 | Regarding Chrome Re-plating: Marc and Margie Connelly '93 1500 Aspencade-Black
of course- Lake George NY =20 I have done several restorations of different
sorts. If the part was available new it was all ways less expensive to buy it.
= If it wasn't then re-plating was the only alternative. With the large
availability of parts for Gold Wings I would think = replacing would be the
way to go. Also The wait to get your part back has been a long one in most of
my cases. Marc |
 | Cleaning the engine oil screen-
Drain the oil. Remove the right head pipe. Loosen the bottom engine mounting
bolt next to the oil screen cover. Remove the four oil screen cover securing
screws. Use an offset screwdriver or a chisel to remove the front oil screen
cover securing screw. (unscrew it, don't chisel it off!) Flex the frame next
to the lower mounting bolt (about 2mm) to facilitate removal of the front oil
screen cover securing screw. Remove cover, screen. slowly pour 1 qt of clean
oil into the fill to flush any particles from clutch towards the screen. Reach
in and scoop out any loose particles. reverse for reassembly replace front oil
screen cover screw with a hex head bolt about 3mm shorter than the original to
facilitate removal next time. Retorque the lower engine mounting bolt to
55-650 kg-cm or 40-47 ft-lb US, But not imperial. make sure
everything is back on. (torque oil filter bolt to 270-220 kg-cm, drain plug to
350-400 kg-cm) fill up the engine with new oil. (3L of Honda 4-stroke oil or
API SE, SAE 10W-40 or 20W-50) Run for 5 min. (The engine, not you) redo
everything 1 more time, changing the oil filter. |
 | Cruise control
Sorry I didn't keep all the individuals who contacted me for these
instructions so I'll use the list, sorry list. Here's how I mounted an
automotive electronic cruise control to a 77+ GL1000. I haven't put these
instructions on my web page because I'm waiting for either a purchase of a
digital camera or someone who owns one who would take pix for me of my bike at
the various stages of installation (or at least how I did it). Items needed
(not including tools): - electronic cruise control, I bought the dash mount
control but a turn signal mount should also work. - 1-1/2 dia PVC pipe, 6 inch
length - end caps for 1-1/2 dia PVC pipe (2) - one way valve, must fit vacuum
tube - "T", must fit vacuum tube - pipe thread to vacuum tube fitting adapter
- 5mm carb synch tube/screw Actuator and throttle cable attachment: Remove the
faux tank. Mount the actuator on the back-right side of the radiator cowling,
cable up. Route the cable along the front side of the air cleaner then follow
the throttle cables on the left side of the air cleaner to the carbs. Attach
the throttle cable to the linkage operating the right side carbs, there wasn't
enough room to attach the cable where the other throttle cables attach. Attach
the throttle bracket to the left side frame. Vacuum connection: Replace the
5mm screw in the right front (#2?) manifold with the carb synch tube/screw.
Attach the vacuum tube to the 5mm screw, may need hose clamp. Measure and cut
vacuum tube to length and attach to actuator. Glue both endcaps onto the PVC
pipe. Drill and tap one of the endcaps for the pipe thread to vacuum tube
adapter. Screw the pipe thread to vacuum tube adapter into the tapped hole.
Mount PVC pipe to frame next to actuator, adapter down, with cable ties.
Attach excess length of vacuum tube to PVC adapter. Cut manifold to actuator
vacuum tube where excess tube crosses and install "T". Cut excess vacuum tube
at "T" and attach. Cut manifold to "T" vacuum tube and install one way valve.
Speed sensor connection: The cruise control I purchased did not need an
separate speed sensor, all sensing is done at the right side coil. Command
module mounting: Mount command module on the left handle, where ever is
comfortable. Electrical connections: Power wire is connected to the black
wire. Ground wire is connected to the frame ground just in front of the coils.
Brake wires are connected to Green with Yellow stripe wire just outside the
connector to the Resistor assembly, and to the White with Green stripe wire
near Buzzer. Outside of testing that is the complete installation for the unit
I purchased. Units you purchase should be similar. Ray 77+ GL1000 CWC 423 MRF
