Yes, you can change the speedo gear by removing the tailshaft, do a google and refresh your memory as you need to pull the shift lever and there's a spring and ball bearing and the pin that you knock out...but the tail shaft needs to pull past the top rod holding the forks in order to be removed.
The guy in Washington, from Ebay, takes the tire size and calculates the rear diff to decide what gear he needs. The online calculator I used basically did:
Code:
Tire Diameter * diff gears

Original Tire Size
That will give you the ratio the rear end should be, and by doing that I get a 3.34:1, pretty darn close to the 3.38 I'll be putting in there. I don't know if he will adjust up/down for the speedo drive gear.
Just sprayed some brake cleaner on it to try and clean the outside before I send it off to Washington. Need to find a box big enough also.
