Going to replace the original fork springs on my ‘92 3rd gen with .9 n/mm YSS ones as recommended by various calculators on the web.
I refurbished the forks last year with all new seals and oil etc so looking to simply to replace the springs without taking the forks off the bike,
current oil level/air gap is 178mm as per the service manual but I’ve noticed that YSS list a level/air gap as 160mm.
Original spring length according to the manual is 427.1mm and the YSS ones are 438mm.
So, should I install and leave level/gap as is (extra spring length will displace oil to lessen the gap?) or add oil?
