Ipswichram Posted March 3, 2014 Share Posted March 3, 2014 I have a 61 plate YBR which has just started hunting between 1000-2000 rpm and then stalls. Any idea what can cause this? My local dealer has never heard of this happening before. It has done 530 miles from new and has always been garaged when not in use. Any help will be gratefully received.

neversaydie Posted March 3, 2014 Share Posted March 3, 2014 3 to 4 years old and only 530 miles? Fuel system/tank/fuel filter gummed up would be my first thought Link to comment Share on other sites More sharing options...
Ipswichram Posted March 3, 2014 Author Share Posted March 3, 2014 Yeah, I had a bad injury which has limited my riding. I'm eager to catch up. I will have a look. Is it worth replacing the fuel? Link to comment Share on other sites More sharing options...

Ipswichram Posted March 5, 2014 Author Share Posted March 5, 2014 I've found the problem. The spark plug I'd arcing against the radiator baffles on the engine. New lead? The spark plug looks fine with no scorching on it and the lead looks good on the outside. Link to comment Share on other sites More sharing options...
