I've hit a snag with my 01 fe650. I had the bike running well with new stator, cam , auto decomp DSVK del Orto refresh . I took the timing side apart to fix the sprague and sledge. Now, I can't seem to get it to go again. It used to start on the button, but now it turns over then hits compression and stops dead. I've checked timing, motor at TDC, cam lobes up, flywheel timing mark lines up with bolt hole. Valves adjusted four times now. Lots of spark. Been through most things three times. Tonight I pulled the cam cover to see if the adc spring was broken and it was good. It doesn't feel wound super tight but, the clog does snap back. does anyone have any suggestions or thought?
