It shouldn't screw up your speedo.  The first generation b6/12 speedo drives off the front wheel.   The newer ones drive electronically (?) from somewhere else.  (Is that vaque enough?)

Not "shouldn't" - it won't! The only thing that will change your speedo on a 1G is changing the size of the front tire.

The 2G speedo gets its signal from a sensor on the countershaft sprocket. Gearing changes will effect the speedo on a 2G.

I meant to say 'shouldn't screw up the speedo anymore than it is already', Paul, since most are off quite a bit.

If you change out the front sprocket with an aftermarket on the 2G bandit will you still get a speedo reading or do you have to have  the stock front sprocket for the sensor to work.  I stuck with the same tooth count up front but just got lighter front sprocket!

You still get a reading since the sensor is on the shaft, not the sprocket. It'll just be a different reading than stock if you alter the tooth count (gearing) at either end.
