The battery positive wire connects to a set of fuses and a starter relay. The battery negative connects to the frame and, depending on the design, perhaps to fuses and relay. You should be abe to trace the wires and their connections. If you can't, sorry, but give up. You are not going to be able to fix an electrical problem.

If you think the problem is electrical, first check the battery voltage with a meter and if that is about 12.8V, the battery is good. Also check the fuses - pull out each and inspect it to see if any are blown.

I'm not familiar with the HD or 200 models - download the manual and follow what it says. https://www.manualslib.com/manual/1010855/Sym-Hd200-I.html

But honestly, I would not spend any money or much time on such a high mileage machine. It's at the end of its life and has no commercial value. Even breaking it for parts ... who wants parts from a worn out machine.

Well if they replaced the bolt and didn't add any specific charge to do it, I'm pretty sure I wouldn't have mentioned it either.

Hi,

Welcome to the forum.

It's covered 111,000 miles and now it's been crash damaged and won't start? it's a total loss. I'd scrap it. Not worth any time or money.

all the best

Good to hear both machines are running again :-) Did they say how they removed the SYM's pinch bolt?

Aha. I did wonder what a cross-head was doing as a clamp bolt - it would be far too easy to round off the slots with the torque needed. It's quite hard to round out an allen head though, and I assume the head of the bolt is recessed too, so you can't get mole grips on it, or use an angle grinder to cut a slot in it. So you can try an imperial oversized allen key or a torx key, and hammer in the key. I'm guessing you don't have a screw extractor tool, or welding gear, or metal-based epoxy glue so those aren't options. Like you, I wouldn't bother trying to drill it out - it'll still be very hard to remove - and repairing the shape using needle files will take too long too.

I replaced that allen bolt with a regular raised hex head some time ago, but that was because the threads in the fork had been damaged - it didn't feel good when tightening it up - like it was ready to turn too easily, not tighten up. So I used an extra long bolt to reach into deeper threads, with a thick washer under the head. The washer helps distribute the load - essential because the recess in the fork for the allen head creates a gap under the washer, so the washer has uneven load across it - hence it needs to be thick steel. Without the thick washer, the bolt's head would experience the uneven load and would be more likely to fail in time. Stress will concentrate around the base of the head, and it will work on microscopic cracks, leading to catastrophic failure - the head will shear off. With the washer, it should be fine for the load, but it's not ideal. If I could get a longer allen bolt I would.

Hi,

You can also try large mole grips / locking pliers / grip wrench - this has worked for me sometimes - if you don't want to wait. 

And I've also used an angle grinder to cut a slot in the head of the bolt so I can use a slot-head screwdriver on it however, this can go horribly wrong (head shears off if the slot goes too deep) and from what you say, there probably isn't clear access for the angle grinder.

I think the biggest collection of SYM mnuals is here
https://www.manualslib.com/brand/sym/motorcycle.html

It's quite likely that the engine is the same as other 50cc scoots of the same year so you can try another model, same year?

Most of the manuals have fault codes in them, although some are easier to follow than others.

General Discussion / Re: Do SYM scooters use a GY6 engine??
« on: June 26, 2021, 11:03:36 PM »
Hi Cibby,

I have seen a ton of GY6 parts on Taoabo but it seemed to me that they weren't all for the same engine, with some for a 125 and some for a 150, a 200 and a 250. Here's an Alibaba version showing different engines with GY6 tags.
https://www.alibaba.com/countrysearch/CN/engine-gy6.html
So I googled it and found GY6 engines are not all the same it seems - GY6 is a common design with variations.
https://www.infobloom.com/what-is-a-gy6-engine.htm
So I think you've got some major work to find out if a part will fit or not. I found this page on engine unit codes - maybe it's a start?
Lets disect the code starting with the first digit:
(Digit #1) Corrasponds to the number of cylinders. All GY6 engines are single cylinder, so this number will always be 1.

(Digit #2 and #3) This is the bore size in metric millimeters, in the case of the 157QMJ, our bore is 57mm. Note that 57.4mm bore engines fall under the "57" designation.

(Digit #4) relates to the style of engine. All GY6 engines are designated "Q".

