Engine cuts out when put in gear

[Dead Eye]

Work completed;

Remove front fairing, remove light unit from fairing, replace fairing mounting bracket, replace light unit, attach to new front fairing. Remove front forks, strip them down, replace seals (oil and dust), replace fork oil and replace inner fork legs, rebuild forks, reattach forks, reattach front fairing, bleed front brakes.

That's everything - I guess I will need to go hunting after I get a battery for my multimeter. I don't have the spare parts to create a simple light bulb test
