Sorry to hijack the thread here but what do most poeple do to the front shocks?
I don't see a "most" answer doing service to your very good question.
It's really a matter of stages :
1 Do nothing.
2 Make sure front end is straight and both sides squared up and parallel.
2 Set sag and adjust rebound adjustment as best possible.
3 Change fork oil to higher grade, not thicker, better quality.
4 Respring to suit your particulars, 919s being notoriously softly sprung.
5 Modify stock internal compression and rebound valving.
6 Fit aftermarket valves, be they Ohlins, Racetech or Traxxion
7 Fit aftermarket cartridges by Traxxion, one leg has external Compression adjustment, the other has external Rebound adjustment.
8 Graft on an upside down fork off another bike, likely an RC51. (some have put on 600 Honda SS front ends, but there seems to be way more interest in RC51 fronts on 919s than anything else on the basis of what I have seen so far on WT)
My 919 is Stage 6. (Ractechs)
