Our friend George donated these old manuals to the shop last week. I really like the graphic design and photography in these old things. How cool is this dude’s helmet!
Woah… FULL color!

Ricky picked up these 2 motorcycle textbooks that were printed in the 70′s. We’ve been nerding out on the ton of info and diagrams that’s in these books. They cover everything from tune ups to rebuilds for Honda, Harley, Montesa, Ossa, Norton…
Each of these diagrams would have been drafted by hand.

So, I’m still working on the seat for the cb650. This is my first time working with metal since high-school metal shop. So, it’s been a while. I’m pretty much winging it. Below are my steps for figuring out what I’m doing and how I’m doing it. So far it’s turning out real good. I’m ready to start cleaning edges up, make some bends, and then welding I guess.
1) Photoshop it out
2) Template it out
3) Plan it out
4) Draw it out
5) Cut it out
6) Check it out
The tank on my 550 looks clean from the outside but it had a lot of crusty rust inside. I’ve used muriatic acid to clean tanks before but I wanted to try another method. So, I talked to my buddy Ryan who is a material scientist of sorts for a living and he gave me the run down of how to do electrolysis to remove rust.
Supplies:
salt
metal
water
electrical tape
DC power
Tape the petcock shut.
Dilute roughly 2 cups of salt in water and pour it in the tank and continue filling the tank until it’s almost full.
Connect the positive to the tank and the negative to the metal bar and cook it between 6 AMPs and 8 AMPs for 30 to 45 minutes. If it’s too low in AMP’s add more salt and if it’s too much dilute the mixture.
This process worked great for removing the chunky rust so I suggest doing this and then a quick acid wash to finish the job.

Here is an alternative way to produce a tail section for your bike with a minimal amount of tools and about $50 worth of material.
Materials needed: Epoxy Resin, Fiberglass resin, Fiberglass cloth, Sandpaper in varying grits, Paint and Primer, Painters tape, Aluminum tape or Tin foil (The tape is better and more expensive. Don’t let the Jankeys see it, or they’ll scrap it!), Drop cloth, and Floor wax, Cardboard, and Something to create the overall shape of your tail. i.e. shapeable foam, clay, the rear section of a gas tank, an old KZ tail, a salad bowl, or a mailbox.
Here is the site I used to get a better understanding of what is involved. It has pictures and step by steps to build yourself a killer custom chopper seat pan. http://www.jeffreyphipps.com/seat_pans.htm
Do the glassing neatly, in that I mean, no bumps or air bubbles. This will make your sanding and filling time later less annoying.
For the true grit hicksters
