I have an Evo 125 with a starting problem. When it has been stood for a few hours or overnight, it takes maybe 10 cranks or more to get it started. Within a couple of hours of it last running, it starts immediately.
The battery is fine and the plug is sparking well. This leads me to believe that it is a fuel feed issue, but once fuel is in the float chamber, it should stay there until the next start! There is no petrol smell or evidence of a leak.
In the manual there is mention of an auto bi-starter. Not sure what this is, or what it does, but could this be the problem?
Any advice would be appreciated.
