Yamaha YFZ450R Top End Rebuild Part 3: Assembly | Partzilla.com

Get the supplies for this part of our YFZ450 top end rebuild here: bit.ly/YFZ450R-top-end-rebuild...
We’re wrapping up our three-part series showing you how to rebuild the top end on a Yamaha YFZ450R. In this video, we’re done with the top end and it’s time to put our ATV back together again.
We’ll pick up where we left off in part two: the spark plug. We’ll show you how to install the airbox on your YFZ450, and then we’ll get the exhaust back on. Our ATV won’t run without gas, so the next step will be to get the fuel tank bolted on and connected. Then, we’ll crank it up to make sure it’s working and get the plastics back on.
