Valves Job - lots of questions
1. do i have to remove the engine bolts on the right side to take off the cylinder head cover as the manual says? won't that remove the engine from the frame and make it a pain to put it back?

I can't speak for the new-gen bikes, but on my pre-gen the bolt you are talking about won't make the engine loose or come out of the frame.
If you haven't already came across this link, here's a good DIY on it with lots of pictures: http://www.theyeagergroup.com/2008_n..._clearance.htm |

Thanks for the link. Better pictures than the manual.
~~~~ Q2. I'm trying to find top dead centre. I've been through several rotations of the camshaft. When the lines on the sprockets align like in this picture (http://www.theyeagergroup.com/2008%2...t/DSCN0951.JPG), I see a mark on the timing inspection hole. BUT, the cam lobes are not pointing away from each other at this point. The EX is pointing almost straight up. And the IN is just about done pressing down on the valve lifter. They are NOT facing away from each other then the sprocket marks match up. So, technically TOP DEAD CENTRE is when the lobes are facing away from each other right? |

okay. when the timing hole shows 1T, the cams are positioned as they should be (facing away from each other) for the left most valves. should i just go ahead and measure from here?

Another Q.
if the clearance between the cam lobe and the valve lifter is tighter than allowable range, I'd replace the existing shim with one of a small size, right? |

I did. Tho a lot of it only started to make sense after I started doing it on my own. Reading it before doing the job itself didn't really cut it.
