@markanddona,
I must thank you for bringing this up.
I've been a fool to suffer and doubt the bike for almost 30h with the incorrect springs.
I replaced the Stark "Soft" springs (4.6 / 54Nm although there are no markings on them) with the S-Tech 4.8Nm for the forks and 56Nm for the shock and the transformation was immediate. This was done on hope and a prayer and every aspect of the bike is now improved. Even the power delivery is sharper since the bike isn't sitting so low and will now hop almost like a 2T.
Recommended sag setting (40 / 110mm) came right away while the 54 spring required a lot of preload.
I only did one ride without any other adjustments and every lap was a new record by a large margin and without pushing for it.
I now believe that with optimally tuned suspension and (hopefully) future improvements with traction control the potential of the Varg is infinite.
