There are obviously a couple steps before you get to this point.
Like...
1) Take engine out of bike
2) Tear engine apart
... and so on
I got the parts in the mail today from BikeBandit.com so I decided to get at least this part of the project done. I have to go pick up my sprague clutch tomorrow so I can finish this thing up. The output shaft was already out of the case, so start to finish on getting the new gears on only took about 30 min and is very simple.
Here's some pictures, email me if you'd like the full size version of any of them.
