Yoshimura Racing Machines

As you may already know, Yoshimura was a leader in the famous Japanese motorcycle racing championships such as the TT-F1 and the TT-F3!
*At TT-F1 it was racing with a GSXR750


*At TT-F3 it was racing with a GSXR400 (~89)


Something you maybe don't know is that Yoshimura was also running a the Naked motorcycle championships such as the NK-1 and NK-4!
*At NK-1 it was racing with GSX1100S Katana


*At the NK-4 it was racing with a GSX400S Katana and....a BANDIT400 (93-94)!!!


Looking closer at the picture you can see many extra parts and changes.
Funny thing is that this exact motorcycle was for sale sometime ago for about 3000€ in a Japan sale!
What upgrades / parts do think was on it??

It was for sale in Japan as pictured!

Wow, vaya pepinaco!!

Joer, menudo basculante wapo y horquilla tocha... esa moto debe de ir de P.M. en circuito...

Gracias por el repor, Speedking.

No se que ha pasado con ella, pero estaban las piezas en venta en Yahoo Auctions la semana pasada (colin, estriberas...)

Ya solo quedan el escape (con el soporte artesano) y el radiador

I know cause i got the footpegs! Actually these rearsets are custom made by Yoshimura exclusively for that bike! Same goes to this exhaust and an oil breather tank (hidden under the driver's seat).
BTW that NK4 Bandit400 had the same MJN kit as you have @ivandit !!

You bought them? I was tempted but never decided to

Compraste las estriberas? Yo estuve tentado pero nunca me decidi

I decided right once i saw and realised the story of the bike!

Ahora esta en venta el motor tambien

Nothing is known for this engine but i would like to believe that has some head work  like porting , yoshi cams and maybe fcc clutch disks , if it is stock then nothing to go for..

I gave a try at the racing exhaust but didnt won :-(
On the other hand today the yoshi rearset arrived and i am happy about :-)


Traducción:

"No se sabe nada de este motor, pero me gustaría creer que tiene algunos trabajos de culata como válvulas, levas yoshi y tal vez discos de embrague FCC, si es de stock, entonces no hay nada que hacer.

Probé el escape de carreras pero no gané :-(
Por otro lado, hoy llegó el rearset de Yoshi y estoy feliz por ello."

Photos, photos!!

These are the racing carbs they were using. BST-MJN Type-B carb-kit was installed using MJ#125 , PJ#35 and MJN pos#3 (i think).

...and thats the oil breather tank they also used. Its was originally made for gsxr 600/750(if i recall right) so they modify it to fit on the Bandit400 racer

Traducción:

"... y ese es el tanque de ventilación de aceite que también usaron. Se hizo originalmente para gsxr 600/750 (si recuerdo bien), por lo que lo modificaron para que se ajuste al Bandit400 racer"

..and here's the carburettor heat shield (aluminium type)!

Traducción:

"... ¡y aquí está el escudo térmico del carburador (tipo de aluminio)!"

Puff... qué pasote de piezas!!

Esas si que son "Pata Negra".


Traducción:

"Black Leg".
