Installation & Idle Output

The included 1.75-inch pulley requires a slightly shorter drive belt for proper tension.

Output may be low or absent at idle, particularly at 400 - 600 RPM. Raising idle speed approximately 200 RPM may be necessary. Mechman recommends its 240-amp version for most customers seeking a better balance of peak and idle output. The 320-amp rating does not represent idle output.
