Why won't my SYM Jet motor scooter start?

original one on bike new one off same year??

I have a 2006 05 reg SYM Jet Euro X 50cc moped.
When I last rode it (a week ago) it ran OK but felt a bit lumpy. I smelled an electrical burning smell, so pulled the front cover off and noticed the relay with the red and green wire was very hot, I waited till it cooled down and inspected it and found the ceramic? was blackened and cracked...

I replaced it with another one from the same year and model and it was different? The one on the bike was 2 bars connected with a bracket with the green wire in 1 and the red wire in the other. The new one is only one bar with the wires on either end...

I also replaced the battery and the fuse (which had blown). All it does now is turn over and eventually floods (strong smell of petrol). There is a constant spark (after I dried and cleaned up the spark plug), but it just won't fire up on the button or kickstart.

Please help as I'm really needing this bike to work.

Sym Jet resistors
by: tuxster

The 2-bar type resistor is a standard part of a Sym Jet Basix. Funny that your Euro X is fitted with it, when the one for the Euro X is the single bar resistor.

I would suggest purchasing the 2-bar type resistor for the Sym Jet Basix as this was the one you pulled out from your scooter.

Hope this helps.

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.

Read our review or go right to Amazon.com to buy this highly recommended Battery Tender Jr NOW...





Attention!

I'm Back!

Yes, I have been noticeably absent from the site the past few months. I recently lost my mother to a long battle with COPD and was subsequently plagued with a bunch of minor health problems. But I'm better now & back full swing.

I had to delete over a hundred questions that had been submitted, some because they were too old for answers to still be valuable and many because they were written in text speak, which I don't accept on the site. PLEASE... use proper capitalization & punctuation, so I can publish your question/review, etc. without editing. Thanks! :)

Wondering why your scooter question never got posted?

Chances are, there is a good reason. Did you...

If you "checked yes" on any of the points above, then I've deleted your post. Sorry, but I have standards. Feel free to re-submit, following the instructions I have everywhere on the site.

Also... all submissions have to be reviewed by me, and that can take a few days sometimes. Comments go live without approval, but still take 30 to 60 minutes to show up, so don't repost them, please.
