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?)

(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.
