Note the Harley parts on the right and my parts on the left.  I also had the large 
washer especially made. I found the large rotor washer from Harley could be 
out of round as much as .100 as it’s just a stamped-out part. I true mine in a lathe 
and then surface-grind it. My spacer is also made from chrom-moly instead of mild 
steel. The combined thickness of my pieces is .050 thicker than the Harley parts. 
The larger OD of my pieces help to prevent rotor wobble as well space the rotor 
away from the stator, thus helping to prevent the rotor from touching the stator wires 
and shorting it out.

I would like to point out that the Spyke rotor is more than twice as thick in the 
center than the stock Harley rotor. If it had been available way back when, I would 
not have had to spend the time diagnosing the problem and designing the rotor 
saver. I probably didn’t need the rotor saver with the Spyke rotor, but since it’s 
already in, we’ll leave it.

If you are going to get the rotor saver, remove the old Harley 
seal (#12026B), and following the same procedure I did with 
the transmission seal, install the new setup. Put Vaseline on
 the seal and the spacer. Put a little blue Loctite on the seal 
and then slide the parts on the main shaft.

Using the Jim’s motor seal installer, install the seal. 
DO NOT beat the seal in with a hammer!
