Problem with SV cutting out

hi Tiptop here
New to SV's but I have been biking for 30 years so I thought I knew my way round a spanner!
I have a K4 650 N which suddenly started to cut out under load. If you just pootle around no probs, but when you wind it up bang your on a cangaroo.

So far: new plugs, caps, drained tank ( no water ), Inj. cleaner, replaced both coils, checked fuel pump, and kicked it. Help! any clue

As it seems you have changed and checked a lot. Seems it may be a electrical problem.

I say this as on my k2 i had same problem and it was the wirring near the headset and the N from the battery. But that was on my k2 and k4S are different hopefully someone with more brains will be along shortly.

Btw welcome to the org :)
