That number suggests a 76 C model.

Hello, my frame no. on my white and red RD400 is 1A3- 331060. I guess that makes it an RD400F?



Cheers.

My father owned a Rd400 for more than 20 years, we are restoring it and confused about the engine serial number. The engine serial number is only 1A1 unlike the other rd400"s which has several numbers following the 1A1. Can you guys help us unravel this mystery that"s made us think for so many years.



Engine Serial Number: 1A1   (only)

What model is this specific rd400 built?

Could the engine be possibly the early model produced or the first one manufactured?

Frame Number: 1A1200489

Japanese imports  have the prefix only on the engine.

so could have been a import or replacment engine.

Well, I carefully read all post but still disoriented. Couple of years ago I found this beauty on a garage. I?m positive it?s one of the latest RD400 but I really can?t descipher if it?s an F or a G (no decals at all). Engine and frame number is "RD40082000196". Spoke wheels, tank shape and side covers look like an F or G. Cylinder heads an exhausts say "2R9". Any suggestions?



PD: Somebody told me it?s a 1982 "overseas" model, probably built with parts from an F and a G. Despite it runs (race?) very well with all systems working properly I will start restoration after your advice.



Thanks a lot.

Well its a 1979/80 RD 400 F or G, either the Canadian or Australasia version. As you said its a 2R9 motor and ppipes fitted to the Daytona Frame, dont worry Yamaha made em like that



Normally the frame No would start 3J7 for canada or 3M4 for australasia. Having the RD400 prefix on it may mean its a japanese market model.



the bike has been modified, indicators seat, front mudguard, the pipes look like the header and muffler have been welded together....but hey I bet thats a rare beastie in ecuador!

Thank you very much. I already found the original seat and front fender so I?ll set them up asap (looks weird tough) also chainguard not seen at photo. I think everything else is factory.



What should I do about decals? Daytona F or just G?



Thanks again.





PD: G ones usually got CDI right? Well, this one is points...

PD2: Exhausts are not welded (luck), just dirty.
