:hmmm: Ok this I got off the Andrews web site.

BELT DRIVE SPROCKETS - INSTALLATION NOTES
Installing a transmission sprocket with more or less teeth than stock requires adjusting the rear axle forward (for more teeth on sprocket) or backwards (for less teeth on sprocket).
Rear axle position adjustment for each one tooth change on transmission sprocket = + / - .125 inches (3.2mm).
Rear axle position adjustment for each one tooth change in belt length = + / - .280 inches (7.1 mm).
If there is not enough axle adjustment at the rear frame, it may be necessary to use a belt with more or less teeth. There are at least 8 different drive belts available at this time. They have 126, 128, 130, 132, 133, 135, 136 or 139 teeth. The only sure way to tell which belt you have is to physically count the teeth. (Use a paint mark for reference).
1984-1993 EV80 overall final drive ratio (engine to rear wheel) is 3.37 to 1
Overall = ( 37 / 24 ) x (70 / 32 ) = 3.37
1994-2001 EV80 overall final drive ratio (engine to rear wheel) is 3.15 to 1
Has anyone thought of the 24 /37 primary and the 29 trans = 3.72-1? Would a speed trans be needed for open road riding?
As far a the recal on the speedo goes thats not a problem. Have a local stealer not far from here. This is just food for thought on my end. After the first of the yr going to take and rip my bike a part and make some mods. Got my money back on the (extend warranty)< that was almost a waste of money. Anyway :thanks: for all the input on this.
