If you can aford it,the 989 stroker is the best kit of the bunch.Check out the increase in torque over the other kits plus the hp isnt bad either.I installed a 904 kit in my Speedmaster and the difference was amazing but i still would like more torque.I run a 19 tooth sproket and lost a little stoplight acceleration but made it a pleasure to ride long distance and made it smoother with the throttle response.Would never think about going back to the 17 tooth but would like a little more torque and the 989 would be the ticket.
