GasGas EC 125 -09 issues

[gglucas]

So my GasGas wasn't reving all the way out but I were still riding it, and now fue days ago it just wouldn't start at all altough it has spark and fuel. I have replaced the spark plug and the ignition coil, checked stator, flywheel, carburetor, cylinder, piston, reeds and still won't start. What could be the problem? Any help would be appriciated.

Check the ground connections. I had similar issues on mye 06. A bad ground connection at the ign coil was the culprit

Have you checked the compression? Was it smoking badly last time you rode it? You should also check the crank seals. Open the ignition cover and smell for gasoline. Also smell the trans oil for the smell of gasoline. if you smell gas in either you likely have bad crank seals.

~1week old 98 petrol with 2,5% oil mix, should be good.

While you have the ignition cover off make sure the balancer is not loose. If it got loose it could have changed its timing.

Did a compression test and it has 9bar, should be ok? Opened the igniton cover couldn't smell any gas, just a slightly burned/corrosion kind of smell, and everything sits nice and tight there.

Have you tried a quick spray of starter fluid?

 

[gglucas]

no, I didn't even know there is such a thing as starter spray, thanks for the tip I have to try it

You need to be careful with it but it is a useful tool to diagnose problems and verify you are actually getting fuel into the engine.
