Took apart the kitsuma to change the stroke from 57.5 mm to 65 mm.
I used the same shimano bottom bracket tool to take the air spring body off the bottom eyelet that the double barrel uses. Then I put the 9.5mm shaft in my vice clamps, warmed up the eyelet body with a heat gun and removed the eyelet body, then the white plastic spacer.
This made the 57.5 mm shock into a 65 mm shock. If you want to make it a 60 mm stroke you will need a 2.5 mm spacer.
One interesting addition to the shock shaft was a 4 mm hex on the end of the shaft to be able to remove and reinstall the eyelet body onto the shaft without a 9.5 mm shaft clamp.
The shaft sealhead can be removed with a park pr2 cassette tool.
