When bleeding the brakes
Front right caliper, bleed this with the front brake lever, ensure that you always have fluid in the reservoir on the handle bar by the front brake lever.
Front Left Caliper, this is bled by depressing on the rear brake pedal, make sure that you have fluid all the time in the rear reservoir
Back brake, use the rear brake pedal again make sure the reservoir is full
Bleeder at the top of the steering neck (under the Fairing) this is bled by pressing on the rear brake, if you find there is nothing coming out of it, the air may need some help getting up to the bleeder, put some weight on the rear brake pedal and leave it for a few hours, the air will eventually make its way up to the bleeder.
My 86 was a bit of a pain when I first got it as there was lots of air in the system and the fluid was real dirty.
Good luck
