Hello Everyone, long time no post, however I didn't want to post until I had a bike to actually contribute some information and pictures with. So my bike is a 1984 Yamaha XS400 Seca, my wife and in laws bought it for me for my birthday last year in 2015. Over the winter I had worked on it, and got it kind of wrapped up for now last summer so that I could ride. I have posted some pictures before, but I wanted to make an album and actual post everything I've done. So far this is what I have completed....
- Getting the bike back into a running and road worthy condition. This involved removing the carbs and putting them in an ultrasonic cleaning to clean them out, and replacing the
o-rings between carb bowls to stop the left bank from running leaner than the right. Built a simplistic carb balancer out of two beer bottles and some clear tubing. Balanced the carbs.
bike starts like a dream. Running the bike on 100LL aviation gas as I have an unlimited supply at work.
- Disassembling the bike, repainting the body paneling from purply pink to a British Racing green colour. Bondo existing Yamaha bracket screw mounts and sand. Need to get the tank repainted,
but it will do for the time being. Applied a carbon fiber decal as tank knee pads.
- Repainted the frame black. Repainted the forks black. Rebuilt and repainted the brake caliper. Disassembled rear fender and removed uneeded plastic, and glass blast and powder coat the
rear fender, grab handles for passengers, engine support mounts. Clean and polish rims, clean engine.
- Install clip on handlebars, changed the geometery of the headlight for the time being making custom aluminum brackets.
- Removed cable tachometer, built a plug for tachometer cable, and installed electronic tach.
- Installed two pod style chrome gauges. Reupholstered the seat with black leather.
- Changed indicator lighting system to a custom built LED panel, built top aluminum fascia for it (powder coated black and labelled).
Overall, happy with the way the bike has turned out so far. Definitely over the winter I am going to be focusing more on the engine. Pulling left and right engine and transmission covers
and will be painting them in crinkle finish paint. Replacing all hardware with hex head new stainless screws. Brighten up the engine with alumiprep.
