Note the info “Timing marks”

Each tooth on the flywheel is = to 3.75 degrees SO 9 teeth back from TDC is where you need to be well worth keeping this info

This may also help to find the timing marks

This info may help

On big block Guzzi the timing marks should be thus

The TDC mark Right hand Cylinder (Just above the D mark on the flywheel)  
Distance to the Static mark is 4mm  
Static mark to Full advance mark is 62mm  
D Full advance to the arrow (which is the alighment arow is 24mm  
The S (Left hand full advance to the D Topdeadcentre mark is 114 mm

For the 850T Le Mans 1-V Big Valve Cali 3 & 1000S these marks are:-

TDC-Static 16mm  
Static-Full Advance 52mm  
D-arrow 22mm  
S full adv- D tdc 112mm

For V7 Sport,750S,earlyS3

DTDC-Static 26mm  
Static-Full advance 52mm  
D full to arrow 12mm  
SFull advance-DTDC 102mm

Hope this helps

Yup follow the above from D top dead centre, the static mark needs only to be a mark the Full Advance is the one that you use the strobe on.
