Also find out what those ports are that the 1200 intakes cover on each side of the intake. I don't have those on mine, so don't know what they are or if/how you can block them off.

I did it again. Instead of hitting the back button to kill a linked page, it kills the site. Never been on a forum that does that and I'm forever having to retype an answer or question. :x

Now re. your post, that's part of a fresh air insertion system that pushes fresh air into the exhaust. As you can see by the link, the myriad of hoses under the carbs are a great source of vacuum leaks down the road. My Valkyrie had it also....for about two months. ;) Those hoses run on top of the hot engine, creating headaches after a few years and are a real PITA to get at. So most Valk owners when they get to the point of pulling the tank to service/replace the intake filter, they also pull the airbox and remove all that crap. If you look at items #7 & 8 on the link, those plug into the head and are held down by the intake elbows. If I go with the 1100/1000 elbows, I would simply remove the hose at the inner end of 7&8 and fill with JB Weld, then cut a small piece of SS long enough to reach from the nearby elbow bolt to hold them in place.

Oh ok, thanks. I've seen those connected up to be used as manifold heat on some single carb manifold designs and just assumed it was probably coolant lines. I guess hot air would serve the same purpose to heat a manifold, just didn't think that's what it would be.


I have to order a new carb. I now officially give up on this leaking empi piece of junk. Stupid thing leaks nearly every drop from the bowl after a few days with the fuel shut off. If you forget to shut the fuel off, I bet it would leak a whole tank worth in under a month.
I guess after a few bowls of fuel my new oil is now toast too. This sure sucks.

I just happened across this eBay listing while looking for a new carb. It seems to show that 1100 intakes do work on 1200 heads.

83gl1200 in regards to the manifold you viewed , i pulled my 84 service manual out and have been reading about those secondary air lines and everything else that connects all the way to the epa and it tickled me. you must take it to a stealer to have it come up to par with a perfect vehicle. i noticed in the add that it does showcase a 1200 yet the other pics are of an 1100. i also noticed the air tubes on the 1200 not connected. in one 1100 pic i see a tapped water fitting that i am sure would connect to the manifold to prevent icing. trickery,trickery at least i got a good laugh out of it. i can tell all of you more about me and those air lines on a gl1500 i just rebuilt and what the dealer told me to do with them.

Yes I noticed that the manifold heater on his pics only covers two runners not all four, and is only connected with tack welds, so I don't think the designer is very bright or that the manifold would work properly at all. But it did show 1100 intakes bolt up to 1200 heads and that's all his ad was worth.

We don't have any epa or deq testing of motorcycles here where I live thankfully, or none of these single carb conversions would pass.

We don't have any vehicle checks in Florida either, what a waste of time and money it was a number of years ago when we did have it. Statistically it made no difference in accidents, injuries or deaths, and cost a bundle for the state to operate. I forget just which governor did away with it, but when he made it part of his campaign issue it went over in a big way.

As for the intake elbows, I've been corresponding with Roncar who lives about 60 miles from me. He has some 1100 intakes he'll sell me and I can pick the ones I want. Should make a nice ride down on the bike. I'll have to use one of the sync ports for the vacuum line for the ignition control module, shouldn't be a big deal.

We have deq and inspections here for everything but motorcycles and commercial trucks. Its a real pita, and they could have done more for clean air if all they tested were the commercial trucks, but I think its a make work project more than anything. I can't say more than that because some moderator here apparently doesn't allow adult conversations on political or religious topics. My previous post was edited by them and locked. It may be time for me to move to another board myself. I prefer freedom of speach and there is none here.

thats funny 83 gl1200 i asked you a question in my original post
so i ask again how much was the shipping? the reason i ask is
my price for s&h on the manifold is less than 4 side feed tees
the 89 gl1500 has performed flawlessly with the 34pict3 carb and
i didn't mean to lie to anyone but observing the posts' i looked
at my gl1200 a little more carefully and will hopefully have all parts
here first as it is my favorite ride! nekkids are just my hotrods,fun!

I never saw you ask about shipping. Are you asking how much I paid for shipping when I bought the 4 gl1100 intakes off ebay? I don't know. All I remember is they were 20 plus shipping. If you're asking about how much I paid for shipping from flexpvc for all the plastic parts I also don't know, I just remember the total was less than $40.

I have a great memory, it's just that I'm stoned half the time and it makes me forget things, like how my memory actually sucks.

$20 plus whatever the new shipping charges are to whoever wants them is all I'd ask for from the intakes. Not the previous shipping to me that I can't even remember.

To John, The early model intakes will bolt up to 1200 heads, but the holes aren't aligned very well. The bolt holes are slightly off, and the charge hole will be blocked partially. It might leave a ridge to catch fuel on.
Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.
