Rear sprocket swap
 

Going to upgrade to the 39T sprocket. How hard is it to do? I'm assuming I can figure it out once I get in there but any tips or tricks would be helpful to make it a smooth swap. Thanks

What buggy? You will need to either add to your chain or replace with a longer one.

Hammerhead 150.....I have new chain.....Just getting some info before I start anything.

You basically have to pull the rear axle. Not a difficult job, just remove parts. Bearings are not pressed on but have a snug fit onto axle.
