That's an interesting description. I would have thought a BMW is refined. How is an SS more refined than a Darmah? Rawer, yes - refined, no.

Taking the bait...

Kev

ok kev-bait taken
macquarie dictionary--refined
1-imbued with or showing nice feeling,taste
2-free from coarseness,vulgarity
3-free from impurities
4-subtle
5-minutely precise,exact

end of story really-sounds like the super sport to me--not the drama

Steve,

Well done! Where did an SS owner find someone to read the dictionary for them so quickly?

Kev

methinks this thread has drifted off topic-to be continued in another place

yep. good thinking.

Hi there,

my '80 Darmah is equipped with 40 mm carbs and starts and idles very good - can't be better ! High end performance with Contis is great > 200 km/h ! Torque at low revs is fine with Lafranconis and gets worth with Contis, but is still o.k.. It runs well with both set ups, the engine always feels good and always delivers performance. Even in town it is good to drive.

May be you just need to find the perfect set up of the 40mm Del'Lortos - then you would not think about changing to the 32 mm carbs.

In 1979 the main german motorcycle newspaper "Motorrad" claimed the 40mm carbs would be better than the 32mm carbs in any manner !

See/listen my Darmah after 13 years of rest - 40 mm carbs fitted:

Have fun

Late SD's had the polished rods, for instance the '83 blue-paint-with-silver-stripes SD that I rebuilt a few years ago. It came that way too - a friend bought it new and I cut the lead seal between the case halves. Late SD's had 78-on style SS engines with electric start and smaller carbs. The deeper SD-specific cost cutting stuff was changed to SS-spec over the Darmah's production run. This must've been done to simplify manufacture of different models using the same basic powerplant.

Otherwise, I agree - for instance the SS frame works better than the Darmah's frame. The same is true for a 750 GT. SS or 750 GT frame designs with lugged engine mounts steer in a more refined way than the stamped frames that started with the 860GT.

My 80 SD has 40 mm PHM carbs with "flush pins" (how is this called in English ? - in German we call it "Tupfer").

How long should it usually take to press this "Tupfer" until the fuel spills over ? Right now it works instantly - before adjusting the float it last 4-5 seconds.

Cheers

Ticklers,
someone, i think on bevelheads list told me to count to 12

I used to do it that way , now'a days I push up and down until they start to squirt fuel from the top overflow as soon as they do that two full throttle squirts and away you go

Thank you Garry - I wonder, if 12 sec. is not too long

Best regards

Joe

ups.....Australia is awake

I did push the tickers a few times too back then, but it should not make a difference, since you just open the float valve. It might even enhance the wear on the floats plastic surface

I will get a workshop manual especially for Dell' Ortos (in German) soon. Hopefully I will find every information I can think of.....

Cheers

Joe

From the Workshop manual , and its pretty much what I do

Page 49.

Starting

To start from cold, the (d) flooding-plunger should
be pressed five or six times, lightly opening the throttle

I extremely cold conditions, it is advisable to open the
throttle once or twice, so that the accelerator pump can
squirt extra fuel into the inlet, making starting easier.

The float position can easily be adjusted to either slow or accelerate the flooding process. All that is required is to bend the metal tab on the float. Moving it down slightly opens the float bowl inlet valve more quickly, thus reducing the time required for the bowl to overflow through the plunger. Bending it up reverses the proceess.

I just did this last weekend since my bike's front carb refused to overflow, causing the bike to only run on one cylinder at start-up.

The Dellorto manual in English is widely available on the web.

Not 12 seconds, count to 12 not sure whether it is slower to count in german
