Hey everyone my name is Sam and I just recently bought a 1981 honda CB750 it's my first bike and in need of some work. The body is in great condition just needs a fresh paint job. However, when I purchased the bike it ran just, not so well. I was wondering if maybe you guys might be able to help.

Welcome to the forum Sam, I recently joined myself & also have an 81...great bunch of guys here LOTS of info.

The issues:
When the bike starts you have to constantly rev the engine otherwise the bike dies out.

Since purchasing it when I go to turn the bike on you hear a click when attempting to turn it on but the bike itself never turns on.

The bike backfires. I have a hunch that has to do with what the bikes idle is set to but Im not quite sure how to adjust it.

My first hunch would be this is a carb issue. Dirty, gummy, out of sync or all of the above. (don't rule out bad gas in the tank.)

Thats about all mechanically that is wrong with it other than that its just some electrical work like hooking up the turn signals and the brake and front light which ill deal with later but for now if anyone has any imput on those problems I would greatly appreciate the help.

Also I am looking for the repair and or service manual for this type of bike im not sure if its a f or a k class all i know is that its a 81 cb 750.

The Service manual is here, you just have to choose which model addendum you need for your model (check the neck plate on the bike):

That was a godsend to me, I also bought the Clymer manual.
I have put the 750 Custom & K model owners manual in that thread as well. Mine is a K,
 

assuming that no one has modded your bike if it's a K it will have spokes, a rear drum and no tail piece.

The F looks like this:

And I know im asking a lot here but does anyone know how to customize my seat cover. The seat has a few tears in it covered by duct tape. Although thats a classy look I was hoping to put maybe a white colored material on the seat instead of the classic black.
Thanks!

I would recommend skinning it gingerly, blowing the stitches & making a pattern. Once you make a pattern, anybody with a heavy duty sewing maching could sew you up a new skin. (ask some dry cleaners/ tailors who work on leather coats)
