    First build, 1977 GS550

    This is the project as it sits to date. Once the seat is done, its only shocks and paint, then its pretty much wrapped up. Today I have more time than money or ambition so on the internet the project goes. I'd love to hear what you guys think! Kevin

    And that engine.... It had equal compression on all 4 cylinders. 100 psi. After the carbs were rebuilt, it actually ran pretty good. But, it leaked oil almost as bad as the carbs leaked gas. So a tear down was in order. While I was at it, pull the rings, hone the cylinders. Check all the...

    This is the rolling chassis to date, the motor is ready to go in, but I'm waiting to have the seat upholstered. Its going to require taking the bike to the shop so the seat to tank transition can be done how I want, and if I put the engine in, why push the extra weight into the back of the truck?

    Finally, done welding and grinding and sanding and blah blah blah to the frame!

    And the seat pan. Rubber bushings between the cowl and frame, can stand on the seat and no weight is transferred to the fiberglass. What do you guys think?

    These wheels were a bit tough to get trued. They are steel, and the weld is, well, not exactly as well finished as an aluminum excel that I'm used too. Got the runout to a few thousands, will all change after the first pothole anyways. So tempting to buy new hoops, but they were straight, and...

    Paint and polish!

    Now it was on to the wheels. The spokes were pretty pitted, was on the fence on weather to strip them down and cerekote them or buy new ones and be done with it. Once the tires were removed and I saw the nipples, there was no question, they were too corroded to salvage. Now, the big question...

    And a seat pan. I'm sure there are easier and shorter ways around this barn, this seemed the most logical at this point. My main focus was to not have the cowl bear any weight, floating between the seat and frame, maybe its overkill or I didn't trust the fiberglass not to crack. I really want...

    Soaking the carburetors in Pine sole and water over night works like magic, still blown away at how well it works.

    Now its starting to take shape, I'm no artist so making things from scratch like this usually results in several attempts to get the final product to look like the idea in my head, but this one I got lucky. Still at this point not figured out how its going to be mounted, but hey, full speed ahead!

    Once the wiring was completed, sorry, didn't take any final pictures of that yet. I was able to fire it up. It ran, rather poorly, the carburetors were leaking gas like crazy, they needed to be cleaned and rebuilt, but on with the project. Watched a youtube video from Dimecity cycles on how...

    Now, I'm sure with enough time and patience, a guy could make sense of the stock wiring... The copy of the diagram that was in the manual was more than difficult to read, plus the stock connectors were giving readings anywhere from .1 to 100 ohms. Not good. And to top it off, the goofy, in my...

    McMasters is an awesome company! I needed a .001 type clearance from bushing to pivot point, the controls I bought were around .006 ish, a little cutting and welding later... Plus they needed to be spaced out from the frame an inch or so. Much better now, the rear brake was more of a pain.

    At this point, believe it or not, it still had not run! Not even tried too, figured that would be the easy part, since it had compression, but that was getting to be the focus. The foot controls were not really turning out how I wanted, the bushings were not a tight fit, they had too much...

    And yes, Renthal bars, motocross is my main passion/ hobby, seemed silly to have anything else.

    There were about 4 different versions of the battery/ electrical component mounts made, I'd dream one up over a week, build it, then have a better idea a week later. Repeat... But as a bonus, some of the parts were showing up, originally I wanted to do an electronic speedo, with tack and make...

    I wish more pictures were taken at this point, if I was a better fabricator it would have been a heck of a lot less grinding and sanding. Was about a two day process to get this how I wanted. But its done now and good enough for me!
