Le Mans III carburetors PHF36B, from what model they are?

[jacksonracingcomau]

Anyone ?

Thanks Martin,- now I don`t feel so alone and abandoned any more !   It`s like finally -after a long , lonely and exhausting walk through an endless desert, to meet a person who gives you water to drink and tells you that he recognizes what you`re saying!
 :bow ;D :BEER:
I`ve been searching the web without finding any documentation for the existence of the early PHF36 D`s myself.

Right-

I mainly posted the pic of the newer type, anodized, 21mm float nut D`s to show that they also are rubber mounted like the B type.

Thing is I`ve been monitoring the German eBay for years, and have seen the early type D`s auctioned several times in connection with roundhead LeMans` being chopped up for sale.

But I am not yet ready to fully give up the idea that at least some of the round fin LM`s came with the PHF36 D `s,- which also Martins Dellorto catalogue pic could indicate. Thank you for posting that !
   So,- as to the difference(s) of the early (14mm float nut) non shrouded B and D type, we still don`t have an answer!

Your reply here all we ever need to know, if they appear on German ebay as OE LM , chances are they were German market, only thing that jumps out at me is needle clips, just perhaps Germans were more prone to losing the B type clip, so they got the really tiny little clip (#31 in pic) as punishment. If they got funny jetting, it was likely pre shrouds IMHO.
There use to a jerry on here with a few old Guzzis, Jan was his name but I think he offended someone, was going to meet him in Belgium but he didn't like riding in rain so never made it, I'll look for his email and pm it to you, he may know the answer.



Pete , did you mean cattledog ? My Kelpie cross is offended, my Dell Orto catalogue emotionless

Ah yes, the tiny little E clips. That's what my LM 3s have and I never had an issue years ago but as I get older they seem to have it in for me.  :BEER:

There are a couple of simple techniques that can still get them to do what they are told though.  ;-T

I was thinking float weights Martin. There are a couple of different ones of those and even though I have no idea why the identifier on the body would change the jetting would be altered.

I've got to say I think the needle clip is a bit of a stretch.  :D I'll just throw some ideas out there. The only real difference between a PHF and a PHM is they basically bored out the carb body to such and extent that the standard choke plunger system wouldn't fit so they had to make a tiny little choke box to bolt onto the side. Makes jack all difference to how you deal with them but they gave them a different name.

If you look at the inlet side of a PHF-ish carb here are 3 inlet holes that go to certain fuel circuits. The ones I have here usually have one of these (I can't be bothered to pull carbs off bikes) that have never been drilled/opened/bored. I'm wondering if it a variation in how the circuits are plumbed.

I don't know and I've gotten to the point that I don't care. I'm genuinely glad that Kidneb is a happy man and I'm also glad I participated as I've learned a few things in this thread and dusty memories have been dragged out of archives. If you do ever dig up the Tyrannosaurus D then let me know. I'll happily poke at the fossil.  :BEER:

To me the D is the (D)amn big nut on the float bowl. A is for anchored, B is for bouncy and D is for the big nut thing. 

Cheers

Gentlemen (using the term loosely),

Am in possession of an 850T, snatched from the jaws of death, which I have been piecing back together, bit by bit, over the past three years. It is not stock. Not even remotely close. But neither is it particularly radical.

Am fitting a set of Dellorto PHF 36 carbs to the beast and have been seeking a starting point for the jetting it will use.

Have just waded through this old thread, again, and am struck by the following:

(1) What a wealth of information Wild Goose Chase is. A veritable gold mine, I swear.
(2) What a bunch of laughable tossers many of the contributors are. Said in a kindly and compassionate way. Present company included.
(3) What a nightmare it can be trying to glean consistent data from sources that are Italian, German and with both European and American versions.

Nevertheless, I appreciate all who weigh-in and drink to your health, longevity and cantankerousness.

I have purchased a 1983 Le Mans III, but this 'bike has black valve covers, exhausts and wheels, with an engine number beginning with: VF0177** which does not fit with the published information for a LM3, so I am rather confused now. Might anyone be able to cast any light upon this?
This 'bike also has Dellorto PHF 36 D S & D carbs. Are these the "lean burn" type (it came from California) and how should they be jetted?
Thanks.

[guzzisteve]

Yes, lean burn. Many set-ups depending what bike and intake & exhaust you have. Got a pic?
