Help with Earth point.

Hello everyone
A mate has a Gilera runner 07plate (New Shape) and it cuts out sometimes while riding but its like it just looses its spark there is no way you can try and keep it alive with the throttle. Anyways i have tried a new Ht Cap and Coil With no success....
Next thing i want to check is the Bikes earth. But i dont have a clue where it is on a new shape Gilera runner help please....

 

Theres a few of them, im not familar with thew new shape but theres on the left side of the bike under the fairing and i think theres another under the fairing at the left side of the tank.
There'll be another going to the engine aswell.

 

its perfectly ok to add extra earthing points you know

a lot of mechanics do it on classic cars etc when chassis corrosion makes the original earthing points suspect

 

Get your hands on a voltmeter stick it on continuity test (Beep test) Put your live on cable going to battery live and stick earth on some bare metal ( a screw hole ) if it beeps clean its earthing maybe tape it down shake the bike around and see if the beep alters if so bad earth :cheers:
