Currently putting a DS1000 engine into a 900 frame.
I noticed that when the timing marks on the cam pulleys and the scribed mark
on the clutch case are aligned, the pointer in the timing window ( left side) doesn't line up with the TDC mark
on the rotor and the front piston comes up short by nearly 9 degrees of crank rotation.
is the timing mark on the layshaft pulley out or do the cam pulley timing marks not align with TDC?

the mark on the timing pulley is an indicator of timing shaft position. it's not a tdc mark of any accuracy.
Sorry I dug up an old thread but... Phew! I’m just about to check my valve clearances and found that the TDC reference marks on the cam belt pulleys did not co-inside with any of the “TDC” marks in the timing window. Had me confused/slightly worried. On with the job then...

Further to above, after checking again more closely, my timing window TDC marks did sync up with the pulley marks.