(Digit #5 and #6) The actual size of the engine. The second letter ascends consecutively for each 10cc. MB = 50cc, MC = 60cc, MD for a 70, MH = 110cc, MI = 125cc, MJ = 150cc

That is pretty much it for the standard codes stamped on most GY6 and other Chinese engines. We will add more information about manufacturer-specific codes as we find it out.

Sorry to hear it died but at least you weren't far from home when it did, and breakdown recovery is a wonderful thing! I can't believe Honda are telling you to wait a month. It's probably corrosion that could be fixed in under an hour.

Many years ago, I was touring in France on a Yamaha YZF600 and the gearbox died in the middle of nowhere. I waited six hours for the RAC recovery vehicle, and my Yamaha took 3 days to fix. A bolt had worked loose, that was all - no parts required. Thankfully, the RAC arranged a hire car for me as part of the breakdown cover, and I think they were calling the Yamaha garage to get the repair done quickly because of that. I was so thankful I had breakdown cover but 3 days just to  do a bolt ... I would be quite upset if they had told me a month. No wonder you don't want the machine anymore. Which Honda dealer is it?  Have you posted this on a popular site? Sometimes the negative PR can induce a company to get their arse in gear.

Citycom 300 / Re: Only use 35 watt H4 bulbs or bad things happen
« on: June 19, 2021, 03:24:58 AM »
Hi,

Why do the bulbs blow - is it just too hot and dry there? Dirt/Sand on the bulbs's glass concentrating heat?

I changed to 10W LEDs so I haven't had any problems. But the change wasn't straightforward because there is a "headlight control unit" that requires a significant current drain to turn on, and 10W was not enough, so I had to replace the HCU with regular automotive relays. So if you do decide to get LEDs, get some high wattage ones, making sure they'll fit as the OP noted!

I hope it works!

Yikes! Europe has annual emissions tests - my bike in the UK is an XT660R 2005 - it is one year too old to be allowed to go into London's ULEZ for free - £12.50 a day. The same bike in 2006 was certified Euro 3 so it doesn't have a fee. How dumb is that. https://tfl.gov.uk/modes/driving/ultra-low-emission-zone/ways-to-meet-the-standard

Hong Kong has only one measurement, when it is registered, and 2 wheelers are never tested again for anything, not even roadworthiness. However, the Police can simply notify riders that they think the machine does not look roadworthy and then we must get it tested.

In a way, you're lucky there's no testing, but it means, same as here, we'll be the last to get the new versions.

Frustrating eh? But I don't think anywhere gets all the models on SYM's site? I know UK, Taiwan and China get a limited range too - I tried to get a Citycom in Taiwan on a trip a few years ago but it's export only. The Hong Kong importer here briefly had two 16"wheel models 12 years ago but they didn't sell well so they stopped importing them and refused to order a new one for me.

Hong Kong has the TL500, Cruisym 300, Joymax Z 300, Joyride 200, Jet 180 (cos it's made in China) and DRG 160. It seems 3 of these models have been refreshed/replaced - the TL500, Cruisym and Joymax Z - and the Z+ is now available in Europe but it's not available here. We don't have Euro5 and SYM said we won't get the Z+ for another 3 to 9 months - that sounded to me like they'll keep selling the Z until stocks are fully depleted. 

Since my Citycom is running well again tho, I don't mind the wait. I'd buy another CC if I could but I simply cannot get one. I've just come to accept it. One of the reasons I'll get the Z+ is that the Z is one of the models sold in China so I'll be able to get parts without getting ripped off by the importer here.

Hi,

Has the US adopted Euro 5 standards or its own version of them? If not, then I guess it's likely it'll be the main market for the Euro 4 versions, while Europe gets all the refreshed Euro 5 models this year. Euro 5 came into effect for existing models 6 months ago I think, and the SYM range has been refreshed for this, as with many motorcycle companies, so Europe has been getting a load of refreshed versions of existing machines this year.

Hi
rang motogb the uk importer and aked if there was any intention to bring the Z+ or cruisym alpha to the UK, they said no at the moment unless SYM agree an attractive price agreement

Hi

Good news - the Z+ is available for order on the MotoGB website - the 300 is £4999 +OTR - blue, white, silver, or black. How does that compare with the price of the Z?
https://www.symuk.co.uk/index.php/buy-online/2021-sym-joymax-z-300cc-893

The dealer here in HK still doesn't know, so I contacted SYM directly in Taiwan and they said last quarter this year, maybe first quarter next year. Um.
