OK, in middle of doing the valves on my 2008 Grizzly. This is my first time doing them myself.
First question – in regards to getting the engine to TDC, I turned the crankshaft counterclockwise until the intake valves open/closed. I then lined up the "I" to the mark with the stationary mark. I am having a hard time seeing that "I" mark on the magneto rotor. There is an "H" and then the "I" beside it. I don’t want to screw this up. Is there another way to double check that I am at TDC on the compression stroke? Damn near need to have a bionic eyes (or be young) to see that "I" mark that has oil on it.

2. To adjust the valves themselves seem straight forward. But, on mine, both for intake and exhaust, the valve rockers can be moved up maybe half an inch by hand. Is this normal or do I not have the TDC right?

And if this is normal, do I hold the rockers from moving to set the valves properly?

I’m determined to get this done properly.

Thanks for any help.
