has applied for an exemption from the prohibitions in Section 27156 of the

Ca]iforn%a Vehicle Code {VC) for the RevTech Programmable Digital Ignition
System, part no. 59—770, for all 1995 and older Harley—Davidson motorcycles

equipped with the 1338 cc engine, except those equipped with a factory fuel

injection system.

       Based on submitted emissions test data, the staff concludes that the
RevTech Programmable Digital Ignition System will not adversely affect exhaust

emissions from the Harley—Davidson motorcycles for which the exemption is

IV.      IGNITION SYSTEM DESCRIPTION
         The RevTech Programmable DiQita] Ignition System has been specifically

designed for installation on Harley—Davidson motorcycles equipped with the
1338 cc motor.    The ignition system operates in conjunction with the original

equipment manufacturer‘s (OEM) fuel delivery system along with the emission

control system a]readyvcertified with the stock engine.     The primary purpose of
                                          —1—


the ignition system is to enhance the motorcycle‘s overal} performance by

modifying the OEM ignition timing curve.         The RevTech Programmable Digital

Ignition System also has a built—in rev. limiter and a firing mode select.

       The RevTech Programmable Digital Ignition System has been designed to
allow the Harley—Davidson owners the ability to.configure the ignition system

to match their own requirements.        With four preprogrammed timing curves

installed, the Harley—Davidson owner can adjust the ignition system to

accommodate fuel grade, air temperature, and engine hardware.         Table 1 list the

conditions that work best with each pre—programmed ignition curve.


                                        Table 1.

Advance Curve                 Description

     Curve 1                       Stock engine, cool air temperature, or high
                                   octane fuel, this curve brings up the advance
                                   earliest and to the highest final vailue.

     Curve 2                       Slightly modified engine, warmer air
                  '                temperature, regular grade fuel, this curve
                                   brings up the advance a little slower than
                                   curve 1 to prevent detonation on near stock
                                   motors.

     Curve 3                       Performance engine, high compression, poor
                                   quality fuel, hot air temperature, this curve
                                   is good for built motors that tend to detonate,
                                   advance comes in slower than curve 2 and to a
                                   lower final value.

     Curve 4                       High performance engine, high compression, poor
                                   fuel quality, hot air temperatures, this curve
                                   should only be used if your motor still
                                   detonates using curve 3, advance is brought in
                                   still slower and to a lesser final than curve
                                   3.


       In addition to the adjustable timing feature of the ignition system, it

also includes a rev. unit select and a firing mode select.        The rev. unit

select allows the rider to either maintain the factory 6000 rpm rev. limit or

switch to a 6500, 7000, or 7500 rpm rev. limit.        The firing mode select allows

the rider to choose either a dual or a single spark mode.
                                           —2—


v.       DISCUSSION OF THE IGNITION _SYSTEM
         A 1989 Harley—Davidson with a 1338 cc engine was used for the evaluation

_of the RevTech Programmable Digital Ignition System.         Emissions testing was

conducted by Compliance and Research Services, Inc. of Linden, New Jersey for

Custom Chrome, and consisted of eleven Cold Start CVS—75 emissions tests on
various modified configurations.       The ARB did not pefform emissions tesfing to

confirm the test results submitted by the applicant.          A summary of the test

results is shown below with DFs applied:

                                 Standards          1.0                  12.0

         Results from the emissions testing conducted at Compliance and Research

Services, Inc. have demonstrated that the installation of the ignition systefi

does not cause tailpipe emissions to exceed the applicable emission standards.

fherefofie, based on the test results, the staff concludes that the installation

of Cugtom Chrome‘s RevTech Programmable Digital Ignition System, will not have

an adverse effect on those applicable motorcycles.

         Custom Chrome, Inc. has submitted all the required information and
fulfilled the requirements for an exemption.
