ON my 2009 r1200r, finding TDC has been a challenge. That arrow that shows up so well in pictures doesn't show up so hot in real life on mine. It's there, barely visible, but it is almost a 2 person job. I tried putting a dot of paint on it, but the paint was washed off by oil. It certainly does not jump out at you.
Two questions: are there any tricks to getting TDC, other than turn the rear wheel a little, look and feel the valves, repeat...
Can you assume the engine is TDC IF BOTH valves, exhaust and intake are loose. IOW, once any clearance is there, is the engine at TDC? It seems that they are either loose or they're not, no middle ground.
