neos 50 with no spark?

once again the neos has caused a 7 mile walk thers no spark at the plug ive tried changing the plug,still nothing the batts fine and the main fuse any ideas? ick:

 

is the coil pack wot the ht lead is attached to? also the plug seems dry but theres fuel n oil running thru the pipes, it cut out a few times n restarted no prob then got a noise n that was it.

 

now will spark once in a while but also shocks u thru the brake lever

 

threw the brake lever lmao? what! never heard of that happening. and yeah the coil pack is what your ht lead is pluged into

 

Faulty connection, wired up wrong at the coil sounds like it,

See if it shocks you anywhere, Like the engine frame its likely the whole bike is becoming live due to someone sticking a live wire onto an earth point, or its touching earth and touching live at the same time, Aka sometimes sends power to the plug or sometimes sends it to the frame

 

thers only 2 wires on it 1 plugs direct to the coil the other bolts to the frame as an earth
kepps making the batt flat

 

now have spark but it still will not start, even with new piston?
