Hi everyone,

Distance from engine cover support at head, to flywheel, is 136mm.
Diameter of flywheel is 207mm.
Distance from engine cover support at head, to centre-line of shaft, is 240mm.
Distance from engine cover support near dipstick, to centre-line of shaft, is 129mm.
Distance from engine cover support near throttle plate, to centre-line of shaft, is 134mm.
Distance from the air filter lid to centre-line of shaft, is 137mm.
The head has “25” stamped into the bottom corner, nearest the fuel tank.
The flywheel is stamped with “82” and “OIM”.
The engine has “062” stamped on the top surface, between the flywheel and air filter.

I have estimated that the engine cover should measure 368mm, from the inside face of the straight end, to the inside face of the furthest point on the curved section.

Regards, Ross.
