Few problems

87 700 intruder. I just bought it and on the way home had a flat on the rear. Loaded up and took home changed out the tube.now I have a shake that seems to come from the front but it doesn't make sense since the front wheel hasn't been touched. Both tires were brand new when I bought the bike. The shake occurs throughout the speed but more noticeable from 20 to 60mph. Would a tire being out of balance cause this exact thing? Would the back tire make it feel like the front is producing the shake?

Absolutely; did you not have the tire balanced? In any case, if the tire is wobbling from side to side, which may not show up when balanced, depending on the person doing it and the machine, that motion can be transferred through the steering to your hands. If you have access to a lift, spin the rear wheel, and watch for the tire squirming side to side; a pencil taped to the swing arm will reveal small deviations. Since the only thing that should have changed is the tire, unless the rim was bent during the flat, it is probably a bad tire.

If it sat a while before you bought it and the tires lost some pressure, that would cause what you're experiencing.

Could be a flat spot, but I'd start by balancing the tire.

I replaced the weights on the back wheel after putting the tube in but it seems like the shake is coming from the front. If looking at the front tire when at speed it has a wobble to it but I haven't touched the front. When I get time I will pull both wheels and balance them to start.

First, the balance weights counter both heavy spots in the tire and the tube; even if you marked the rim and tire so they are back where they were, putting the weights back where they were probably didn't reset the balance as it was.

To see why an imbalance in the rear wheel can make the front wobble, try this: sit on the bike, and very lightly hold the bars straight, then have a friend grab the rear-most part of the rear wheel, and pull it side-to-side. What does the front wheel do? The caster and trail of the front wheel should transmit that wagging to the steering.
