    Reassembling the Eldorado

    If it doesn't have rust holes and cracks, I'd be interested.

    New 850T Owner

    There is no left or right on the wiring diagram, only upper and lower. The right cylinder points set has a red wire, which goes to the right cylinder coil. Do you have a shop manual? It's all covered in that. thisoldtractor.com/mg_manuals/workshop_manual_v7sport_750s_850t.pdf

    New 850T Owner

    If I remember correctly, the wires from the points connect directly to the coils on the 850-T. Red wire to right-cylinder coil and green to left. They connect to the - (negative) side of the coil. A white wire supplies power to the coils, it connects to the + side of one coil, and a blue/black...

    Reassembling the Eldorado

    Very nice. I do worry that the front fender will hit the horns under full fork compression though. It would be a shamed to mess up that shiny paint.

    Oil leak rocker arm spindle bolt. 1975 850 T

    Do make sure the bolts are not too long or too short. With a split lock washer, they should be 14 mm.

    Ambo sump full of gas!

    Even if the petcock was left on or leaked, the float needle should have prevented it from happening. Might be time for a carb refresh. I had a customer's Eldorado that the same thing happened to - it did not end well for him. Total engine rebuild.

    850 T GEAR BOX LAY SHAFT LH THREAD TORQUE

    That torque figure (115-129) is for the right-hand thread nuts in the clutch and output shafts, not the left-hand thread nut on the front end of the output shaft! If you look down at the bottom of the Gearbox list, you'll see the correct torque: "nut, safety" 50-57 ft. lbs. I've used that same...

    Reassembling the Eldorado

    The Guzzi VHBs are the only ones that the idle and main jets are the same size. This is because they're the only VHBs with accelerator pumps built into the main jet assembly. On all the other VHBs, the main jet screws into the "bolt" that holds the float bowl on.

    Reassembling the Eldorado

    Make sure all of the passageways are open in the carb body. thisoldtractor.com/moto_guzzi_loopframe_carburetor_rebuild_-__vhb.html

    Reassembling the Eldorado

    If you swapped the carbs left to right and it's still not running on the right side, then it doesn't sound like a carburetor issue to me. The "olive drab" floats start out as grey when new and turn color after prolonged exposure to fuel.

    BB TONTI REGISTRY and pic thread

    1990 California III Carenato Integrale. Puchased Labor Day weekend '23. Almost finished a total refurb. Plan to ride it to the National in John Day, OR. VIN: ZGUVWBVT2LM300054. 45k miles. Early 1969 V750 Ambassador. Owned longer than any other vehicle. Purchased in April of '97 with 36,360...

    Reassembling the Eldorado

    I use a Q-Tip chucked in a drill and fine valve lapping compound to polish the float needle seats. New float needles with pink/orange tip? Did you check to make sure the float wasn't filling with gas? New choke valve? Spring long enough to seat it well? Enough slack in the choke cables? I'd...

    Will a v11 lemans sidestand work on a 850T?

    I saw this on another forum, sidestand from a '94 Honda CBR 600. I mid-mounted one from a Kawasaki Z750 onto my V50 III.

    Locking plates for 1975 850 T rear main bearing.

    Since the cam plug will likely never be removed for any reason, JB Weld will be fine. It's what I use on all of the engines I build. Hylomar is my least favorite sealer of all time.

    Reassembling the Eldorado

    The pulley can be installed 120 degrees and 240 degrees out. Set the left cylinder to TDC and then install the pulley so that the "B" mark is aligned with the arrow. A long bolt with the head cut off is a good alignment stud to make installing the pulley and shims easier. Don't use bolts any...

    Reassembling the Eldorado

    I assume you've rebuilt the carbs? Did you replace the floats with the new white ones? Did you replace the choke valve springs with new? The reason I ask both of those question because both have been issues on customer bikes in the past. The white floats are rubbish - you really can't set the...

    Valve adjusters 1975 850 T

    If needed, I have plenty of good used early pushrods and adjusters, and am happy to share.

    Reassembling the Eldorado

    No, those "velocity stacks" are for early Tontis and will not work. I have a bunch of good, used, original Loopframe 'stacks.
