Howdy howdy Guzzi party people! Thought I’d post about today’s adventures inside a used Norge. This is a long one!
I got started today with the intention of simply doing something with the stepper motor. I wasn’t sure what, but I’d read plenty.
Got the tank off…and that’s where the scope started to creep. Anyone who works on stuff for a living or used to, probably just had a bit of a giggle.
1st thing I noticed was the red plastic elbow had been replaced with a brass elbow. A CRG stainless steel quick disconnect had then been added inline further down stream from the pump.
All had been done using pressure rated fuel line & Öetiker clamps, so not half assed….except that the side of the quick disconnect that has the fuel shut-off was on the throttle body side of that equation.
To top that off, there was no real rhyme or reason to the lengths of hose used. Ideally one would want the quick disconnect positioned for easy access for tank removal. That wasn’t the case either.
2nd thing I noticed was neither hose for the evap emissions system was connected. The wire clamps were too far from the nipples to have been on for who knows how long.
Removing the airbox to get down to the stepper motor, I made the decision to to plug the line from the complete absence of any kind of oil vapor/collection inside the airbox.
While in that process I noted a few more things. 1st (3rd?) the filter had not been seated correctly and the ridge that forms the seat for filter had cut into the filter rubber.
2nd the hose that goes from the rear of the airbox up to the breather box had been installed the wrong way around. Finally, there were 2 different screws holding the breather box to the airbox. (Anyone else find that annoying?)
Then, as I started to remove the airbox it became apparent that the left side airbox rubber was not completely seated on the throttle body.
Airbox out finally, and the hose to the stepper motor was secured by a zip tie.
Shoved a rubber plug into each end of the hose and secured the stepper motor end with a clamp. Sprayed some ACF-50 into each of the connectors I’d removed already and then did the same for the stepper motor connector.
Beginning reinstall of the airbox I rerouted some of the hoses & electrical that were poorly routed. I’m certain by whomever had been in there before. No way the factory was that messy.
Turned the filter over and seated it correctly inside the ridge. Fit the cover and made sure the filter fit inside that ridge as well. Replaced the mismatched screws for the breather box and flipped the hose to it around so it followed the contours of the airbox.
Right about then I realized I’d need to re-do the fuel lines as the the airbox reinstall kept fouling on the line/quick disconnect fitting. Airbox back out.
Removed the Öetiker clamps and swapped the line from the throttle body with the one on the tank. I didn’t have any pressure rated line handy else I’d have cut the lines to length before applying new Öetiker clamps. I’ll have to go back in there again and sort all of that out to my liking. It works as is for now though.
At least when the quick disconnect is disconnected the tank doesn’t pee fuel all over the ground now. Airbox back in. Evap lines connected. Tank installed.
Started the bike back up once the tank was installed to see what effect plugging the stepper motor hose from the airbox had.
Dash showed 57 degrees when I turned the key to “on”. Engine fired right up but did not go into a high idle sequence. Idle was right around 1200 RPM and did not change. Took a test ride. Engine seems much happier.
After fire popping on deceleration is greatly reduced. Acceleration seems much smoother also. Unsure how well it will start when temps dip back down to the 30s but the engine seems happier.
Will definitely have to get back in under the tank & airbox at some point to tidy up the fuel line arrangement. Also noted oil seepage from somewhere under there.
It’s running down the front of the engine between the alternator belt cover and the left cylinder. Unsure of the source though it seemed centered around some sort of sensor. Have not as yet done any research on what it is exactly.
More when there’s something further to write about.
