Fuel Injection
|
Just spent over 10 hours this week trying to get the sidecar tug started
(K100RT). I replaced the fuel pump and removed the injectors and had them
serviced, put her all back together and no go, plenty of spark and no fuel
getting through. I suspected the fuel pressure regulator was jammed open not
allowing pressure to build to the necessary 36 psi. I purchased a fuel
pressure gauge and found a perfect 36 psi at the injector manifold. Clearly
I had an electrical problem not pulsing the injectors. I checked the fuses
all good, pulled off the tank and found the injector control relay not
switching in, pulled the tank on the K1100LT and raided the injection relay
for a replacement test. Still no go, in desperation I pulled the fuse for
the relay (which also served the dash lights, and stop lights which were
working) found it had some surface corrosion and changed it for a new one.
SUCCESS the engine fired, 10-12 hours work to find that the fuse had enough
contact to run the lights but not to activate the fuel injection relay.

At Xmas, I presented my niece with a CT90 that I'd rebuilt for her as
a paddock bike.
(I'd picked it up on hard rubbish day in Albury, then spent about $200
on a basic top-end rebuild).
I'd stripped out the ragged remnants of the wiring loom during the
rebuild, so it just had the basics for running the ignition. On the
big day I arrived at my parent's farm, and just had to bolt on a
sidestand and rectifier to be good to go (I'd been running it as a
total-loss battery system). Poor little Emily sat next to me for 3
hours, helmet in hand, until I finally tracked down the subsequent "no
spark" problem to the spring inside the fuse holder being too squashed
(cylindrical glass fuse).
She had fun with it after that, though. ;-)

My R100GSPD is much simpler.
Getting closer to having 3 wheels on the road.

You should consider replacement of that fuse with a reasetable insert .
