Pagina Tzr 125 3MA cilinder
Need to reshape the crank case to mach the 3MA cylinder
Sadly I didn't take many pictures, but here is started
After some hours grinding I ended here
Made sure the flow uses the whole port
Here you can see the differences
Typical thing is the cases are not symmetrical.
As you can see sometimes I grind something that shouldn't be grind but as I'm a amateur so it will be OK.
Next step will be to make them more equally to each other
