Stripped my hyper 1100 evo non sp forks to fit wilbers progressive springs, refilling with oil the workshop manual states 0.48l & 104 air gap. I filled 0.5 in each leg but have an air gap of 230mm. Do i go with the air gap measure? Wilbers website states 90mm air gap, so confused...
Not sure sir - ive never been able to fathom out the gap way of filling them....i tend to measure whats come out and then put that back in....
Got just under a litre out of both, never bottomed out so reakon putting the same back in & not worry.
you need a fork air gap measuring tool... https://www.ebay.co.uk/itm/Bike-It-...=283495581557f6b9d7566b634bf698a82a0fd4f18ce2
