    Default 58 XL Sportster points gap? (Magneto)

    LACK of information on the web for 57-58 Sportsters, need the recommended points gap.

    I have a 59-75 Clymer service manual, says 0.015" for magnetos, 0.018 for battery ignitions- are settings for 1958 models different?

    Are there any OTHER differences on the 58 I need to be aware of?

    Thanks much for any help!

    There is no spec given because no magneto was ever originally fitted to a '57 or '58. Use the later mag spec as all mag settings are the same for all years. Clymer manuals make good bird cage liners and fire starters.

    Thanks Robbie, this old buzzard has been bastardized over the years I'm afraid, will go with 0.018

    The 1958 XLC and XLCH models had a magneto ignition.

    True, but those were both limited edition competition models in '58 (no lights stock but with a light "kit" for the CH for enduros), and the '59 XLCH was the first regular production road model with a magneto, however no XL ever did come with one...

    They were in the brochure and standard parts catalog, not "competition models." A buddy of mine had a friend that walked right into the local dealership and bought one off the floor. Fitted lights to it and rode it all over the place. They were only limited production in that not many people bought them due to the lack of lights. However, to reinforce my response: Harley did produce two regular production Sportster models fitted with magnetos in 1958 (XLC and XLCH).

    Sportster Jerry is correct regarding the 58CH. Factory records indicate that 239 were produced. The story (according to Margie Siegal) goes that several California dealers committed to a short run of off road XL's and Walter Davidson agreed as long as they took them all. I am guessing that about 200 came to the Golden state and the rest were send to the remaining 48 states. I heard that 4 went to Illinois. I know that one was purchased by a HD employee. I am attaching a photo from the HD archives. I have personally seen in photos about 25 or so and touched 5.HD archives 58CH 1.jpg. I have photos of VIN's of several. Beware there are a lot of fakes out there.
    Years ago Gene Bowmar (of Bowmar magneto fame ) told me to set the points at .014" and plug gap at .020". I have been doing that for 40+ years and its the right combination.
    Hope this helps.
