I've seen the pros and cons of a desmog, and I'm inclined to leave mine. The mess of hoses seems pretty unmolested (all the clips and clamps are in place), but that probably also means the hoses are original. Regardless, I've got some stuff to clean up when I pull the gas tank. Replacing hoses while it's off shouldn't be too hard.

I've de-smogged my KZ1300, but that was mainly because the system got in the way of EVERYTHING whenever you wanted to do something. The Valk system seems a bit more out of the way, and if it ain't broke, don't fix it. And I'm not inclined to go chasing things in circles, especially with a drilled exhaust.

This is how things began- the removal of the non-working air horn and compressor, and cleaning up this wiring into the starter solenoid:

This is how things ended:

So.... this is the order of events.

--Wiring bodge-job properly soldered and heat-shrinked.
--Put right sidecover back on.
--Already-broken center panel tab repair fails.
--Decide to pull of gas tank to make removal of center panel easier.
--Vacuum lines 100% original- one on petcock practically glued to barb.
--Have to cut vacuum line to remove tank.
--Remove center panel.
--Sigh, shake head, re-order all new vacuum lines.

The only way that I’ve found to manage those hoses when removing or installing the tank is a pair of 8” curved hemostats.

Yeah, even with the tank off, I couldn't get the vacuum line off. I'm probably going to have to cut it off the petcock. On the upside, replacement hoses are in the mail, due by the end of the week. I'll probably grab a new air filter too while I'm at it. I hear getting the airbox back in can be a pain in the backside, but I've read up on a couple techniques. I guess we'll see.

On a lighter note, I am in LOVE with the design decision of the coil placement. Two of them being mounted vertically above the engine, neat and tidy, between the rear engine mounts. But what's this? No room for a third? Uh... just bolt it up.. somewhere. Anywhere, I don't care. Bam, above the left-hand carbs! Sure, why not? :lol:

Small update- I'm probably not going to get a whole lot of work done in the near future. As a result of playing with my nieces on Easter, I managed to roll my ankle and sprain it pretty bad. But hey, at least it was over a old college sports injury, so that had to help, right? :IDTS:

In any case, we're back to the "theoretical" bike work. First off, I think I'm moving the saddlebags forward. They'd look much better centered on the back wheel, I think. Same with the rear rack. However, this means replacing the saddlebag mounts I have, as the bags are bolted as far forward as possible without the racks being visible. Because every set of support bars I've seen angle backwards, I get the feeling I'm fabbing up my own.

On the upside, I've got a new air filter and vacuum lines on. The lines looked pretty good, but all the caps were cracked. The idle and rev in the garage seemed like an improvement, but an on-road test will have to wait until my bum ankle decides to shape up. Still, I'm looking forward to it.

Progress is progress. There’s always something. I found that all the hype and complaining about getting the airbox on and off was exaggerated a bit. (My opinion). I felt it was a nonevent. Mine has been off several times.

I de-smogged mine the same year I got it. In my opinion, it just removes another potential future point of failure. Actually many points of failure. Vacuum leaks are insidious little devils. The biggest chore is plugging the holes in the heads when you pull the airlines out.

Sorry to hear about the ankle.

I know, right? Half the airbox threads about the Valk are how much of a pain getting the airbox in and out was, and it was one of the easiest parts of the job. I suppose things depend on how flexible the intake runners are, but even still it's not like a job that needs three hands. Heck, the hardest part for me was getting the gas tank overflow tube back on. (How they managed to hide it under a frame gusset, I'll never know...)

I also finally got a service manual in the mail, and apparently you can unscrew the plastic petcock lever extension WITHOUT having to remove that cotter pin? I've definitely been doing THAT wrong...

Yeah, I remember the first time I took the tank off. Luckily I saw the hole in the petcock knob and thought, I think I’ll shove a screwdriver in here and see what it does. Once I get both tank mounting bolts off and the petcock know unscrewed, I just lift the rear of the tank about 4" and remove the drain hose with hemostats, then lower the tank back down and use the hemostats to remove both the large fuel line and vacuum hose from the petcock from underneath. Then the whole tank can be pulled off. Takes about 2 minutes.

But you probably know all that by now. Nothing like doing it to learn it.

Sad thing is that I knew about the screw inside the petcock lever- it's just for whatever reason, the cotter pin wouldn't let my screwdriver get a straight enough shot at the screw to get it out.

Guess I just need a better screwdriver...
