TZR125 4DL Specials

Slowly getting started with the Special engine.
As I'm still 3MA minded, its no more than logical to mound a 3MA cylinder on a 4DL engine.

Roughly the plan is:
1) 3Ma cylinder a 4DL engine
2) bigger reedblock
3) dry clutch
4) home made ignition

First impression is good

Bore/stroke are the same
No changes need to be made at the cylinder
Piston on lowest point, all is good

Lowest stud's are good, just need to machine the lowest mounting holes on the cylinder by 1mm
The top two stud's need to be replaced
