TOPIC:

I recently posted some photos of my 79 KZ1000 LTD project bike.  I sometimes just look at it and wonder "Where do I START?". 

 When I first bought it a couple of years ago, I pulled out the rusting battery box and media plasted and powder coated it. 

I also largely cleaned up the inside of the gas tank with Metal Rescue (I believe I should do this again, to finish up....I save the 2 gallons that I used, but not sure how to "refresh" it or if it's done what it will do and I need to buy more?).

And I pulled the carbs off and pulled them apart, labeling each piece and putting them into zip lock bags and took photos.

But beyond that, I'm not really sure what the best way to attack this project IS.   When I look at it, I just want to tear it all apart and media blast and paint (or powder coat) the frame.  It seems that when it's all apart like that, it's a good time to replace any bearings that need replacing, and possibly weld in any bracing (is that REALLY necessary?)

Just looking for some tips on how you guys start a project like this in some type of logical, productive order......all comments are greatly appreciated!

                                   Thanks in advance,

webbie,
   I recently wrapped up my wife's bike   www.kzrider.com/forum/11-projects/614473...1100-refresh-upgrade
and what I did was strip the bike down to the frame, engine & wiring harness. New pieces were appropriated over time & others were refurbished... 1 step at a time. It's kinda like alcoholics anonymous, but for motorcycle people!

If it's a resto or straight rebuild i start with rebuilding the engine then do the frame, fit the engine in the frame and go from there with suspension and wheels to get it rolling and then all the periphials,brakes, electrics etc and bodywork usually last.
If it's a special etc which most of mine are then the bike gets built at least twice or more.
First time or two is dry build and mock up with the major parts to make sure everything lines up and misses any additonal bracing etc and the final build follows the same path as a straight rebuild.
 

Everyone has their own priority sequence and it depends on what your building as zed1015 said.
Personally, I like to do the hardest/biggest bits first. Generally paint and engine as I do everything myself then restore/mod each part as it's taken off the bike. When there's nowt left to dismantle and restore it takes only a couple of days from a pile of restored parts to a finished bike. 

I like to get the bike running and "around the block" ridable, with the least time and money as possible, just to know what I got and better understand its needs, before refurbing.
The neighbors are used to seeing me riding bikes around with no tank, seat, or covers. Just a plastic fuel bottle hanging from the handle bars. I usually make it back home.

Great responses.  Thanks guys.   In my mind, it seems the way to do it is to disassemble everything, and refurb/refinish pieces as they come off.  Finally ending with the frame, with a bunch of refurbed / refinished parts to put back on it after the frame gets blasted and coated (paint or powder).  

What bearings are definitely replace items?

Regarding the engine, my initial thought is to have to top end done.  New pistons/rings, cylinder hone, valves.  But not necessarily touch the bottom end.  Make sense?

Carbs I want gone through from top to bottom.  I honestly don't feel qualified to do this myself.  Maybe it's just fear.   If I choose to send those out, where is a good place to send them?

                                                       Thanks again,

Have you done this before with a motorcycle (100% tear down and restore).  It can take years to finish a project like that, and many many folks never make it to the end before losing interest.  It seems like it's already been in your hands for a few years, as you mention.

Personally, I would focus on the basic mechanical function and safety components, and then ride it.  If you really love it, go all out.  If not, you have a good ready to ride bike that should be easy to sell.  If the first thing you do it create a giant mount of parts, it's a ton of time and work to get out of the project.  Even parting it out is a ton of work.  It's much easier to sell a fully assembled bike.

I've never been hung up looks.  I focus on function.  As you already have done, I have repainted many rusty battery boxes.  And you already started on the carbs. 

Assuming you think the engine internals are not damaged, I would do a valve adjustment and call the engine done for now.  19k is low for these engines.  My Z1R has 45k miles on it and runs great.

I would focus on the following:
* steering head bearings
* swing arm bearings
* front brake system 
* rear brake system 
* tires
* carbs
* valve adjustment
* timing check

The only other thing I'd look at is to check the wiring harness for obvious damage or hacking/modifications, just to make sure there aren't any real obvious issues.

When that's done just ride it, warts and all, and see if it's a keeper.

When i bought my 1975 Z in 1984 i just ride it for one year and then shit happens and i had to do the pistons and valves. After that i refurbished the carbs and the bike runs great. Went on holidays to Italy and French (from the netherlands) In all those years until now i changed a lot on the bike but every part was like new when installed. Never problems but.. i never did the frame,  so this year November i disassembled the bike  to do the frame. After some bracing work it lays now at the powder coater. Althought the bike runs great i found several little thing to renew. You always find more than you think on those old bikes. So disassembling is a lot of work, start with the essential as DOHC already said and start riding the bike. And if you like it and want to restore it, go to your local bank for a loan because a Z is a beautiful but not cheap project
Good luck

This is bonafide gospel right here.
 

My tear down to the frame was necessary due to the bike sitting for so long, and being retired I didn't have an aggressive build schedule.  It took me 2-1/2 years before riding it the first time.  I immediately found small issues, and went right back to taking somethings apart to correct.  If it comes all the way down to the frame, and you are committed to finishing and riding it no matter how long/how much it takes, bracing is a good idea.  I did it to mine (KZ750) because I was already planning to powder coat it.  Getting the frame or suspension stiffer or handling better than stock at that point is kind of a no brainer.  Set some ownership goals, choose your path, and post away (with pics!).

This is great advice.  The main reason that I haven't put much effort in is largely due to me not having the title.  It just seemed like a big hassle.  The thought that this duplicate title is probably going to happen has me thinking about it more seriously now...

I wouldn't invest much into it until you have a clean title in hand.  Don't ask me how I know...
