Re: completely remove starter assembly flywheel etc...

Yes, you can run with just the flywheel. You really don't even need the flywheel but your idle quality may suffer.

Re: Overflowing Carb

It's unlikely the grit came in through the air filters, most likely it's from the tank. Very fine rust particles can make their way through the carb screens and will collect in the float bowls. The thick oily stuff is the remnants of whatever fuel was in it 10 or so years ago. Sounds like it is time...

Re: 900 Darmah sputtering around 5000 rpm

It would be prudent to remove it before tweaking it.

Re: 900 Darmah sputtering around 5000 rpm

You need to check them with the float needle just closed and not compressing the little springy thing on the float needle. The float itself should move freely on the spindle. Scum can form on the spindle if the carbs were stored with fuel in the float bowls and it evaporated over time.

Re: 900 Darmah sputtering around 5000 rpm

What Lumpy said, but also check that the float levels are correct. You could be running out of fuel under load if the float level is too low. In addition to a possible clogging petcock have a look at the filter screen under the carb banjo as they can fill with rust and become blocked.

Re: Neutral switch paradox

The late 750 used the dash that they had at the time[860 style]. There is no provision on/in the cases for a neutral switch. The late 750's were sort of produced to use up the remaining stocks of round case engines. The early 860's used a brass cam on the shift shaft where it exited the selector box.

Re: Overflowing Carb

There is only one way into the carb for the fuel to enter, through the banjo and into the passage going to the needle and seat. The check valves are both fed from the float bowl, after the float needle. If you have the plastic banjos on the ends of the fuel lines they may be cracked. It only takes a...

Re: Overflowing Carb

It's usually dirt in the float needle/seat assy. A little speck of junk will hold the needle off of the seat enough to cause a flood. Sometimes the float can stick on the pivot pin if the bike has sat for a long time and the fuel evaporated away. Sounds like time for a carb clean.

Re: Drum Brake sprocket carrier re-assembly

#25 is the spacer between the bearings in the hub,the stub axle that holds the sprocket carrier butts up to it when the wheel is installed.

Re: Drum Brake sprocket carrier re-assembly

Neither the 750 or 860 parts manuals show a spacer between the bearings in the sprocket carrier. The bearings aren't pinched together when the axle is tightened because the spindle they ride on butts up to the the spacer in the wheel hub when the axle is tightened. The sprocket carrier floats on tha...

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

If the wiring proves to be OK. try switching the Bosch amplifiers cyl. to cyl. As reliable as Bosch equipment seems to be, they are over 30 yrs. old and as we used to say in the old days "never trust anyone over 30". I've replaced about 4 of them in the past couple of years for various running issue...

Cross torquing the crankshaft can pull it out of true. Not so much the ign. flywheel as the taper fit doesn't need much torque to hold it securely(too much can damage the crank and/or flywheel)the but torquing alt. rotor holding the flywheel nut or torquing the clutch hub by holding the alt. nut may...

Re: set screw size for front brake lever on Darmah

That little allen head screw [set,grub?] in the lever is either 3 or 4 mm x .7 or .75 it's there to adjust the lever free play. Unusual for them to fall out as they are loctited in and hard to move without rounding out. It looks like the kit Craig shows includes it.
