We desmogged the Green IS today...

[Jabba]

Lost all this crap.

I could tell it was better from the initial start up.  And it runs WAY better now.  There must have been more wrong than I thought... but it's all good now.

[Farther]

Did you use a kit or site fabricate stuff?

[Jabba]

I used the RedEye Shiny DeSmog kit.  I am a little disappointed in the "hold downs" they provide.  I had to use two of them, but I was able to reuse 2 stock ones where you can see them and it is OK. 

The bike runs WAY better now.  Now I need to desmog the STD.

[Farther]

I'm thinking there is a de-smog in my future.  I have been carrying the XF6 plugs and block-off plates for several years in my saddle bags.

[Jabba]

I am glad I did it.  I was having some issues though... and I have a little 'tick' in the STD too that I can't figure out what it is...

I plan to desmog that one soon too.  It was not that bad really.  For me... getting the block off plates installed was the worst part.

Heck, it has to run better ! Look at all that junk you took off it, its a whole lot lighter now !   

[pancho]

I wonder what you see as it running way better...  I mean if the system is not working correctly (PAIR valve staying open for lack of vacuum) you will get a lot of popping on deceleration, or if there is a vacuum leak there will be obvious problems to the affected cylinders.....  what did you notice as the difference???   

my first thought as to the "little tick" on the STD would be a valve adjustment..????

Mine always had a little tick and still does. Valves adj and desmogged.

I had some carbs goo'd up.  For sure.  But it still had some hesitation and so forth.

On the STD I have adjusted the valves recently.  I thought it was an exhaust leak.  THAT's what it sounds like... but I have become convinced it's really a vacuum leak.  I am gonna START with the desmog.  It's easy.

I have yet to understand the desmog process that some go through or why it's done. My I/S ticks and runs great, the Tourer has a tick and also runs great. To take the time to remove all that chrome and spend money in the process, on what can be done by removing the pair valve and  capping the outlets of the reed valves and capping the remaining vacuum piglets at the intakes, with the exception of the #6. The last thing would be to cap the inlet to the air box and you have done the same thing without the hours of cutting and removing the vapor tubes. JMHO

[Jabba]

I only had to cut one tube...

And the whole process took just a little over an hour with two of us. 

And the kit was $44.00.  I LOVE having all of the rubber GONE.  Maybe your route does the same thing... but my brain is tired and I didn't want to THINK too much.  I wanted to be able to follow directions... 

I spend ALL my time thinking about crap and figuring things out and making decisions... and it was therapeutic for ME to disengage the brain, and follow simple instructions.

And it runs better now.

Now you are getting to the heart of the issue.............   I started to do a desmog a couple of months ago just because I was new to a Valkyrie, had mine all apart, and that was one of the things "recommended??" As I started to take things off I felt as if I was pulling teeth from a good looking woman and decided to find out how the system works and what the problems with it were. I discovered that the only downside to leaving all the hardware intact was if you did no maintenance and developed a vacuum leak in the hoses or PAIR valve. I disabled the system by removing the vacuum hoses from #2 and #4 and capping them, and plugging the air intake in the airbox with an appropriately sized hex head bolt to eliminate the burning of raw fuel on deceleration and causing extreme popping.... actually kind of cool, and I can always get it back by removing the bolt.....  I do not understand the desmog concept as the rest of the bike requires maintenance.

I did the desmog when I was switching out my slow jets so it was wide open to see everything better . I went with the shiney kit and just cut the 1 metal tube like most do . did the pilot adjustments with fresh o rings everywhere all went smooth and I did my first decell on a test ride and it popped for the first time ever <stock pipes> kinda shocked me that it did that but with some tinkering and a good set of hondaline 4 guage vac setup it got it to stop but last week I got hold of a like new set of 2 brothers carbon fiber pipes with the crossover lets see what it sounds like now update to follow....

[salty1]

Jabba you might want to top off the desmog with synchronizing your carbs. It just fine tuning IMO. My desmog allowed plenty of room for the Dan Marc install and eliminated a lot of junk or future potential problems.

[cashman]

I would be interested in coming down when you do the standard to be a part of the process.  I have been contemplating desomg on my IS and would like to see it done!

A little over one hour? You must have left the tank and intake air box in place?

And it runs better now.

No... Clearly you forgot to use the official sarcasm font.

There were two of us... and we have been thru the tank and airbox a few times.  The airbox is NOT bad if you truss up the rubber tubes when you reinstall it.

I will say that when I decided to leave the smog hardware intact, I had to replace the six pieces of tubing on the reed valves. they were deteriorated and not sealing properly. 16 years old and subjected to heat,  so there was a bit of maintenance required to keep it.
