Re: Hi all!

Hi Miguel,

Welcome!

Craig here, also from the Laverda Forum. This site isn't nearly as active as that one; but you never know ... :)

Btw, I have a SSD (plus a Vento and a SCR).

Saludos!

Re: Dell'Orto AS v BS

Makes sense, Colin. There was a similar story with Dramahs. They went from PHF32 'A' to PHF32 'C' (i.e a designation that had nothing to do with the type of mounting :?), and from a 60 idle in the former to a 62 idle in the latter. But what wasn't shown was there was an internal restrictor fitted as...

Re: Dell'Orto AS v BS

You know, Colin, this question comes up every now and then and I'm still not clear ... According to Dell'Orto themselves, that 'A' / 'B' / etc designation on both the PHF and PHM carb ranges describes the type of connection to the engine . But there is inconsistency between PHFs and PHMs. PHF: 'A' i...

Re: To Split a case or not to split a case…?

<snip> Is there some way of making this decision. Only your personal 'risk profile' :) The problem is that it's very difficult to gauge the state of the big ends with the crank still in the cases ... And some will tell you, even with the crank still pressed together. So: 1. Are you prepared to pres...

Re: darmah - leaky 36mm dell'orto carb (and headlight reflector repair?)

i believe the carbs on this bike were swapped out for the original 32mm carbs. would a 250 work with the complete float valve assembly, even if something different is in there now? and/or are you still confident that a 250 is the right size? 36mm PHFs, as fitted to standard to Pantahs, came with 25...

Re: darmah - leaky 36mm dell'orto carb (and headlight reflector repair?)

P.s Another precaution. Take the dip stick out and smell the oil in the sump (!). If there's any wiff of petrol, it means some got past the piston rings and is now in your engine oil.

Not really desirable 'cos it will denature the oil. Best to do an oil change.

Re: darmah - leaky 36mm dell'orto carb (and headlight reflector repair?)

It's the float valve. https://www.dellorto.co.uk/wp-content/uploads/2015/05/103751-600x600.jpg When you open the petrol tap, the hydraulic head of the petrol in the tank is pushing the valve off its seat allowing fuel to flow from the tank and fill up the float bowl. And then it pees out of the air ...

Re: Pantah 500 Carbies

H Alistair, As Ducadini has said, as well as getting the float height right, it's important that the rubbers at the bottom of the choke pistons are sealing correctly, when the cables are hooked up. Easiest way: simply fit new pistons. You can muck about with trying to flip the rubber seals over; but...

Re: Pantah 500 Carbies

Hi Alistair, Personally, I would persist with the carbs you have. After all, Dell 36 PHFs have worked satisfactorily on Pantahs, and continue to do so, over many millions of miles now. I suspect you're not getting the set up correct. Rich running is, for example, a classic consequence of getting the...

Head bearings, Marzocchi forks

Hi all Am (finally ..) getting round to replacing the head bearings on my SSD and I see in the parts book there should be this washer, located underneath the top fork clamp and on top of the bearing adjuster ring ... Piece 16.jpg Well ... a) I ain't got one. b) I'm mystified as to its purpose. Anyon...

Yup, as you can see from the attached both Lafranconis and Silentiums have generous indents for the axle nuts.

Re: 78 Darmah Silentium vs Conti mufflers

I have to agree with you. Contis are simply too loud for street use. Had them on my MHR and quickly grew to hate them. To the best of my knowledge, they were never homologated in Italy. And they were never fitted as standard to Darmahs, being sold - strictly speaking - as part of the 'Tuning Kit' th...

Welcome Trent, In order to say who can help you with it, you need to tell us what country you're in .... ;). There never was a shop manual specific to the 750SS. (I guess you know how rare they are?

Re: best sparkplugs?

<snip> ... for example, you say "stick with what the manufacturer specifies: 0.5mm in NGK's case." but, ngk says 0.7mm for the b6/7hs My source for the 0.5 was NGK at this address: http://www.ngkpartfinder.co.uk/mc_search.php?type=SPARK%2520PLUGS&manufact=DUCATI&model=900%2520Darm...
