Well I made my intro post a little while back and have followed/read a number of build threads so I figured I better start one of my own for the current front burner project.

I picked up a new project a couple weekends ago. 72 CB450 that has been in storage for some 20 plus years. I have known of this bike for a number of years as I have been friends with the previous owner for close to a decade. I would see the bike when I visited him on the other side of the state. He had grand plans of rebuilding it and getting back into riding but he never got it done. He had had the bike in his garage for 18 or so years and it had been in storage for a few years before he acquired it. I guess he finally realized it needed to be in the hands of someone that would build it up. Since I happened to have something of similar value he really wanted in trade and a deal was struck and I made the trip to pick it up.

I got it stripped down somewhat in the first week or so and hope to pull the engine from the frame and get the rest of the suspension off within the next few weeks. At the moment I am only getting about two or so hours a week to work on it but that should pick up quickly.

Anyway my goal is to not cut up any stock parts since the bike is 100% complete. Some of the original parts are not usable without a fair bit of work and re-chrome. I will be cleaning up the stock bits and storing them. I am going to do a mild Street Tracker style look with it I think without cutting up the original bike. If I have to cut anything up it will be on ebay spare parts or stuff I fabricate myself.

On to the pictures to document the before.

Loaded up in the Truck to bring back to the shop. Some of these photos are not that great since all I had that day was a camera phone and funky lighting.





On the table in the shop going over what was ahead of me. Again somewhat crappy pictures, sorry.





Going over the spares and extra bits that were included in the deal. Spare set of carbs, spare ignition set with a relocating plate, spare finned cover, and all the original tool kit.







The start of the tear down process.





Stored parts on a pallet and waiting to sort, clean, refurbish.



More rust that I would like on the silencers.



More rust that I would like to see on the fenders.





More rust than I would like to see in the tank.





Much corrosion and oxidation on the painted aluminum parts and covers.

Well I finally got a few minutes to tackle one small project.

I wanted to do something different with the motor mount plates. No real reason other than I thought it would be a place I could have some creative fun with.

Here are the original front plates after a quick bead blast.



I found a few chunks of 1/4" 6061-T6 aluminum plate in the scrap pile so I machined some new plates. They look stock for now but I want to do something different with the finish. I am still deciding on polishing the aluminum, bead blasting and clear coating, or smoothing and anodizing them but that depends on the rest of the finish/color choices for the bike.

Now that the trial fit of these plates was a success I may also just make a second set with a different design to the center so they do not look so much like the stock.

The new set of front plates came in just under 0.6 pounds while the old steel plates were just over 1.3 pounds. So it did save nearly 3/4 of a pound but that was not the real point of this.

Test fitting the new plates.








New and old side by side.




I plan on making a new set of top plates and rear plates when I finalize my plans on the design and as my schedule allows.


Pics of the old plates.

Well I got some time today to do a bulk of the final break down on the bike. I had just planned to pull the motor and call it a day so I could sharpen a couple of lawnmower blades while in the shop but it was going so well I finished tearing down the entire thing. No more bike on a table. Now I have three pallets of parts stacked up on the rack.

Got the rear wheel and a few small bits pulled.



Motor is ready to pull.





Motor is out and on the cart.







Swingarm, centerstand, and rear brake levers off. Started breaking down the front end and got the controls off.





Some more of today's damage.



I was really unhappy with the condition of the front forks. This is the reason I really really hate rubber gaiters on forks. I think I can save these with cleaning, polishing, and elbow grease but I may or may not use them in the long run.








Now on to the bead blasting, stripping, cleaning, and decision making.

Looking real good Jason, you're really getting into it. Love the work you did on the engine plates, very clean work.

The forks on my 350 are in the same condition as yours, nasty. I haven't done anything with them yet.

Enjoying your work so far, keep it up.

Lookin goo so far! Looks like a good project bike to start with, most seem to have parts missing and are far worse off than yours! If you don't want that extra ignition switch that came in your deal and want to make a couple of bucks to put toward your project I'm needing one pretty bad! ;)

I think I actually have two so send me a PM and give me a few days to get back to the shop and dig out the spares box.

The bike was not intended to be a "project" bike since it had such low miles and original parts but it was not stored well so it lost a little of the value that it held. If it had been cleaned up before storage or stored better it would have been a real candidate for stock restoration. It would require a slew of NOS items to restore at this point so I am going to keep the original parts that are good in careful storage and use aftermarket/ebay/self fabricated parts to build a nice runner with a little creativity.
