ukzx10r have you actually explained all these problems to a dedicated and professional suspension shop?
Did you show them your rear tyre pics? (those ones that had the terrible wear pattern).
What did they say / try to sell you?
Ive spoken to specialists at track days who have said the gen4 shock is junk.
Also one gave me advice of letting off the damping which destroyed the tyre and made my bike feel worse.
Everyone advises a decent rear shock which is obvious but i havnt had any spare cash to buy one as they are alot of money.
Im thinking taking the plunge soon though as i cant keep riding hard on a bike that wants to ping me off alot.
My luck will run out one day
Currently trying to find someone who can help.
Was hoping i could get enough onfo off the net to get it close on my own for time being
