Dellorto PHF 30 carburetor fitment

A lot of information on this subject, there are already in the network to the relevant pages of V7 drivers. Problem with this is in addition to the size of the angle of the carburetor intake manifold in combination with the side covers and the transmission as well as the different ways of mounting the carburetor at carburetor flange. Various options have already been successfully implemented depending on the perspective of the viewer in terms of appearance and as much as possible maintaining of residual originality where it grds. 2 variants amounts:

• without side cover / open with appropriate air filters / trumpets
• with machined side cover and thus cutouts or shortenings

In the experiments, I started with the original piece and then with intake / manifold of follow models that had teiweise fitted as standard in the PHF Tonti Frame models and special designs such as the Ansaugstutzten plasti; in addition there are grds. the problem is that the 30-PHF carburetor connection rubbers required for connecting the carburetor to the port (in return for the clamping in the original 29/30 VHB / T carburetors).

About the V7 mailing list and friends I got a lot of information and help to leftover side covers for appropriate conversions (Many thanks to Uwe Ziebarth from Berlin, Ralf Brinkmann and of course my friend Greg Bender Guzzi from America). Aim at the reconstruction was the retention of the side cover and the original airbox. It quickly became clear that only the original piece to angle for airbox further provides back on Ansauggummis to leave the side cover.

About twisted and glued aluminum rings that make up for the connection diameter of the PHF carburetors / compound rubber, I came closer to the goal.

After I cut the ring and Ansaugsutzen for the left carburetor and the original Ansauggummis have also been reduced by a few millimeters, it now seems to fit. A little worry makes me the slightly tilted carburetor on the left side, the right fit better overall because of the displacement of the cylinder.

Whether we are working to see a release I can therefore currently Nocht not give, since I have not yet feriggestellt the complete renovation!!

Here successful conversions:

• Uwe's renovation: PHF 30 carburetors
• Greg Benders page: Dellorto PHF 30 carburetor fitment
• George Dockray Past Perfect: Moto Guzzi V700 Special

A really gelunger conversion while changing the cover page can be seen here as a suggestion:

Upon completion, the carburetor work very well. Due to the tilt angle just float level must be (here are 2 settings in the carburetors possible) be changed:

Almost done. Waiting on a few parts from Dellorto UK and then fire it up. Just because I know everyone will ask; no, the side covers will not go on for either side. Even V700 covers, which I have, will not make it. A minor problem. New manifolds being machined and welded up now to give a bigger turn in, 15° or so, and then refit the stock covers.

But, at the moment I want to be on the road now, not later. Just have to finish the carb setup and tuning, bolt up the dual 40 mm Brembo disks setup (Guzzi Power adaptors and Ducati 900CR calipers) and install the newly painted fenders I just got back from Steve Hill.

I threw on an old tank I have with cubes on it. As you can see there is plenty of clearance. But will there be clearance when I angle them in another 15 degrees or so to fit side covers? I think so as the vertical clearance seems to be enough with the handle down even if they were one on top of the other. If anything you may have to point your cubes in a direction other than what you are familiar with to get the handle out of the way of the cable.

Also, while the set of VHB's I built were well suited for my bike one of the reasons I went to PHF is the lack of VHB parts. Needles for example. Nothing controls your engine's response more than the needle. For VHB's you have two choices, V5 if you can find a good one, or V9 which is what I ran. On the PHF's I have 95 needle choices, K1 all the ways through K95. All readily available new.

The second reason is the far superior PHF accelerator pump. The VHB pump is a joke, a little dribble of gas into the venturi. The PHF will shoot a jet stream of gas across the room (I've done it). There is just no comparison.
