Gen 3 cold start issues

I’ve noticed many people stating the gen 3 struggling to start with the widespread cold. In the past, my 22 would not start below 32 Fahrenheit. I adjusted my valves and found one of the exhaust valves too tight (touching shim). Now it fires up instantly. Are all these bikes valves out of spec? Anyone have a similar experience? At one point the blame was on the KACR but many bikes are out of spec from factory.
