I bought a Lotus L3 1 months ago, but the idle speed was too high, about 1200. Could you please reduce the rider's idle speed? How to adjust it?

Idle speed 1200 is really high. It may be an idle motor or a throttle. It is suggested to check whether the idle motor and throttle valve work normally with the automobile computer detector, and then make a judgment according to the detected problems. If it is an electronic throttle, it must be adjusted with a computer tester. Never be blind, so as not to damage the parts.
