I'm still working on this build. I've been trying to find a good welder and nobody wants to do this type of work. I'm not a welder and this has stalled me since the winter. About 3 weeks ago I went out for a ride on my MT10 and 2 minutes out I spotted a cafe racer and I followed him to an ice cream parlor right down the road. I introduced myself and was checking out his build which was a Kawasaki 250 cafe racer that was a seriously cool budget build. What made it so cool was that he did a bunch of custom fabricating which was beautiful quality. I asked if he welds and said yes, he has a small hobby motorcycle business. A couple of days later I brought my frame over to his little shop which is called Lizzie's Choppers - He lives 2 doors away from the LIzzie Borden murder house.


I told him my plan, what I had fabricated and what needed to be welded. Not only did he weld, but made suggestions and improvements. It is so cool getting to work with someone like this. This is the only part of this project I couldn't control and it's exceeding my hopes and expectations. He also has no head for business so I had to insist on paying him almost double what he asked. It's a matter of respect and doing the right thing. He's also somebody that I can learn from and generally pretty cool to hang out with.


In the mean time, I have been doing stuff also. I'll be picking it up in the next day or so and now finally begin to put it together and test fit everything. My motor, wheels, forks, swing arm are all finished and ready to install. Once I get it all fit up, I'll take it apart and send the frame to my powder coater. It's satisfying to realize that the grunt work is behind me. Assembly is generally pretty easy on these bikes when you do the grunt work well.


I'll post some pictures of the frame when I pick it up. It won't show well in pictures until it gets sand blasted and powder coated but it's excellent prep and fabrication. Hopefully with the easily over $8000 in parts I have to hang on the frame , it'll look like something.

Here is the frame ready for finish sanding and then test assembly. It looks a little rough because it's unfinished but it's some nice fabrication. The tail section is restored back to stock to work with the tracker seat. All of the electronics and battery will fit in the trays which will leave the center section completely empty. I made a plate to go in the section where the lower fender would be. Not an original idea as I've seen it done on other builds. It will keep the pods dry if I get caught in the rain and it looks pretty cool.

You’re going to want to seal the entire seam of that electronics tray to prevent any moisture from getting in. The rear wheel will be flinging it into any orifice and the smallest gap.

Ideally, your welder would have run his bead on the underside, outside corners the entire length. He could have done so without filler and made a watertight seal, and eliminated the welds inside. That's not a knock against him at all. This is merely "experience" speaking on welding up these types of things, especially with a motorsport orientation.

I was actually going to do my last project in nickel and the quote even seemed rather reasonable for what is involved in the process, But... After calculating in the hours required to properly prep the frame to get a nice smooth homogeneous finish, it tipped into the realm of ridiculou$.  =/

Just read this and curious what the total was for bright nickel? I want to have my Rickman CR750 replated but not sure I actually trust anyone I have talked with!

At the time (2019) I was quoted about $600 to $650. (not including swingarm) Though Prices for everything has shot up a great deal since then, so I would expect it to be substantially more now...?

I saw my first Rickman at Slager Forbes motorcycle dealership in NJ around 1970. I never forgot how gorgeous those nickle plated frames where. I was originally thinking of doing a faux nickle powder coat but they just don't look the same.

I bought a tube sander. Hopefully it saves time and work.

One of my main goals was to upgrade the suspension to closer to modern standards. I've lost about 40 lbs since I started this build and when I ordered all of the suspension stuff, I ordered with springs for a 250 lb rider. I realized that this thing will be terrible to ride now and had to bite the bullet and buy new springs which i did. Can't make an improperly sprung bike handle. No way to set sag when the weight is that far off.

Hopefully you calculated rider weight fully outfitted? And changing the weight of the fork oil can have an impact on rebound. Stock forks had no preload factored in short of installing spacers beneath the caps.

Personally, unless the forks and shock are fully adjustable, they are crap in my book. May not be vintage accurate, but I’ll take great handling and safer riding over aesthetics all day.

I installed fork caps with preload adjusters. It's easy to add or remove oil to change rebound and compression to a degree or go up or down in oil weight. I got a lot of feedback from Race Tech on setting up. I want to keep the stock look and I think this is as good as it can be. I'm not a fan of putting upside down forks and changing over to a single shock rear. I want a unique 77 CB550 but that still is recognizable as one.

