SV1000N K3 fork question
One for the guru's. No disrespect to the helpful folk who will re-post lots of advice but ideally I need some info from someone whose done it for real.
I've got a K3 SV1000 with a standard front-end. I've been doing a lot of googling and have read the manual and all the usual stuff and I now have so much contradictory information that I'm probably now worse off than before.
Current plan:-
Take forks off (having first loosened the top caps and made note of existing pre-load, compression and rebound settings.)
Caps off, remove the cup shaped C washer. Loosen the adjuster rod lock nut, then unscrew the fork cap/preload assembly. Remove the plastic spacer and the fork spring, noting which way up the spring was.
Tip out crud, pump stuff and leave upside down for a bit.
Refill with new oil (Question 1)
Pump until no air
Check oil level (Question 2)
Put back together, put back on bike, marvel in the transformation of my slightly wayward handling.
Question 1:- Oil weight
I'm about 14 stone (200 lbs)
Standard springs
It seems according to my research that something between 2.5 and 15wt mostly 5w and 10w come out as the most popular although each manufacturer's weighting varies so one manufacturers 2.5 may be thicker than someone else's 10 apparently. What would be a recommended oil weight and manufacturer?
Question 2:- Air gap
Apparently the N has a smaller gap than the S and the K3 may well be different again. The volumes also vary but I assume that given my initial intent to go with pumping and tipping rather than a full strip I can't guarantee it's going to start completely 100% empty so best going for gap rather than volume. I assume this is measured with spring out and shock compressed.
Main PDF suggests 162mm gap, with 494ml oil
K3 1000N supplement does not cover gap but says 508ml oil
Google seems to go for 135mm airgap for a K3-N
Now I doubt the 12ml difference will account for almost 30mm of height difference so not quite sure what to do here. I can measure what's there before I drain but most seem to be random and different between legs.
So in summary
Q1. Which weight of which manufacturer oil
Q2. What air gap
Q3. Have I missed anything crucial?
