If my memory serves me right, from my time on Okinawa in the late 60’s, that Japanese text is the lyrics to In-A-Gadda-Da-Vida. I could be wrong. Ed

kano is the man! :woohoo:
thanks for the help bro!
who cares what it says,the pictures speak for themselves:P .
japanese doesn't translate to english very clearly,it ends up sounding all philosophical.which isn't a bad thing,but i am one of those people that can figure out more by looking than listening to descriptions.then if i get hung up,i look for the words.hehe.
i really liked these pics because being welded with the bronze makes the gussets easier to see.
happy to share,hope folks get some ideas/inspiration.

I'll translate, my bike has a Japanese word I put there myself so obviously I can speek Japanese.

Page 1:

These bikes are very fast and scary without proper frame structure to carry the loads imposed by the rigors of high speed riding and handling.

John here is a master frame builder with over 50 years of experience who thinks the most important part is getting the pieces to flow together and agree in a harmony of strength and the proper flexability needed to produce a world class bike.

Page 2:

This old frame has been braced with light weight chromoly tubing and gussets to produce better handling in both street riding and aggressive racing conditions.

(Inset) Jimmy loves his new frame and has commented the color matches his racing leathers well. Also he has gone from sliding out of the first corner at every race to finishing first at every race. If he had one thing to say it would be "thanks John".

Page 3:

Make your frame look like this and you can be a winner like Jimmy or gainfully employed like John. Also John would like everone to remember not to weld directly to the frame as the bracing must be forged in to achieve the proper balance and harmony necessary to extract the most performance out of bike that is 30 years ahead of its American and European counterparts.



Seriously thats all it says. Sure it looks longer, but thats only due to inefficiencies in translating the words in such a way that most moto-mag readers can understand it.

Thanks again to Kano for getting these up. I might need to re-powder my frame now as I would like to go back through my frame and tighten it up a bit.

Interesting that they say:

"remember not to weld directly to the frame as the bracing must be forged in"

What exactly are they trying to state? Maybe, they are afraid that if people weld the frame will twist? Most don't have a frame jig to use to keep the frame from twisting while welding.

I dunno, but they've always had a great reverence for steel and its properties.

I believe they are refering to heat treating the final frame. If you weld without heat treating the metal is brittle at the weld and additional stresses are introduced into the metal. This leads to twisting if the stresses are high enough compared to the strength of the frame.

all this info and it seems no one bothers doing it to a 650 frame. this becuase the 650 dont haev the power to twist the frame? also the 650 frame seems to have a slightly differant frame to the one above.
cheers rob
