Wide frame seat with Imola tank

Hi all,
I got a "wide frame" repro Imola tank that I could in principle install on my 750 GT.
Apart from the footpegs, gearbox lever, rear brake pedal and kickstart lever... there is also the issue of finding a "wide frame" suitable seat looking like the narrow frame seat of the SS.
THe SS seat is ...

Re: Side stand for 750 GT sandcast

Btw, the very first sandcast 750 GT's (the pre-production batch of 100 bikes) did not even have the fittings welded on the left frame tube allowing to bolt a side stand:

For the few (happy) owners of such a pre-production model who would like to install a side stand, the only ...

Re: Side stand for 750 GT sandcast

From the manufacturer of the conversion kit, "this stand is not fitted in the original position on the front frame down tube. It is made to fit on the lower rear engine mount and the centre stand pivot bolt."

When looking at the underbody of my bike, I am wondering how that would ...

Re: Side stand for 750 GT sandcast

I have explored the conversion kit suggested by Ian.
The stance it provides seems to be more inclined and safer than what provides the stock side stand.

Here under the conversion kit fitted on a MHR:

In comparison, the bike on its stock stand looks ...

Re: Side stand for 750 GT sandcast

Funny, the side stands of more modern Ducs are often too short! making the bikes leaning too much and fall on the same side whenever the ground is not really flat or stable.
I am interested by a side stand because I am not very tall nor strong (I am now 72y. old) and I view the side stand as a ...

Re: Side stand for 750 GT sandcast

Thank you for the comments, Ian.
Although speculative, both suggestions look interesting.

That spacer (or a possibly larger one) may allow compensate the recess depth.
I note that it is apparently a true spacer, not a kind of shim to widen and adjust the bolt diameter within the hole as it is for ...

Re: Side stand for 750 GT sandcast

Thank you for your feedback.

The part of the "standard" side stand that bolts on the frame and on the crankcase is a forged blade of metal with a strong annular bracket welded on its rear to insert the special attachment bolt to the crankcase:

On a die cast bike, the metal blade ...

Side stand for 750 GT sandcast

I have been looking for a side stand for my 1971 GT.
Side stands for later 750 GTs are already difficult to source and very expensive, but I now understand and believe that for a sandcast model it is an unobtainium item :cry: .

The spare parts catalog of the 750 GT lists indeed two references for ...

Re: Better Oil Flow to the Sump, And filter ALL of the oil.

Ok thank you.
But then, in addition, you change all the system of discs/plates to be "dry" instead of "in oil" and I suppose also that the oil circuit is changed accordingly?

Re: Access to bevel support bolts

Thank you for your feedback, Steve.
This is what I thought would be my only option, the available space being however really tight even for a cut Allen wrench.
I will have to try that if the leak worsens.

I am surprised however that nobody seems to have ever raised this issue.
Strange that the ...

Access to bevel support bolts

I have a small oil leak at the base of one of the rear bevel support.
Apparently one of the Allen bolts (see red arrow) is not sufficiently tightened.

Unfortunately, access to this bolt is nearly impossible without removing the rear cylinder.
Any trick to tighten ...
