Has anyone installed a chain drive themselves? Whats the time frame look like?

 

in the middle of doing one right now on a 99 dyna. had it all apart in less then an hour. a lot of people have a hard time getting the main shaft nut off on the front sprocket. the nut retainer was the only thing stopping the one on my friend bike from walking itself off, it was literally taken off by hand. just waiting to get master link pressed in on the chain and we will be putting it back together
