Those bosses for forward controls were absent on 1977 FX models. Pretty much all other years had them.

Also absent for 78 FXE models. One can only "assunme" it was done to prevent a person from buying a base model FXE and up grading to something like the FXS model but on the cheap.

This thread is getting a life of its own, but entertaining. . As for the frame bosses mentioned whatever the MoCo did or not is confusing. I get the use what is on hand assembly in some instances. I’m always learning something. Going back to 1980 1200cc shovels - I know they made ‘em. I came across this documented FLHP 1200. Now I gotta find an FX bike with a 74”.

I found MORE confusion here in a Harley print ad. It states the 1981 bikes can run on regular leaded fuel, WHAT? The 80” engine was supposed to be set up for unleaded so why that? I never ran regular and by the leaded gas was scarcer ever so since 1975. I suppose unlike an auto with cat-converter maybe no real harm to the bike from a little lead. My 1979 74” frame label, leaded premium only, it cost me to set up my heads for unleaded swill. The Sunoco high test unleaded was my preferred back then. Better yet-Who remembers the days of Sunoco 260 ?!? High octane leaded nectar.

A little fuzzy but they state leaded regular in the 1981 bikes?

I gotta move it, I have a local run to attend. 19th annual Mel’s run. Raises a money for the childrens medical center. I’m not much for these things but since it is local event kicking off in town and ending in town, I know a few people it be fun to see. Besides that kids med center was great to my daughter when she was a tot.

Agreed, we all knew the 80” intro half way through 1978 in the FLH were designed to use unleaded…but high test. I found the text of this print ad referencing leaded regular as being odd - unknown to me. That’s why I posted it. The 1200’s always took leaded premium. The frame label on my ‘79 FXEF was clear.

it was the exhaust valve seats that suffered with unleaded, they would overheat & get eaten away without the lead coating that protected them,
it is why to run unleaded you should have the exhaust valve seats replaced with harder ones,
there is NO NEED whatsoever to have the inlet seats replaced as the intake of cold fuel protects them,
when ya engineering shop tells you to have both replaced, it is only to double their profit ........UNLESS the inlet seats have sunk due to natural wear over many years &high mileage.....
