Chinascooter

I have a friend that was involved in buying scooters from China,when you told them what you wanted you were asked to specify what price range you were looking at.
Thus if you specified $5 quality level that is what they would supply and if you wanted a $20 quality level that was fine too.
Surprise,surprise you get what you pay for.
Seems like such a waste of resources to make crap that wont even operate for a 100 hours though.

 

It does, but as long as there are people willing to buy into $5 quality scooters ( :? ) they'll fill that gap in the market...

JPaganel, sorry for turning the thread into a debate :lol: I forget now if this is 2 or 4 stroke?

Just trying to find details on the Vino to compare it to the Aerox but can't find it :?

 

Vinos came both in 2 and 4. This is a 2.

 

Siliconed up the intake, put it back together, and couldn't get it started.

The petchicken is bad. It leaks fuel out the vacuum side and does not have fuel coming out of the fuel side.

 

Wring it's neck

 

Alrighty, then. Moving on.

Siliconed up the intake. Finally got a new fuel valve. Put it in.

Now, I can start it, but to keep running it needs to have the throttle cracked open a hair. Let go of the handle, and it slows down until complete stop. At part throttle it runs strong.

Wonder if it was adjusted for the air leak, and now that it's no more it doesn't have enough air to run...

 

Found the idle screw, got it set to where it idles and doesn't die.

Actually went a whole block on it. And back.

The thing won't go over 10 Mph. As soon as you crack it open more, it bogs down.

Main jet clogged?

 

Did you feed the chicken?

 

Sacrificed it and got a new one.

 

Possibly, be worth making sure the carb goes to church (at least there's only one of them this time!) and that the float height is in spec (whatever it is :/ )

CV diaphragm not split or piston not rising properly? Umm, fuel definitely getting from tank to carb properly & no air leaks now? About all it could be on the fuel side (unless the main jet was never drilled big enough).

EDIT-: perhaps another run & doing a plug chop after holding it wide open (or to max speed & where it's just starting to bog out) for a few seconds would tell you for sure it's fuelling related

EDIT2-: Also, just for shits & giggles, perhaps you could find specs for oil flow rate as it's pump lubed (probably only worth looking into if it smokes even when warm though as it'd probably show other symptoms if it were this) and maybe even find a way to check the crank seals (if you can access the crank ends you 'd probably see oil/fuel mist around the outer part if they were bad, again not as likely as I'd expect it to be more a tickover issue, but worth checking all the same)

If it's not fuel/mixture related I suppose it could be timing, perhaps not advancing as it should or set up for low octane 3rd world fuel but I'd still make sure the mixture's sorted before suspecting ignition trouble.

Oh, and did you fry up the old petrooster to the Colonel's secret recipe? lol

 

I've had the carb open, there is no gunk there and the one jet I saw was clean. Probably worth checking again.

Float is plastic and not adjustable - molded in one piece.

No diaphragm. This is a round slide carb, slide is pulled by cable directly.

Worth a try.

Specs? Bwahahaha! You Brits and your comedy...

I could look up the Yamaha that I think this is copied from, but whether that's actually in any way relevant is anybody's guess.

Don't really know how the timing works on little two-strokes.

Nope, just wrung it's neck. Did give some thought to shooting it, but my shooting club does not allow junk targets.

 

Figured it out.

I forgot to put a restrictor tube back in when I was reassembling the airbox. It makes the air inlet about the size of a BIC pen.

Running without it lets too much air in (pods, anyone?) and makes it die from too lean a mixture.

Now it runs, still smokes a bit, but actually goes. I went to the gas (petrol for you, bloke) station and back. According to it's speedometer it reached 40 Mph, which I'm thinking is a bit improbable.

I cautiously declare success.

 

Congrats! 40mph is not improbable, especially with a tail wind.

All 2-strokes will smoke a bit as they are always burning oil, but you can make sure your using the right ratio and use a high quality oil and it will all but vanish...until you gun it that is and burn away the crusties. You can also use MMoil or SeaFoam or STP upper cyl lube in place of some of the oil mix and it will smoke less and stay cleaner.

 

I couldn't help you make it a better ride, but I love this thread

 

I don't know that anything can make it a better ride. The objective was more to make it a ride rather than a push...

 

injection or premix ? either way, spend the $ and get 2 stroke oil for a motorcycle not lawn-boy or outboard marine engine oil. it will make a differance.
remember, all things being equal, more oil = less gas = leaner mixture = bad things

 

Injection - there is an oil tank.

I thought it was interesting just how dramatic the effects of too much airflow were.

If this thing were mine, I'd do some serious modding to it, rebuilding some of the electrics, tossing the stupid alarm and blinker beeper, and maybe getting rid of a bunch of plastic, just Mad-Max it with some aluminum sheet and rivets.

This is what it looks like now:

 

air flow?? Seriously this thing MUST breath through a straw. Consider that you could keep the entire combustion chamber in your pocket!

Looks like a frog. Add a lightening bolt and it will go 5mph faster.
