I replaced ther starter on my 86 454. After getting it put back together, when I turned the key none of the lights came on. The battery is good and voltage is getting to the wires connecting to the battery. Any thoughts?

check ALL fuses first

Definitely check all fuses front and main. If you have the starter disconnected with the battery still in place I think one of those starter leads is a live terminal that might pop the main fuse if it touches an earth. I tape the starter terminals up so I never have to find out!

Ok. Replaced the fuses and the lights come back on. Thanks for that!
However, now when I press the starter button I get a single click from the relay. Any recommendations?

Just a click when starter button is pushed, indicates not enough voltage to turn the engine over, but enough to operate lights. put a battery charger on the battery and give it a good charge.

Ok. Charged the battery all the way and am still getting a single click. Here is a video for reference.

Sounds like something jammed......May need to remove side cover & look at starter clutch & drive chain.

Yes.....Also may be something jamming the starter clutch. (broken magnets) |

I took a look at the starter clutch and things seemed fine. I didn't move the starter sprocket all the way as I didn't have a tool to do it, but it spun freely (see video). I put everything back together, wired it up, and it turned fine (albeit kind of sluggish). Must've crossed some wires or something.
I sprayed some starter fluid in the carbs, turned it, and noticed that it would turn smoothly at first but then start to become really sluggish (see video). The bike also popped on the right cylinder, I believe, and when I went to check the compression it had dropped in that cylinder to 90psi from 120psi. I didn't get time to check the valves but I plan to. Wanted to run this by everyone to see if they had any recommendations.

I think valve adjustment is defently your next step.

when valves are set try using a car battery and jump leads to turn the engine over,that was the only way i could get mine started after a long winter. you can spin it over for a greater time at full power

Took pya977's advice and used the car battery. That seemed to help it turn more smoothly.
Checked the valves and played around with their clearances in the recommended range for the R cylinder only. I could only get the compression up to about 90 or 100 psi. I put about a 1tsp of oil in the cylinder and the compression stayed in that range (so at least the rings are still good). This makes me think that a valve is stuck open on the R cylinder. Do others agree and if so, are there any ways to overcome this without pulling the head?

You can tell if a valve is stuck....the valve stem will not go up and down, if it is stuck.....if a valve is burned and not sealing, that will give the same effect. Pulling the head is the only way to check for a burned valve. 90 lbs compression is not good. When checking?adjusting valves, make sure the cam lobe is opposite of the adjusting screw, and valve stem.
