Yamaha RD 250-350-400/TD3-TR3 topic.

[Jamathi]

Better start a slightly older model Yamaha topic here.
It is clear a few of our members are in the process of building/restoring these trend setters.
PLEASE DO POST PICTURES OF THESE AIRCOOLED YAMAHA'S!
Lots of the newer generation never seen these aircooled beauties
Still to be found in sheds and garages all over the countrieside!

If you do have one that is in the way, I and some others will gladly take it away to be restored back to being used/driven again!
These, 1971-2-3 were the day's that a production race bikelike this

was directly based on a road version that anyone with the $$ could buy and succesfully compete in international-national racing!

[smoker]

Gotta get going on my ones...damaged myself at christmas and haven't done a thing. The TR is just such a lovely thing. Well finger is coming out!!

Anyone doing expansion chambers??

Got a set of crossover TZ350G's that I want copied in thin mild.

Like these

[Jamathi]

Here a picture I found of Barry Sheene on the French importers sponsored (Sonauto) TD3 250cc aircooled twin cilinder Yamaha around 1972-3 just before he went to Suzuki!
One of his team mates was Jarno Saarinen

The kinda thing I hope to end with, and what I'm starting from

[Jamathi]

What else have you got?
Engine, wheels, forks, exhausts, ignition, fairing?
The frame you have, what is it ?(the stamping on the head tells you, first cluster like 351 =RD350 )
It is a roadbike frame and the footpegs plate can be cut of.
Nothing wrong with a roadframe by the way!

I am in a similar boat and need to find more parts along the way.
This is also a roadframe of a RD350B modded with the 9'

[Jamathi]

Here is someone who has gone the other way and made a cafe racer out of a real race bike!

[smoker]

Mines an RD400C frame (76) which I'm paring back as a TZ350A replica. Thought about doing an aircooled replica (TR) but will most likely use a water top. Also building a H model copy from a RZ frame and motor with Banshee top end and total loss ignition.

What stuff you looking for?

On the RZ based bike I'm thinking of using a set of 28mm flatslides I have with my genuine G model pipes (or copies if I can get them) with Electrex ignition.

On the 400 framed bike it will be a set of Gibson pipes if I can't get copies with 28 or 34mm roundslides and Femsa ignition (total loss).

Ignition (total loss), rims, rear shocks and front fork/brake caliper.

Fairing ha arived, sadly not the seat.
Pipes are now wanted so that the fairing can be fitted propperly.

[Jamathi]

This bike without an engine!! just sold on fleabay for,.... wait for it,................... $6099!
That is just out of this world!!
If it would have had an engine that was matching the numbers , but no, No engine and no history known!!

[Ric]

That front hub is worth about 3,000 on its own.

Yep and the rear is not far off either, tank about 1k if good and frame with unbroken fairing mounts also not cheap. A lot of this stuff can be sourced from France and Holland, the prices will make your hair stand on end.

Great to see a 250 coffin tank and looks a very good job you have done with it.

Trevor Discombe at the Hamilton Road Races in 1978 or maybe 9 my (Ex) wife took the pic as she went I was working. I think it was a TZ700 from memory which is fading.



My production race/ ride to work bike RD 350 Pukekohe NZ Castrol One Hour Production Race tuned by Trevor Discombe

[Jamathi]

Well a bit of an update is in order.
Made the Pipes fit inside the fairing so the bottom belly pan can be used.


Bought propper wheels from a fellow PSBer, Thank you very much and mucked about with other bits to get it to this state, whereby the fairing stay's will be made and welded into position.





Fairing sits just loose and will fit better when all the bits are in place.
So far so good, now the decision which colourscheme to choose.

The Don Emde Daytona winner scheme?

Kenny Roberts Yamaha USA scheme

The traditional production colour scheme?
The rear seat is an old genuine Daytona seat of the era, which I like better than the proddy unit.

donny Vesco seat looks the goods Bert and the wheels came up well, nice work
