Just picked up a 2009 KTM XCF (dual cam of course) 450 and need to check valves. For a company which has amazing bikes and engineering, their service manuals are absolute garbage, worthless. I cannot find TDC, after 30 mins of turning the crank end and sticking a zip tie in the spark plug hole and looking for the mark on the cam chain gear. A few questions which may help you help me. 1. To find TDC should I be rotating the wheel forward or the crankshaft bolt counterclock wise...correct? 2. The 6mm bolt that is supposed to hold engine in TDC from the hole in the lower front of the engine: how far in is it supposed to thread in once I got it at TDC? (I can get it to thread all the way in until it keeps spinning but it doesn't stop or engage anything.) 3. When I'm at TDC are the cam lobes on both cams supposed to be facing away from eachother or towards eachother or directly up? 4. As mentioned my cam chain gear has just one indented mark on it. Whenever I get it to the top, where one would assume the engine should be close to TDC; the ziptie is never at it's highest and the cam lobes are neither facing directly at eachother or directly away from eachother! I know, I know I could be on the wrong stroke but I've turned that engine over a hundred times and I can't get anything to line up: If I get the cam chain gear mark on top, the zip tie isn't at it's peak or the lobes are facing every which way or vice versa. I'm stumped. I ended up just turning until I got the intake cam lobes facing straight up. Then check intake clearances. Then I turned until I got the exhaust cam lobes straight up, and checked the exhaust clearances. But I'd sure like to know how to get it to TDC so I can take the cams out and replace shims.
