Hello- I did a top end rebuid on my 06 wr450 and i'm putting all together to find that the cam chain doesn't fit over the cam gears. The tensioner is off and the chain seems to be around the crank gear correctly and the part# is correct for the chain, also everything is stock. Isn't the cam chain supposed to be loose enough to get it over the gears until you put the tensioner on? And if so do you have any idea what i did wrong?! I'm at my wits end here and any advise is MUCH appreciated!
