so i finally got the valve cover off today(PITA)and i checked the valves and could not see a timing mark to line up down low where you take the plugs out so i just lined up the two marks on the cams thinking that this would work also....well the intake were all .1 to tight and the exhaust were more than .1 to tight because i couldnt even start to fit a .18....did i have it completely at TDC???and any tricks to getting the valve cover back on would be great:worthy:

removing the upper motor mount does wonders :busted: (although you didn't specify what bike you have, but on my 426 it does).
Also (on my 426) you have to remove the upper plug to see the marks. If, for some reason, your marks are gone you can still get it to TDC by removing the spark plug and using a screwdriver as a feeler. Move the crank forth and back until you feel the piston being at the highest spot. That's the TDC. Now look again if you see the marks on the crank in the plug hole.

Do you have a manual? hope so, since the manual does a good job at explaining exactly what to do, where the marks are, etc.