Those are nice. Dual rear shocks work fine as long as they are good quality and fully adjustable. Wilburs makes a very nice set of road shocks that tick all the boxes.

The fork caps are very good quality. There are some cheap ones on Ebay that look similar but are junk. I know Wilburs have a good reputation but I haven't seen anyone that carries them. I went with Hagons which were about about $450 with the spring rate I wanted. I can't see investing too much more than that on a 50 HP motorcycle that isn't going to be my daily rider.

I'm making progress. Doing a mock up and I've got it rolling. I've been working on motorcycles since I was a kid and there are still so many things to figure out. I bought this a s a basket case and don't have the advantage of taking it apart and seeing how it goes back together. Thank God for forums, YouTube and having a 77 Honda parts book.

This is what I've accomplished so far this summer:

I bought a universal seat / fender from a European company. I was trying to figure out how to mount it and found Tuffside seats and was looking to see how they do it. I was so impressed with his process that I bought his version which is CB550 specific. It's real nice quality.   

I got the from forks and wheel installed and the front wheel was totally bound up. I'm doing dual discs and a speedo delete as I'm going with the Motogadget speed sensor. It's a little tricky because the speedo blank out part is designed to work with the mechanical speedo base. I also tried turning the forks around so the calipers face the rear. I ended up calling Jeff from Godferry's Garage and he diagnosed the bound up wheel on the phone. He explained why the front side install was the better way and so I swapped it back and problem solved. I also got a master cylinder set up from him that is way cool. I'm very appreciative of his help and guidance.

I also picked up a set of Rox risers so my handlebars will clear the preload fork caps. Borrowed a couple of sets of handlebars to see how they look and feel and then bought a set of Renthals. Since I have all Motogadget controls, I needed to buy a throttle. There aren't a lot of choices for a simple pull style and I didn't want a Chinese piece. I settled on a Domino and it will work with the Murrays Carb cable.

I had bought a set of Cognito rear sets. I called them and asked if they would work on an F model and they explained that I had to modify it and get a pivot from a K. Apparently I wasn't clear on that my 550 is a 77. They only work up to 76 which I found out when trying to install them. (If anyone is looking for a set, message me. I also have a tracker seat. Both brand new) This really sucked as I hate the way the stock pegs look. I
took a shot and bought a set of 98 Yamaha YZ 125 - 250 steel pegs. As it turns out, it's a simple modification. Grind about a quarter inch of the the tube that the pin goes through, Get a grade 8 or better 3/8" bolt and make the mounting hole a little larger and they fit nicely and look pretty cool.

I have a few frame mods that I didn't account for. Nothing terribly difficult but they have to be done. I thought a lithium battery would fit in the tray under the seat but no such luck. I'm going to take Cal's advice and put a battery box above the swingarm pivot. I haven't investigated what the best way to do that is. I'm wondering if it needs to totally enclose the battery and hoping I can find one prefabbed. Any advice is welcome.

My painter lives here in Massachusetts from May to September and the Florida in the winter so I had to get my seat, front fender and tank over to him. He does custom motorcycle paint and I had to rush as I don't want a non motorcycle guy to do the paint. It's a bit premature but they are all test fitted.

The guy that does my welding now is a good fabricator and we've become friends. I had bought a brand new sand blasting cabinet and compressor from a guy that decided he wasn't going to use them for $200. When I got them home I realized I don't have the space for the cabinet and traded it to my welder for the rest of the work I need. Worked out pretty well.

That's pretty much where I'm at. I'm hoping to get the frame done and over to the powder coated by the end of September. We'll see....the road to hell is paved with good intentions. Mostly I'm really enjoying the process. 
Below are some pictures.

I think the gas tank I have is from another year K as it has the clips for the chrome trim on the bottom and I don't think the F model had that. I bought a new petcock for it and it doesn't fit. The nut is too small for the fitting. I've spent a considerable amount of time trying to figure out which one it is and apparently there a few different tanks that Honda used. My painter has the tank so I can't measure the fixture. This tank has no overflow or vent tubes if that helps. I could use some help.

Which was the first suggestion. Swing arm install was an alternate.

Cognito makes trays in varying depths. Or, you can have one made for you via SendCutSend.com. Draw it up, send it along, they’ll process it (with bends and holes) and ship it back to you ready to go.
