Well
using 2008 ninja 250 front end in a 1993 ninja 250
Using race tech emulators and springs.
RT recommend 10mm preload.
It turns out my spacer then must be 12 cm long.
If I buy SSR preload adjusters, they have preload from 5-20 mm
(it is not that hard to make new spacers but also checking making sure my head calculations are correct)
The the SSR adjuster mean my newER spacer should be 5mm shorter to start at a preload of 10mm? A spacer of 11.5 cm length?
my preload on the 2008 suspension (which I bought used as parts) was pretty much the cap width ( 15 mm)
FYI::: Rider weight (160 lbs):: bike weight ( I think 320 lbs dry):: spring .75 K:: emulator 3 turns and blue 40 lbs spring::novice racetrack rider:
reload 10 mm:: (oil height) 140 mm
dont have the SSR adjusters yet so was gonna make 2 sets of spacers.
Set #1 (11.5 cm long)
Set #2 (12 cm long )
