'77 Yamaha RD400 "Jigsaw Puzzle"
« on: Apr 17, 2018, 17:01:39 »
So, I guess I'll finally start a build thread on this bike since things seem to be starting to happen... uh... more frequently.
This isn't my bike, but it's in the family. It belongs to my Bro, Matt.
Purchase date on her was Feb. 2015.
And this is how she arrived...



She was a roller and about 90% there. The motor had been removed and completely disassembled by the PO (actually by the PPO).
From there she sat in the corner of Matts garage while other projects and life got in the way.
About a year ago, she migrated over to my shop.

About 6mos ago, when I wasn't working on my own stuff, I slowly started assembly of the literal "bucket of bolts" that was the engine. This is where I nicknamed her Jigsaw Puzzle. With help of Corey (clem) and several online parts fiches, she started to take shape.




All new seals/gaskets were installed along the way, as was new ignition components and clutch.

And some parts that had deteriorated over the years.


She was complete and buttoned up about a month ago.

About three weeks ago Matt dropped off the carbs I made him clean. And Friday before last (4/6) I got the motor back into the frame.


Then Sunday (4/8) she returned to the land of the living.

Surprisingly, she fired on the first kick, ran smooth and crisp, and settled into a nice idle.

Now, with a running motor, all the fun can begin :)
As of last Saturday afternoon, she looks like this...



Frame, swingarm, and wheels will be off for powdercoat soon. New bearings, bushings, and tires will follow shortly after.
Everything will get cleaned, polished, and/or painted before being put back on the bike.
Plans are for a mild restomod right now. Low bars, rearsets, and a solo seat will be the main deviations from OEM for starters.
Then it'll be, Ride, Enjoy, and Modify as inspiration strikes.

Thanks :)
Neither of us thought to set up the video beforehand :o
She was running for over a minute before I said "Oh Shit! Lemme grab the camera!" :P
And since we just had to hear her run once more before teardown, here's a quick vid of her second fire.

Maybe watching this will teach me how to be a little more precise when I build.  Everything you do seems to be run over with a fine tooth comb.

Nice man. Glad to see that plastic bin is doing it's job. Lol
I need to let the PPO that you got that bike running again, he'll be stoked.
