2013 Tc-250r Engine Problems

My son gave his bike to the local shop and they got it running. The mechanic said that we had installed the cams 180 out, that the alignment dots were next to each other instead of lining up on the top of the head on the outside of each cam gear. I know for a fact that when I put it together I had the timing marks lined up exactly as in the shop manual, the piston at TDC with the dots on the outside. I attached the page of the manual that we used, and we set the timing exactly as in the diagram. I don't know how that changed, but the bike is running fine now. Thanks to everyone for their suggestions!

My first rebuild was an old 72 cb 350. I installed my cams the same way and could not get it running so had a local shop do it right.
