CG125 Died

[Gashead Harry]

Last night pulling up to a roundabout I was breaking and stopped but the engine lost revs and died. After this the bike will not start but it backfires on pretty much every kick. Tonight I have cleaned the carb about and that does not appear to be the issue. Does anyone know what the problem could be? There is a spark and the plug is wet. I topped up with Shell unleaded V Power about 12 miles before if thats any use.

Contaminated petrol? Had you run into reserve before you filled up? Perhaps had some grit/dirt/rust at the bottom of the tank?

I'd personally get a clean jerry can and empty the tank (you may need 2 actually). Then give the tank a swirl out with new clean petrol, clean the filter on the tap and any inline filter you have, and then put a little bit of petrol in, reconnect and switch it on to reserve.

Thanks for the quick response Alun.

I will give it a go after work tomorrow and let you know the results.

You can get contaminated fuel from any brand or type of petrol.
It can be just at that one petrol station.
Or I should say one of the petrol tanks under the petrol station.

Was it raining when the fault happened?

I also assume you filled up with contaminated petrol.
How much did you put in and how much was in the petrol tank before?

Try a new plug, it could just be coincidence with the fuel.

Contact Shell they can do checks on the garage.
But they will proberbly fob you off.

Well ive found out what the problem is. After following what Alun said the bike still wouldnt start. After that I popped off the rocker cover and the rocker itself (brand new 200 miles ago) was locked solid. At this point I pushed it down to the local bike mechanic and he says where the part was poorly made the tolerances were all wrong and thats what caused it to seize when it heated up. I wheeled it back home as i dont have the money to put it right (again) and put the old one back on and the bike fires up again but makes a right racket. Where do I lie with the place that the rocker assembley came from are they responsable for costs that the defective rocker caused such as van rental to get the bike back and the costs of repair?

Can you adjust the valve clearances on a CG? Should help quieten it down.

It was a genuine Honda CG125W part from David Silver Spares. I also had a genuine exhaust from them which was wildly overchromed around the bolts which needed modification to fit it.
