Quick valve check question - I was at TDC, measured the valves and found they were all a little tight (about .02 to .04 all around). I proceeded to take the ACCT out, and then take the cam covers off. I used a zip tie to hold the chain up. I am about to put everything back together now, and noticed that the flywheel moved since I took the cams out and is no longer at TDC. On my other bikes (like KTM 990) I usually have a pin that locks the engine at TDC, but wasn't aware of that option here. My question: with the cams out, is it hard to spin the engine back to TDC by having someone hold the chain taut so that it doesn't get caught up? I had used a white marker to show which chain pin was on which cam tooth, can I just reassemble them that way, then spin the engine back to TDC and look at the cam marks to make sure? My only concern would be if the chain jumped the lower gear while hanging there on the zip line, which could make my white marks pointless, and could jam a valve into the piston?
