Head to O-ring conversion
TZR125 Track Bike
The next step what I planned was to remove the head gasket and go to a O-ring conversion.
This will lower the squish from +/-1.35 to a +/-0.95mm
Like to measure what only this mode will do.

No damage can be found.

I did the cutting as slow a I could.

She is running again after the O-ring conversion.
Hope she is holding well so I can test the divergences

I also bound the exhaust in head resistance wrap in the hope it will hold the head better
Don't know if it will work, but at least it looks great
