On my "new" old UL the clutch rod rubs and springs off of the primary cover. I can't see any way to fix this problem, does anyone here have a solution? See attched photo, you can see the rod is bowed from contact with the cover.

Do you think that possibly over the years someone might have stepped on the clutch arm and bent it down? Should I try to bend it up a little bit to see if it will help? Come on guys give me some ideas......

it does look a little low, bending it up certainly would help.

do you have the correct rocker pedal? if i remember correctly there are a number of different ones.

That I don't know. I just got it. How would I be able to tell if it is the right one or not?

Hawkeye,

Try to find a copy of Bruce Palmer III " How to Restore your Harley-Davidson." Used copies from Amazon for less than $25. It illustrates and describes all sorts of year specific parts ...

Whether that's your problem or not I can't say, but you really should have a copy of this book for your library or shop. I think everybody on this list would agree that this book is the "BIBLE" even if there are some errors and omissions.

Your outer primary looks like an old repro one. It has a huge hump up fron for clearance for a compensater sprocket. V-twin started making really nice outer primary covers a couple of years ago that are right on. Even with the new outer primary cover, you still might have a clearance problem, but it will be a huge improvement. That is a really nice bike, I love those flatheads.

I'll look into the V-Twin outer primary that sounds like it might be the ticket, the rocker is a correct one from everything I can see on it and it will not "adjust" upwars any so the rod will clear.

Thanks, I just got it in last week and have just put the first 100 miles on it, had a few "tweaking" problems. Now if I can just get that Linkert M51 to idle better................

I've looked it up and I think I'll order a new primary tomorrow.

Sounds about normal to me. I never owned one that did not rub somewhere. Clutch arms are pretty tough so unless someone in the past torched and bent it down or it was involved in a wreck I'd say forget it.
New Knuckleheads? Thank, you, Jesus!!

I think the answer about repro parts is probably right. H-D made a whole range of basically similar parts that look the same but are slightly different in detail, wheras the AM industry tends to make parts which are about right for more or less anything, but slightly wrong for any given application.
Shoot, a man could have a good weekend in Dallas with all that stuff...
