Also, dont buy a supercheap chain. Read what happened to SSSticks supercheap timing stuff (granted it was the tensioner, but meh). For this job its worth it to go genuine. You wont have to do it again for a long time - if ever - so just pay a little extra. The chain is $105.12, or $81.81 if you can get trade
Pull the motor out if you have access to the right equipment
