Re: Silent Hektic Ignition

Being a squarecase the Dyna ignition Bern suggests won't fit your bike. You could try swapping the coils and see if the problem goes to the front cyl. I suspect [because it has bitten me before] that you might have too wide or too close clearance between the ign rotor and the pickup. The ignition is...

Re: Round case indicator lights question.

It has been a long time but I believe the lenses were just little dots of colored plastic just pushed into the ID of the light housing. You might try finding a hole punch or a piece of tubing with the right inside diameter and make your own. Grind a bevel on the outside to make a sharp edge and cut ...

Re: Ducati deodorant

Obviously they are targeting the late superbike owners. It describes an oriental, fruity, feminine scent suitable for daytime wear! Definitely not for we macho bevel owners! We need a bacony, sizzling fat, smokey, oppressive cloud surrounding us.

Re: Right hand casing getting hot

There isn't anything in the cover other than the alternator stator. It could get warm if the charging system is working really hard, you might want to check the output voltage. It shouldn't be more than about 14.5 volts. If it is much higher the Reg./rectifier could be bad. My suspicion is the horiz...

Re: 860GT piston ring gap orientation

That illustration Steve has provided is sort of confusing. It shows the piston pin center line as running fore/aft and if so that places the top and 2nd ring gaps on the thrust faces. That may be acceptable for an inline engine with a long piston skirt but it goes against all the recent illustration...

Re: Starter issue

Start by removing and inspecting/cleaning both positive and negative battery cable connections. Corrosion at the terminals can give the symptoms you describe. Also look at the cable where it goes into the terminal, if the copper wire is greenish or black or has a white powdery residue on it it is ti...

Re: Looking for 750GT Turn Signal Switch

I may be mistaken but didn't they use the Lucas switches like on Norton/Triumph? Some of those Lockheed master cylinders had housing with a lever and two buttons that screwed onto them. I know Laverda used the Lucas switches briefly in the early 70's. I imagine the Aprilla switch Steve has listed co...

Re: Darmah rear brake linkage: clevis pins

I have made my own by cutting a bolt with an unthreaded shank and drilling a hole through it after cutting it to length.If you don't like the hex head you could probably find a Phillips or use a button head Allen bolt. The pins aren't hardened or anything special metal wise.

Re: 860GT base gasket question

A thin smear of just about anything will seal it ok, If the copper gasket hasn't been used before it is likely soft enough to seal without any additional sealing compounds. Due to the relatively large crankcase volume and lowish revs the bevels don't seem to build the crankcase pressure and leak lik...

Re: 860GT valve seal confusion

If my memory serves, I think the springers all had the cap type seals and the desmos o ring type was superseded by the cap type in '74 ish. I used to have some Ducati service bulletins that mentioned the change along with the recommended relieving of the bottom of the closing rocker to clear the sea...

Re: 73 GT Alternator replacement options

I suspect the reported unreliability of the ST2 alternator stems from over accessorizing the ST2 for touring, i.e. heated grips, driving lights, heated suits, gps, etc. all running at once along with the marginal connector security Ducati is famous for.

Re: 73 GT Alternator replacement options

If you can find one, the ST2 alt. rotor by itself is supposed to upgrade the output to acceptable levels.

Re: custom/modified rear intake manifold

Craig is on the money. The 40mm Dellorto carbs don't really add anything by themselves, you need cams, pistons, and port work for noticeable performance gains but doing so will affect the tractability. The 40mm carbs are pretty crude and don't atomize the fuel well at low air velocity and getting th...

Re: Starter issue

Follow the heavy lead from the starter, it will end at the solenoid. Can't remember where it is located on the Darmah, probably mounted under the battery tray. If you drill out the rivets holding the cap on the solenoid you can get to the contacts. They most likely are burnt and the surface is rough...
