Smart wife! (They usually are smarter than the husbands. So I have been told...numerous times.)

It is variously called the "coasting enrichment valve" or "air cut-off valve" or "transient enrichment valve". When the throttle is closed, there would a transient lean condition, causing popping upon deceleration (coasting). This device enrichens the circuit to prevent popping. The diaphragm can be damaged by aggressive carb cleaners and the diaphragm can also develop holes. The result will be a vacuum leak and popping. Air Cut-off how it works.docx

Spring rate for rear shock on the Standard XVZ is 481 lb/in. (non CLASS shock). Spring rate for the rear shock on the Royale XVZ is 406 lb/in (CLASS shock). Your 1985 is a STANDARD? (No CLASS?) Since there was no 1985 XVZ12 Standard sold for the US market, it must be a Canadian model, or the original CLASS shock was swapped for a non-CLASS shock. What is the VIN for the 1985? For the 1988? Non-CLASS rear shock: CLASS rear shock:

I made a pilot screw "adjuster" that allowed me to make adjustments to the air/fuel mix while the Venture is nearly fully "dressed" (i.e. with the fairing lowers on the bike, but with the side covers removed. One cannot access the pilot screws with a conventional screwdriver when the lowers are installed).

Generally, we consider 2¼ to 2¾ turns out as a baseline. Yes IN equals leaner, OUT equals richer. Read the pdf I attached to my previous post.

Yes, that is the pilot screw (air/fuel mixture) but, that is not the synchronization screw. The synch screws are here: Synchronization ProcedureCarb .pdf

A "redneck repair" or "roadside resourcefulness", depending on your level of OCD.

I call them little E-clips "Geezus rings", as in "Geezus, where did that **xyz**ring (clip) GO?":big-grin-emoticon:

Injecting cleaner into the pilot screw (air/fuel mixture) orifice won't get cleaner to pilot JET. The path of least resistance would send the cleaner straight into the carb bore. What you CAN try is to inject cleaner into Pilot Air jet #1 . That path is a relatively straight shot to the pilot jet.

In addition to what Luv said, follow the leads from the float rheostat to the CMS (Computer Monitoring System). Clean and check any connections, including the main connector on the CMS. Failing to find any inconsistencies in the connections and wiring harness, you must suspect the CMS circuit board.

In addition to the E-clip there should be a plastic bushing and plastic washer.

That Klein screwdriver you linked to is what Carl is recommending. He made a 3/16" cabinet tip screwdriver from an ordinary "flared" tip screwdriver by grinding off the "flare". There will be no grinding involved if you buy a CABINET tip screwdriver. You are not to be working the screwdriver very hard, so a cheap cabinet tip 'driver will suffice. An example of a 3/16" Cabinet tip driver: Compare it to a "flared" 3/16" driver: The flared tip will not enter the pilot screw recess, (too wide).

"Messing" with the suspension on a Royale is as simple as pushing a button. If you select the maximum (HIGH) setting on the CLASS, it should remain at that setting "permanently". (Provided there are no leaks).

Really cheap even with the rather high shipping charge. But, just so a prospective buyer is aware; this hitch assembly is missing two important components: Clamps that secure the hitch to the saddlebag guards. Item number 13 on the installation instructions.

To me this sounds more like a fuel system problem. Ignition and electrical tend to be instant and/or intermittent, but not a gradual loss of power and slow death. The throttle issue is another fuel/carb indicator.

Thank you for your contribution. Your entry is the first for that particular Venture into my database. I have no further information, other than it IS indeed a 1989 California market XVZ13DWC Venture.

So? Where did the fuel go if not into the engine?
