some modded xs400's

Different folks different strokes...I think he did a great job on making a café racer. That is what it is all about, and who knows maybe those big tires work well where he lives and races from cafe to café...Nice job Czech Guy, ride on..and thanks for sharing...I have to agree with xschris though, those carb filters are not going last long without some protection like using the lower half of the rear fender......Spad
 
Here is one with some thought put in it.

I really like the look of that one. I could take or leave the gimmicky parts (brown spokes, patina tank, etc.) but I love the seat, the overall stance and how the 750 tank looks on it.
 
Some xs360 stuff. Also found a dyno sheet for the xs360. Not sure how accurate it is because it says it has a 8.7:1 compression engine and yamaha states it's 9.6:1:shrug:

They sure had some fancy computers in 1976! that graph/sheet looks too good to be from the era. Red on sepia tone? I figured back then they'd just be printing out data as raw numbers if anything or maybe not printing graphs at all, let alone in color.
 
I'am sure it's not the actual data sheet:laugh: It's a write up in a bike mag from back in the day.
