Hey everyone, hoping you all can help me. My bike was in at the local shop because it hasn't run great since I've owned it. They did a leakdown test and said it was leaking a little bit. They suggested a valve check among other things. I paid for some of the work, but figured I should learn to do the valve check, so I read up on the HOW. The valve clearances all seem within spec, but I was having trouble finding TDC. Maybe I'm just missing something, but it seems out of whack. On the rear cylinder, when I rotate it through, it seems to come to TDC when the tooth with the X is about 1 tooth above the cylinder head surface. When it is 1 tooth above, I can feel the piston at TDC and the locking screw will go into place. When the X tooth is level with the cylinder head surface, the locking screw will not go into place. Also, I can barely get the X tooth to line up because it's on the verge of clicking over (not sure what does that). On the front cylinder, again based on using a screwdriver in the sparkplug hole and with the locking screw, it feels like it reaches TDC earlier than when the circle lines up with the cylinder head surface. I made these extremely amateur videos to try to show the issues. Sorry, it's hard to hold my phone, crank the engine, and hold a screwdriver. Thanks for all your help.
