new guy to the scene, making my first monster

This is my bike, 79 kz1300, as for what I'm envisioning for it, imagine a pit bull born with one leg in the back, a fully functional rear leg, like that was the natural design all along, so your looking at its a big mean beefy looking Pit, with a suddenly slimmed down but monsterously toned and built leg. I want to do full performance mods on it(from brakes to Valves, b-v, a bubble front windscreen, pretty much everything on this bike.needs doing, I picked it up from an old shop in my hometown where it had been rusting away, so I picked it up for a good price and rolled it into my suv same hour.
