Keeway F-ACT/RY8 Scooter Cold Start Issues: Starter, Kick-Starting, Carburetor & Spark Plug

Question

Hello Probably best to ask in this section :) I have a problem with my KEEWAY F-ACT/RY8 scooter. When it is cold it does not want to start either from the starter or from the kick. It only catches on after a long digging. You have to hold the revs a little to keep it from stalling. Once it warms...

_milcek_ · Answer

I suspect that the automatic suction has its whimsie and sometimes it works sometimes it doesn't. Try starting with the throttle open to 50% no more. I somehow got used to it, but as I was inexperienced, I fired at full opening and there was a long problem with firing, so I had to dig for a long time.

Check the compressions if you have like.

Juhas19 · Answer

Let me say this - problems with starting a motorcycle, especially in winter, are a problem for Japanese motorcycles. If we are in a hurry to start, we should dig, dig and dig again. In tragic situations, sometimes it helps to unscrew the candle, clean it (sometimes it will collect carbon deposits and other crap or will simply be flooded with fuel) and possibly heat it with a lighter or a candle to raise its temperature a bit (certainly a motorcycle, after nights in the garage has a low temperature of the engine and its guts )

Have you checked/replaced the cables?

=> DJ Max - I checked if there is a spark - everything looks ok.

=>Juhas19 - dig, dig - sure, but not for 10-15 minutes :)

=>Uszol 1990 - compression is rather ok. Because when it starts and warms up, it pulls as it should. I have no idea how to check compression because there is no manual transmission.

=>_milcek_ - throttle at 50%, i.e. Unscrew the throttle a little and then start?

Uszol 1990 · Answer

Compressions? you have to have a clock that screws in instead of a candle you can check the suction if it works fine.

linx · Answer

Check out that little choke device in the carburetor. Generally, if the scooter / motorcycle is cold, it starts without gas. P.S. 2000 km and no warranty?

mrrudzin · Answer

hmm...
But when it warms up, everything is ok. The power is as it should be, etc. And it starts without a problem. So (I guess) compression is ok? Unfortunately, I have no way to check

And how to check the suction?

My knowledge of all kinds of motorbikes stopped in the era of Jaw and Komarków. There was no automatic choke, there was a manual gearbox, etc.

Check out that little choke device in the carburetor.

It's probably what hubiwit's friend wrote about. The resistance of this device is about 30 ohms. We tried to disassemble the crap, but either they changed the glue or someone gave a little more. It's not going.

Lechu_AF1 · Answer

Basically, I feel sorry for you for buying a Chinese. Just like this guy who recently wrote that he doesn't get the Taiwanese TGB Bunny. You have only driven 2k km and you have no warranty?

Advice on how to fix the problem:
Buy yourself something European or Japanese...

mrrudzin · Answer

Not really, I just bought a friend for my son. I'm a bit too old for these toys. As for the warranty, I'll have to ask.

I know it's easier to buy a new one. But once you get into something, you have to try to deal with it

wnuczek · Answer

In fact, it may be a problem with the automatic choke, unscrew the carburetor connector going to the air filter, close the carburetor inlet with your hand, leaving only a small passage and try to start, this way you will enrich the mixture by limiting the amount of air. You can also do this, the next time you try to start, turn the starter a few times and then remove the spark plug, if it is wet, it is a sign that fuel is reaching the combustion chamber and it is very possible that the spark plug is flooded or the fault is somewhere in the ignition.

linx · Answer

Connect these cables to the 12V power supply/battery for a moment and see if this needle/stem slowly extends and after switching off it completely (!) retracts. Maybe vice versa depending on the model. Plug the air inlet to the filter with your hand, as your grandson friend writes, then it will surely ignite, just an attempt to start without gas. Recently, we had a problem with the keewey focus, it was cold, it fired up only after touching the filter with your hand.
Scooter unlocked on carburetor or not?

TomLib · Answer

after all, the choke works mainly when the throttle is fully closed! Then all the vacuum sucks the fuel from the intake nozzle and gives a rich mixture. After opening the throttle, there is less vacuum and the idea of \u200b\u200b"sucking" is a bit pointless ...

As these colleagues advise - see how the piston behaves after applying the voltage. Recently I had a case that it also had resistance (I don't remember at the moment what kind) but it didn't want to pull it in (even with the help of a hand).

Also check the valve clearances...

Uszol 1990 · Answer

It's a two-stroke, it doesn't have valves

TomLib · Answer

sorry, looking at the photo of the carburetor you are probably right that it is a two-stroke Instinctively, seeing a Chinese or keeway, I think of a four-stroke licensed by Honda

Afcht · Answer

Winam, the problem of this is the sleigh for 100% I had such cases more than once, the sleigh is about PLN 100.

Added after 2 [minutes]:

what is in the photo is a two-stroke four-stroke with larger carburettors

alucardxD · Answer

Most 4 stroke carburettors are diaphragm carburettors.
so they are older
this sleigh costs PLN 35 mieloch.pl
listen, the scooter was probably badly run in, remove the cylinder and see what condition it is in and what are the rings
maybe just replace the rings
before buying a sleigh, unscrew it from the carburetor and the sleigh is connected to 2 cables connect it to the battery and see if such a pin will rise in the sleigh

mrrudzin · Answer

Suction is this module with two wires? How much should the needle move? Should it hide or protrude?

sk700 · Answer

Kick it about 20 times with the ignition off, then turn the ignition on and give it 1/8 throttle (if you overdo it, it will choke) then kick once, and it should catch right away.
If it fires, hold the gas for another 5 seconds. (do not add gas or it will choke)
If that doesn't work you can try spraying something (e.g. Plaque) into the carburetor through the air filter.

PS I have exactly the same with aprilia sr

.

Anonymous · Answer

Plak, as far as I know, is used to polish the upholstery in cars. A self-starter would be better.

sk700 · Answer

JERZYKOWSKI True, but it's about flammability - almost everyone has a plaque at hand and it's a proven method . PS you can also self-start, but not everyone has it in a scooter .

rickoo69 · Answer

I'm all for no compression. I once had a malaguti f-10 with the same problem (kicking 10 minutes in the cold) and it turned out that instead of 9.2 atmospheres (or whatever compression is measured in) it was probably 5. I advise my friend to check the compression. I suspect it should be around 9.5 atm. Of course, if you're 8, you shouldn't have any problems with smoking either. and as for the earlier statements, you can also take some gasoline in the syringe and pour it directly into the cylinder through the intake port. usually you don't need to repeat it. Regards

mimor555 · Answer

well, it did to me too ... I gave it under warranty ... setting the valves and cleaning the carburetor

Pawlak samodzielny · Answer

Colleagues I had the same problem. The valves are too tight, I made a small slack and it fired without any problems cold from the starter, the exhaust just did not close completely, check it out. Regards.
