hi guys new to this site from wales, i have a fzr 600 and a dt 50 field, the fault is on the dt 50 i have a spark when i have the plug placed in the plug cap and held to the engine block but the spark is not between the electrode i changed plug but still the same, i took the cap off there is a goo spark jumping to the ground, i changed the cap put the plug in and it is still not jumping across the electrode but is jumping from the thread of the plug
