Symba / Re: Possible source found of illusive mixture screw for symba carb?
« on: September 21, 2021, 02:46:56 PM »
The Yamaha air bleed screw arrived today, and it includes the spring, and seat washer.  The screw is clearly different than Symba, but as it turns out, it seems to work fine.  The screw threads are the same, but the shaft is shorter on the Yamaha.  The included spring is shorter than the Symba by the same amount.  I installed the Yamaha screw and spring, and they seem to work fine.  I was afraid that the screw threads may stop before the shaft reaches the seat, but they do not.  The Yamaha screw simply screws in further than the Symba, but it does finally bottom out on the seat.  I made a test run, and the best idle position is about the same as with the Symba screw.. one and half turns out works fine.  Idle is good, no hesitation when going from idle to full speed, and I didn't have to adjust the idle speed screw.  If I screw in the air bleed screw while the Symba is idling, the engine stops, just like it should.  Here is a photo, showing the difference.  Yamaha on the left, Symba on the right:

That photo appears to be one I took and posted on this forum.  See this post:

I don't see any part number listed in that UK ebay ad, but the measurements and thread appear to be the same as the Symba.  Ask the UK seller for the part number of the screw he sells if he has it, then see if it is 75-23013-Y001.  I don't think it will be.   Report back here what he says is the part number.
Looking at Partzilla, the part number for the air bleed screw for a Yamaha DT100 is:
16 AIR SCREW SET | M4-043
22K-14104-00-00 and they are in stock for $5.06 plus shipping.  That may be the part that the UK seller is selling.  At that price, it is worth a try, and it looks like it might be the right one for a SYMBA.  I just ordered a 22K-14104-00-00 from Partzilla, and the total price was $15.31 with shipping and sales tax.  It will come in a week, and I will see if it fits the Symba.

Symba / Re: Gas overflow / overfill issue without smog/pollution system

It looks like you and i are the only ones who still have an interest in Symba's.  Not sure how you can get better help.  For what's it worth, I overfill the gas tanks on both of my Symbas almost every time I fill up, and have never had a problem doing so. 

The fact that your engine fires and runs for a few seconds, tells me you are chasing the wrong direction worrying about your electrical system.  All of the work you did with the charcoal canister and the various tubes you mention would point me in that direction.  Either an important hose isn't hooked up correctly, or you didn't restore all the parts back the way they were before you cleaned everything.

Slight resistance differences in your new spark plugs is not important and has nothing to do with anything.  Put the ohm meter away.

This is my last post in this topic.  I can't help you and it looks like no other symba owners are on this forum..

Most likely, you either have no gas in the carb float bowl, or no spark at the spark plug.  Open the float bowl drain screw on the carb.  if a lot of gasoline runs out, then you had gas in the carb float bowl, and that is good.  If no gasoline runs out, figure out why no gasoline is getting to the carb.

Remove the spark plug, and while it is still connected to the high tension lead, ground the metal threads to the frame, and turn over the engine, using the electric starter.  If you see spark at the end of the spark plug, that is good.  If you don't see any spark, figure out why not, then report back what you find.  Also, please stop using the word torque.. it is not the correct use of the word.  I think you are trying to say is that the engine turns over, but it doesn't fire.

I do not know the term turnover torque.  Do you mean that the engine won't turn over, or it turns over slowly but won't start, or something else?  Will it start with the kickstarter?

That one looks like one of mine!

That is great news!  looking for you to post a photo..  If it turns out you need a part or two, I may have a used part that will do.  I bought most of a basket case Symba, less frame, wheels, and body panels a few years ago.  If I have something you need for your new ride, let me know and if I have it, I'll send it to you for free, with free shipping.  By the way, SD is mostly out of Symba parts now.  When you click on a picture of a part on their web site, often it will say not available.

  As you know, Super Cubs have come in various sizes through the years.. 50, 70, 90, 110, 125 ccs and perhaps other sizes, and I can't speak to whether any of their parts interchange with a Symba, but my guess is no.  I have two Super Cub 125s and two Symbas, and no parts interchange.  I was able to fit a front rack for a Super Cub 110 to both of my Symbas, and managed to carefully bend a Super Cub accessory 110 rear rack to fit one of the Symbas.  Getting parts for a Symba is very difficult in the US.  Every now and then someone breaks one up and then sells the parts on eBay.  The last time that happened, I bought all the parts from that Symba, and put them on the shelf in case I needed them in the future.  So far, I haven't needed any of those parts except for the fuel level sensor.

These guys have some parts, but as the parts sell off, they are gone:
When you click on a specific item, you might find that it is "Out of Stock".

I don't know what the parts situation is like in Australia, but in the US, one should not count on parts being easily available.  If you find a good source, please post the info here.. thanks.

Here is another one I made yesterday with my other Symba. In this one I drive out "Follow That Dream Parkway", to visit the spot where the Elvis Presley movie "Follow That Dream" was made almost 60 years ago.

 I realize that there aren't many people left on the forum who still have their Symba's, but I just uploaded a Symba video over the weekend. It is mostly about 45 minutes of riding one of my Symba's around a lake near here.. pretty boring unless you like Symba's and the sounds they make.. LOL..

I looked this morning on the Scooter Dynasty web site just now and don't see the shocks.  Please send a link to what you see or provide more info. 

I assume you are looking for new ones, but there is a pair of used ones on eBay, with a lot of rust on the chrome, but better than nothing if you have none right now.  It is rare to find any parts for Symba on eBay, but a couple a weeks ago, someone took apart a pair of Symbas and posted the parts.  The shocks are here:

New Symba parts have pretty much dried up in the US now.. same for Wowow parts in Asia.. It would be great if someone would post links here to any shops with new parts..

Symba / Used Symba Parts now on eBay
« on: December 01, 2020, 07:35:01 AM »
I haven't seen many used Symba parts for sale on eBay in the past couple of years, but in the last few days, someone has been listing a lot of parts for sale.  I do not know who it is, and it is not me.  If you want any Symba parts, you should act now, as they are getting harder and harder to find.  Here is the link:

Symba / Re: Replacing Vacuum fuel Petcock Symba 2009 filter tube
« on: December 01, 2020, 07:11:54 AM »
You first have to unbolt the large flat painted plate that surrounds the filler neck and to which the seat hinge attaches to.  Remove the battery, so you can reach through the battery mounting area to remove the various hoses that connect to the tank.  Then lift up that painted plate, bringing the gas tank up with it as a single unit.  It is somewhat difficult to get the tank up though the chassis, but if you twist it exactly the right way, you can do it.  Then once the assembly is out of the chassis, you can remove the tank from the painted plate if you need to, or simply leave the painted plate attached to the tank, and change the petcock. It is a very miserable job to change something that should be simple, because of all of the vacuum hoses involved.

Start by first reading section 3-12 about this in the workshop manual, see:

General Discussion / Re: What is the latest news from SYM?
« on: November 28, 2020, 07:33:31 AM »
Thoppa.. thanks for those links.. they will be helpful.  We get daily news from HK here, but very little news from Taiwan.. 2020 was the first year in five that I haven't visited Taiwan and HK.  Last year, I visited KYMCO in Kaohsiung City, and on the way saw the rising popularity of Gogoro scooters.  As you know, scooters in Shanghai, and perhaps many or all of the major cities in mainland China are now all electric.  I wonder if SYM is working some electric scooter or motorcycle deal...
