Doctor Miracle

I have a 1979 XS750. It was a great deal so I had to buy it. But it is a little too tall. By a little I mean a lot. I'm about 5'8" and it's keeping me on the tip of my toes. I tried adjusting the rear springs but that did absolutely nothing. Anyone have any suggestions? I was thinking a lower profile seat but I would not even know where to begin to find one. Maybe some aftermarket rear suspension. Again, don't know where or what, or what combination I need. Any help would be greatly appreciated.

I need some assistance. I have a 1979 Yamaha XS750. It is very used but runs good. I bought it from a guy and he said that when starting in the cold it would run the battery down and he used a combination on starter and kick starting and it worked. So it starts up, I ride it home, and it won't start back up. I check the fuses and one is blown so I replace it. When starting it gets warm and then blows. This fuse controls the lights and the starter and everything. Without it, nothing seems to come on. It had a 32V 15A fuse. Do I need to get a bigger one? The battery is a little old, is it causing the fuse to blow? Is there a common place where shorts occur? Just need some help, weather is clearing up and I need to get out on the road. P.S. Don't know if it is relevant but my blinkers don't blink, they just stay on. Thanks in advance.
