An engines idle speed is a programmed function. We cannot directly adjust the engine idle speed on a modern vehicle. The power control module or PCM provides all adjustments to the idle speed. Though no external engine idle speed adjustments are possible, many things can and do cause problems.
It is recommended to use an aftermarket idle control when using a 28mm carb. Idle should be set at approximately. 4000 - 4200 RPM with clutch engagement at approximately 4500 - 5200 RPM. Gearing: For fastest E.T., use a 68 tooth 415 rear sprocket and a 9 tooth front sprocket for a gear ratio of 7.55 or a 90 tooth.
