Secondary Air System Removal?

Just a thought: Has anyone tried removing the secondary air system from the 1200 and running without it? The bulky box and hoses on the bottom of the air chamber are a real PITA when removing or installing the carburetor rack.

Our neighbors to the north do not have that on bikes made for their use. Some were posting about removing it a while back. Start here. viewtopic.php?p=140213#p140213

Well I'm running the 1200 engine with a single carb and put a gasoline grade hose looped to each other and no ill affects I know of so far. Honestly I have no idea where they connect to on the stock rack and what affect disconnecting them would have.

Haven't looked into this yet; however, owned a 2007 Suzuki C90T with the PAIR system. This was a secondary air system as well designed to provide additional air into the exhaust so that the emission standards would be met. As with the query here, a lot of owners took the system off. The biggest plus for removing the PAIR system on the Suzuki was that you got rid of the big piece of chrome cover from the right side of the engine. I never did the removal and even with it on got excellent fuel economy on the highway.

i certainly have the system gone on my bike ...with the single weber carb and early heads on LOL no place for it now ...results bike will haul ass :BigGrin:

One of the members did it here... I received a set of blank off caps and plugs from him to do it to my 84 1200, but I over-heated it first. Let me find the thread...

Here is the thread that discusses it... https://classicgoldwings.com/forum/viewtopic.php?f=24&t=9287&hilit=secondary

One thing it gets rid of it the anti-burn valve so you lose the backfiring on declaration. That is the one reason I wanted to do this.

For Bronko37: Do you still have the drawings used to make the plugs back in 2015?

If so, would you post them to this topic so I can make sure my measurements are as accurate as possible? :builder:

Thanks

Don't need the drawings after all. My son made four of the plugs for me tonight. I installed them and the card rack an hour ago and the PITA factor decreased significantly. She starts better, but #4 carb still isn't getting fuel to the cylinder because the exhaust pipe isn't getting hot. Got good spark and the carb bowl has gas, but nothing getting into the cylinder. The enricher valve moves, but apparently nothing is getting into the air stream.

I suspect a plugged jet somewhere, but haven't found it.

Found the plugged jet and she runs good. She's a beauty, but I have two other 1200s registered and insured, so she needs a new home. Take a look at Craigslist St Louis if you're interested.

hmmmm i bet it is nice

Quick picture

Took of carbs to replace choke cable, and decided to plug the secondary air injection system. Took measurements and trying to find a lathe I can turn the plugs on, but those of you that have done this, what have you used?

Is there a part used on non California 1200's that was used? Or is it on all?
If you made you part what material did you use? And do you have dimensions (to compare to mine)?
Did you find another material that worked fine without making the plugs?

Any other ideas, or cautions?

My son milled down 1" aluminum rod to match the secondary air system nozzles. Hasn't seemed to have any effect on running. :builder:

Yeah, I am not expecting any change in performance, just a cleaner install / uninstall. I have a friend whose making the parts for me, he will use what he wants...

Just looking for data to consider. 1' round stock is a great place to start since the originals are .780, though .75 (3/4) probably works fine.

If anybody cares, the bike sold today. However, I also have an 86 Aspy that needs a good home - $2500. Original paint, 28K on the odometer and the original AM/FM/cassette player still works.

I showed both bikes to the buyer; he had a tough time deciding which one to take home. I suggested both, but he finally decided on the Interstate because his wife thought it sat better. Happy wife, happy life. arty:

Now I'm back to working on the 84 trike conversion. The secondary air system will be removed from it also. :builder:

sounds great ...you sold the bike ....now get to work on the trike ..ive got plenty to do on my bike also

Congratulations on the sale of the interstate. :clapping:
