grocery store by time I made it back out to the scooter it sounded like the iner parts of the engine just shattered on starting.

Out of ego, I started it one more time, terrible idle, instant cut off and it almost sounded like a chain started smacking around on the inside when it shut off, I went to start it again xD and there was no air coming from the exhaust port, rpm gauge never moved..

The engine it self in al honesty had a very long life span for being a Chinese scooter. There are no mechanics near me what so ever, there is a vespa shop 50 miles from me and they stated "We do not work on Chinese". I have no way of getting it anywhere and for the sake of my pocket I think it would be cheaper just to order a complete engine?


I should be getting my license soon. So even replacing the engine would help me make it a better bike for a re sell. maybe even a resell for the same amount I payed for the engine lol..Might be better off buying a new speedometer and gear puck while I am at it while the miles those two devices have on them. 

Can anyone help me lol? 
I found this on parts for scooters, not bad.. Really curious if there is something better, or more user friendly to install..
www.partsforscooters.com/Engine_longcase_4-stroke_qmb139?sc=34&category=133360 Maybe even bith a bigger bore or something?


* I do not have a stock muffler.. Mines load, it could cause damage on a new break in?

From a long time ago.. 

Any help is highly appreciated, don't want to get fired for having an unreliable ride

czmdiver All restore really does is re adds compression to engines that have very bad or any scoring what so ever, causing loss in power to much more, I don't really see why not. I've considered on becoming a victim to it, Either it will work fantastic and I will re gain speeds. Or something else..

I wont be driving my current scooter somewhere in 4-5 months as I just got a car and I would prefer to just buy a new one as a play toy any who sometime.

Yeah I was told that 10 extra inches shouldn't hurt

Yeah, I was mentioned that regardless even ten inches shouldn't hurt me. the length of the rear wheel to the front is 6 foot that's only 8 inches longer than the bike. that gives me a lot of room to rout the cable.

I was also told a 50cc scooter that's 6 foot long with dual rear shocks is very unusual.. Said something like the 150cc scooters are like that.

---

I called a place near me that's a 15 to 24 minute trip only to them and they wanted to charge me 35 for just the cable...

Called a warehouse 30 miles out, these guys are actual dealers, As well believe it or not there Chinese and cant really speak English to well, they told me 30..

At that point I said okay... Well instead of paying 30 what can I find that I could basically get the same day...

That's when I found that kit for 15 dollars. + 9 dollars for shipping 'To get it the same day. Either the rest of it will turn into junk or it will be nice!!

Figured why not go all out in that department of parts, just bought a new carb anyway..

I sadly can not accept your extremely very kind offer, As it's not something I worked hard for.

While money is tough, I will eventually get around to it, Maybe even a 100cc kit.
