Thanks so much that sounds exactly what's happening. I'll try with WWD40 - cheers!

I'm in Edinburgh.

Yeh it unfortunately sits outside all the time and the weather's been awful. Good advice, thank you

Thanks guys

Hello everyone. I have a Honda PCX 125 and it's 4 years old with just 5k miles. No problems at all until today. It starts fine and goes fine but every time I twist throttle more than a little it cuts out as though it has stalled, splutters a bit but then starts again on button ok. Rides no problem at all as long as really gentle with throttle. Any thoughts what this could be? I have notoriously been burned by mechanics before and would be good if I had some idea of what it is before I take it in. Thanks so much for your time in advance.
