This unit is a little larger than the original and the aftermarket unit this one is replacing. The electrical post is located in a different place, which makes alignment with the sprocket a little tricky. I found the spines on the starter motor a little rough so the sprocket would not slip on easily, making complete insertion and bolt-up impossible. I took the sprocket out and tapped it onto the splined shaft gently, slid it off rotated 1 spline at a time repeating the process until the fit-up of sprocket to shaft was smooth, this allowed a good fit and bolt-up. This starter spins the engine much faster than the original. I'm impressed, and would highly recommend this unit.
Starter fits very well, Splined shaft slid right in to the sprocket. Starter cable provided, is long enough to reach starter solenoid, Fit and finish is good. Product turns the engine over faster and easier than the original ever did. Installed on a GL 1100
