My 95 KTM 300 has started up in reverse a couple times, so I decided to check the timing. The bike does have the SEM ignition. The manual says 13 degrees (1.2mm) BTDC. I found TDC with my dial gauge. The problem I'm running into is that once the flywheel is rotated clockwise and pinned to the stator, I can't get 13 degrees of rotation. My dial gauge is in inches so I need .047". I'm can only retard the timing .02". What am I missing/not understanding? Please help.
