I called a couple of Kawi dealers and asked what the stock fork spring rate is (it isn't listed in the owner's manual or the shop manual) - one said it was .40 and the other said .43. Springs rated at .40 and .42 are listed as optional in the owner's manual, so I'd guess that the stock springs are .41, since that's the only gap in optional spring selection. But it's only a guess :confused: .
I'll try the rebound at about about 8 or 9 clicks - thanks for the tip.
