you are riding without clips --- understandably ;-) 

may be you should try them! you would remove the effort of keeping your
legs up, and concentrate on steering instead.
 
Hallo Dirk,
I think your Baby-Python has nearly the same geometry then my bike (The
picture of your beautiful bike was one of the inspirations for my
project). I think the clips will also work with my bike ? I will test
it!!!
Thank you Dirk!

Interesting info. Good that you did not gave up!
 
I guess that what happened to you was quite similar to my experience
with the PX.5 one year ago. I made the BB-EOS 8 cm longer to adjust
it to my length and suddenly the bike was no longer rideable for
me (before it was ok).
 
The gravity center of the front part became too dominant/high and
the wheel flop effect started to overpower the self centering.
Resulting that I felt like sitting on a seesaw with the front part
moving from one side to the other. After I made the steering angle
10 degrees steeper the bike was normal again.
 
At the moment the steering angle of my bike is 60°. I can change the
angle very easy because of using the rod end bearings. I will test it!
 
Any geometry data of your bike available?
 
You have it on your project survey. Only the BB-seat-diff. is reduced
now to 15 cm.
 
With best regards 
Thorsten
