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.



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 .

 

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. ;-)
