When I line up the TDC and then installthe CAM shafts, the TDC sprocket rotates a little. Is this normal? After I rotate the crank shaft a full rotation, my TDC is off. Is this not supposed to be on TDC 1-4 if you line it up again>

Any help would be appreciated. I've tried this a few times now and it turns out the same each time? In order to get the cam caps on, it takes a little pressure (normal?).

Possibly cam chain tensioner not tightened down enough? Maybe this will hold the chain from turning? The manual says to install tensioner temporarily and cap bolt lightly.

Thanks!
