How many teeth??
I have a1998 Dyna Low Rider and I'm considering changing my rear drive pulley to a 65 tooth down from the stock 70. My stock belt has 133 teeth, what size belt would I need for the new pulley?
Thanks folks

Here is some info from the Andrews website. They make replacement pulleys for the primary side (forward side) of the final drive. Perhaps from this info, you can interpolate, approximate, and/or guess what 5 teeth added to the rear sprocket might do. Lots depends on how much/little room you have on the existing asle adjustment.
This doesn't answer your question, but it's something to think about.
Good luck.
PS. I'm also wondering why you want to gear your bike up, rather than down???

In order to have any adjustment left on your rear axle, I would think you will need a belt 2 teeth shorter. For each tooth change on a rear you gain/lose approx 1/8" of adjustment on the axle.
Since you have to replace the belt, I would change the front sprocket instead. each tooth on the front equals roughly 2 teeth on the rear when changing. You can change 2 teeth on a front without changing the belt. Either way you are opening the inner primary.

I might be interested in your 70 Tooth/Gog rear pulley, mine's a 68 tooth so that would give me a little better bottom end.
PM me if your interested in unloading the one your changing out.

Less than 10% change, or roughly equivalent to a 2 tooth change on front, not that big of a difference

So you want more top end? or lower revs at cruising speed? Most go the opposite way (more teeth on rear pulley, less on front) for more acceleration.
