I am trying to help my son finish the rebuild of his '09 YZ250F. The prior owner blew up and repaired the clutch, but didn't bother to clean all the debris out of the crankcase. A very bad rod bearing was the result. It now has a new crank, piston/cylinder, balancer bearings etc. The reassembly has gone well until I got ready to time the cams. It appears that the prior owner installed an adjustable cam sprocket on the intake side. It doesn't match the pictures in the shop manual. The above picture (if it loads correctly) shows the current timing at TDC. There are 2 dots which I have aligned with the top of the head, and another dot which is straight up at 12 o'clock. Does that look right to you guys? The lobes look to be in approximately the correct position and there is no valve to piston contact turning it over by hand. Thanks for any help you can provide.
