Thanks Steve, unfortunately the Ducati catalogue of the day doesn't itemise individual parts for them as they were (apparently) only supplied as a complete unit. You had a choice of three types, Euro delivery GT (black cover), USA delivery GT (bare polished alloy cover) and Sport (nil cover). The ...

I know it's a long shot, but I'm searching for a pair of spring adjustment sleeves to suit the early 3-ball type adjustment Marzocchi rear shocks as found on 72 - early 73 GT's. Anyone know a likely source please PM me. Cheers, David.

Hi, looking for a set of 4 tapered-head bolts to fit a stainless 750GT front guard on to the stays. I think they are around 5 or 6 mm thread.

Does anyone have a shortcut for me to obtain NOS originals? (no i'm not hopeful either...) or failing that, the best place to source a set of similar but non ...

Wow. I wonder if he used a mask?? Lets hope he doesn't take up watch repairs...

What size carbs, main and pilot jets are you using??

I agree, sounds like fuel starvation.

Greetings,

I am currently trying to source an 'Inox' stainless front guard for my 73 GT. I'm fairly sure the 72 and 73 had the same type guard (correct me if i'm wrong). Any condition will be considered. Please PM me if you know of a source.

David.

Try turning pilot screw a bit (half to 1) turn further out. You may find that it is running too lean on the idle circuit. I had the same drama with my 32 mm Dellortos, 1.5 turns out is not far enough.

Dont muck with the jet sizes (providing they are in the ballpark), just ensure that there are no blockages.

You mentioned a backfire. Was this comming from the front cyl?? If so it could be an indication that it is too lean (ie not getting fuel) and this assertion is supported by the fact that it ...

Regarding the hot/cool cylinder, you will probably find that the cool (horizontal?) cylinder is not sparking/firing correctly. When you lift the individual carb slide, that particular cylinder should increase in revs. I had exactly the same dramas with my 750GT caused by a fouled plug.

To confirm ...

Just a footnote for those that are interested on what turned out to be the cause of the plug fouling. I have posted this to assist other owners, as there have been several 'plug fouling' threads on BH of late.

It turns out that the vertical cylinder which was giving me the most grief was running ...

The 72 is certainly a teriffic looking bike (as are the others!). The paint scheme on the 72 tank and seat looks great.

Was the 72 tank different to the later Sports?? It just looks a bit larger, flared slightly wider at the bottom, similar to a later GT tank shape. I realise that the 72 had a ...

OK, I've been doing a bit more tinkering and have some interseting developments.

Firstly, I have double (triple) checked the spark situation (again) and have found that the vertical cylinder spark aint that bad after all. The horizontal (the one I tend to check the most) is still poor. Guess which ...

Yeah, I thought the question about the timing would raise some eyebrows, I'm aware that it wont alter spark quality. I just didn't want to start a new thread on ignition timing when there one may already exist. I've checked and can't find one.

Anyway, the bike kicks like a pregnant dog and is ...

Slowly getting there. Reviewed the ground point near the coil and have seen a slight improvement with the spark, however the problem is still there.

I have run all the voltage tests between the distributer and coils, all seems to be functioning correctly.

Is anyone able to point me in the ...
