Re: 900 GTS Tachometer

Oh, forgot to mention. If you do do into the front bevel cover, make very sure that the drive peg and little locating sleeve are securely in place and can't escape. You`ll see what I mean if you go in there. If the drive peg escapes while running it could be pretty catastrophic to your cam timing......

Re: 900 GTS Tachometer

I would start with the easy things first. The end of your cable goes to the front bevel drive cover. Carefully unscrew the cable from here and have a look at the cable drive. From memory the cable has a square end and fits into the tacho drive. Make sure the cable is actually engaging in the drive. ...

Thanks Ducadini and Vince. Was toying with the idea for next tyre change but remember reading an article somewhere that warned against it. Might just stick with what was meant to be......................

wider rear tyre

Has anyone experimented with wider rear tyres on their bevels?. I have read somewhere it can play havoc with steering geometry.

Re: 75 860GT Timing Question

Maybe it`s camera angle or my fading eye sight but the 3rd photo doesnt look TDC to me. The exhaust valve is partially open. Interesting camera angle too..............looks like the camera is on the piston at the bottom of the stroke. At TDC on any given cylinder your cam lobes viewed through your t...

Star stamp

Not really sure where to post this so I`ll put in under chassis. And not sure if I`m being paranoid but maybe someone can shed some light on this. https://www.ebay.com.au/itm/Ducati-Bevel-750-GT-Sport-860-900SS-Open-Star-Frame-Punch-also-singles/332829347814?hash=item4d7e2ccfe6:g:W9cAAOSw8m5bpCqx Th...

Re: 900 Darmah sputtering around 5000 rpm

Someone told me once the best way to solve carby issues was to start with the ignition. If your Darmah is Bosch ignition the first place I would start is the lead that goes to your left hand engine side cover. This lead runs from the ignition pick ups inside the side cover to the Bosch ignition boxe...

Re: 860GTS into Darmah

Thank you Kilmer for your kind offer and Ducadini for your advise. Sadly the monster I call employment prevented me from getting to the aforementioned Darmah frame, complete with swingarm, stand, rear guard and some pretty shitty plastics in time and it was snapped up for a paltry $500 by another be...

Re: Ducati 900 SS '82 | Front cylinder exhaust running hot

I`m with Gardner on that one. My SS did the same thing and it was the insulation on the ignition pick up wires that had broken down with age. Either way they are worth replacement if they haven't been done already. They will give issues eventually.........

Re: Cylinder base gasket - 900 bevels.

Maybe someone adjusting the squish clearance from one cylinder to the other??????? Can`t think of any other reason really...............were both bikes bought from the same previous owner??

Re: coat exhaust pipes?

I kinda like the bluing of the pipes, makes `em look tough I reckon. But I hear of some people using ceramic coating on exhausts. My understanding is that it has some sort insulating qualities and the surface temp of the pipe is lowered. I have no experience with it however, just passing on what I`v...

Re: 860GTS into Darmah

Thanks for the reply. No, crank is all still where it should be. Im looking at building a bit of a special. Basically along the lines of a 750 Sport but with no side covers and battery mounted under the duck tail. Bit of a minimalist look is what Im after. I`ve been offered a Darmah frame cheap and ...

860GTS into Darmah

Does anybody know if a 1976 860GTS engine will slot into an SD900 Darmah frame? While I`m picking brains is the frame geometry, as in rake, trail and wheelbase similar?
