Starting on my 73 RD 350
« on: June 12, 2020, 04:40:28 AM »

I started the restoration on my original 1973 Yamaha RD 350. I acquired this completely running example from the famous "Buzz Walneck." I will take it to a level 2+ restoration and it will be done corectly using OEM/NOS and new 70's level chrome, (No "Harley show chrome") and do all the re-zincing of the original fasteners myself. The engine will be refreshed down to the crank. All wiring will be scrutinized and any replacement I have the tools and parts to use only original style Japanese connectors and wire. This will be a fun project as my 74 Suzuki GT750 was completed last week and I have been waiting to dive into this one. I will update this board on the progress.

The 73 RD 350 is coming along nicely. Things done are:

-Frame and other bits back from powder coating. Look great.

-Crank specs are well within tolerance.

-inner engine case vapor blasted and engine partial assembled.

-New wire harness arrived.

-2 shipments of OEM Yamaha parts arrived from Partzillia.

-All new pistons, rings, bearing and all seals ready to go in.

-Honed and finished the barrels and had heads vapor blasted. All painted and polished in house.

-Wheels polished, new spokes going on vaporblastred hubs, (*Yes, I true my own wheels.)

I am sure there is more but for now, it is going good.





Parts to send to chromer and some polish at home.







*All done in house:






Before...UGH!

It is coming together nicely
A vapour cleaned engine makes such a difference.

Yes, very nice.  It is good to see an "OE" resto in the USA and not another gee-whizz souped-up bike. Well done!  :)

Shiny bits...

Shiny time. The parts came back from the chrome shop and they look great. Still have the rims and one fender coming next week. I should have the engine done this week and the wheels laced by a week from now. Steady pace.

I did the fork lowers yesterday. Thank goodness for my Caswell buffing station. LOTS of hand sanding, ugh! But they look nice.

Will you be lacquering the fork legs or leaving them au naturale?

I don't like lacquer because it over time it becomes a issue to deal with. I use CTI metal polish to make em shine and fill the pores then I spray them with "Boeshield" and call it good.

Wheels n such.....

More progress on the 1973 Yamaha RD350. Wheels trued with new spokes and new chrome. A tedious task but with a spoke torque wrench and digital gauge, it makes it so much easier to fine tune beyond what is practical.
