I am not a suspension expert nor a sales person, but here's what I experienced and what I went through:
Tested and tracked pressures for 4 rounds - No success so......I got drastic:
#1 - Suspension - Stock shock was to light and set wrong - Had it set by someone who knew what they were doing
#2 - Was suggested I buy a new shock - Bought new Elka, had it setup still had problems with tearing
#3 - Wrist/Throttle - Charging hard out of the corner, needed to carry more corner speed (easier said than done at the time)
#4 - Changed tire compound (went to a hard compound then soft) - No success
#5 - Change tire brands - all bike setup remained, problem was almost gone ( I believe some tires work better with some riding styles - tire is not better or worse, just better for you and how you ride at that time)
#6 - Dave S. did some more fine tuning, took out some rebound dampening (so the rear would come up faster), next sessions, completely gone, even wear and 1s faster per lap. Finally....
First things to try/change - Listed from cheap ones to costly:
#1 - Longer in warmers, good heat saturation
#2 - Pressure's - I use to keep a record of pressures(cold vs hot), tire wear and ambient temperature (find the right combo) + dates and wear vs feel (anal yes but I needed to solve this costly problem)
#3 - Try adjusting the shock - speak to one of the clubs suspension "Guru's"
#4 - Try a different tire brand or compound(if your tearing up tires, the cost is the same, regardless of brand or compound - buy take off's)
#5 - Go back to #2 - still fails go to #6.
#6 - Buy new shock, set it up go back to #2.
By round 5 I had finally solved my issue, only cost me 4 sets of tires and 1 new shock....I am not claiming changing tire brands is the answer but this problem can be attributed to more than one variable and the fact that changing brands was the last thing I did, could just be coincidence. I hope my experience helps give you some insight and saves you some $$$.
