1981 Kawasaki KZ750 Resurrection

Carbs are done! Had an epic battle with the choke linkage. The spring is very weak and any slight amount of friction in the system causes the butterfly's to hang. Took a while but finally got it where I'm happy. The Keihin carbs are quite similar to the BS Mikuni's used on later GS bikes. Main differences are the choke and the Keihin's have a two stage main jet. Not sure how well they meter but I've read some reviews that say these 750's get pretty good fuel mileage - over 50 mpg. Fingers crossed on that anyway.

Jeez..those babies look brand new..w/o being over-the-top. Just the right amount of natural and shiny finishes. Beautiful restraint.
 
Was struggling to find a rear master that didn't have a pitted bore. Bought one off ebay that turned out to be junk. Found a decent looking one on ebay and sent a note asking the seller if they would be so kind as to open it up and look for corrosion. No response. Found another one and asked again. This time the seller came back with a personal note, and not only opened it up, he sent me some photos! Great service. In one of those small world moments the seller turned out to be our own Joe Whelan.:D Imagine that! Needless to say I bought it! Thanks again Joe!

My pleasure Ed ;)

I love how this forum works, when it's working well. Way to go Joe!
 
And you call me OCD... :rolleyes:


Hey Dale,

Most of the removable hardware and such were replated. Exception being the parts attached to the throttle butterfly valves, which look somewhat dingy, which bugs me. Really don't want to pull those things out though. OCD? Maybe just a little.:o

Ed, this is starting to look like your have some NOS stock of parts from the 80's you are pulling out and cleaning really really good.

Now I know I'm going to have to tear my ED completely a part (again) some time, but not sure how I'll even do this well.

Looks very very professional.
 
Rebuilt the petcock tonight. Bead blasted the body and replated the steel parts. Started working on it yesterday and couldn't find my bag of parts. Looked for it everywhere. It's kind of windy so started to wonder if the bag blew away. Looking around and found an empty bag on the side of the garage that looked like the right type. Hummm. Looking around under the trailer and found one of the parts! Ah ha! Kept looking and found the parts all scattered about. The fuel pick up tube found it's way right behind my cars tire! Good thing I found that bad boy. Unbelievable to find everything I needed. Thank heavens!:pray:

Wow just wow! luv those plated parts, what is the process?

Joe,

Caswell Plating sells a kit called "Copy Cad". Not cheap though. You can put together your own kit pretty easily only haven't found a proper electrolyte formula yet that replicates Caswell's. Search google on "home zinc plating" and you will get tons of hits.
 
Shopping for a rear sprocket. Z1 Enterprises is $29.48 + shipping. Can get one on ebay for $35 shipped. Just for kicks did a Google search and bang, Amazon is $24.44 shipped from one vendor or $25.75 from Amazon direct (2 day shipping upgrade with Prime). Can't beat that so placed the order. Never would have thought to shop for motorcycle parts on Amazon...

Don't know how pertinent this is but I had to replace a charger for my mp3 player and went to Amazon. The part came from one of their vendors from overseas somewhere, China I suspect and it did not fit. Would not work so I went through the process of getting a refund and long story short, it finally got back to me after about 3 weeks. Also took about 3 weeks to get the item to me.

Just sayin'. Check where Amazon products are coming from if you are concerned about quality or anything else.
 
Those are looking REALLY good.How do you get the plating black?Caswell chemicals?
 
Yes, Caswell's. Copy Cad kit, which is zinc. Also have blue, yellow, and black chromate dips. The blue is used on the bright parts.

The parts are not perfect but serviceable I think. Have been struggling to get consistent results. Those parts with the yellow cast need to go into the blue chromate. That removes the dark finish, but it also dulls the shine a little so it's a balancing act. Main focus was to remove the rust and put on a rust barrier. Zinc works pretty well for that, but not as good as cadmium like they used to use.
 
Very NICE Ed! Home/garage work. How much did the kit set you back?

I'd love to get a Caswell zinc plating kit but just to much for what I think I can do DIY.Might not be as nice as the old Cad plate but they look damned good to me:clap:
