SAI - do I have it?!

How can I tell?

Why do people disable it?

Pull the left side cover and if you have the plumbing in this pic, you have it...



Disabling has benefits....it stops header pipes from turning blue. However, with the triumph cruisers it doesn't matter because the headers are double walled and won't turn blue with or without it. The other one is that disabling it can stop popping when you decelerate. However, it's said triumph never enabled the SAI on the first run of Tbirds in '09, and the '10's and above don't even have SAI. So according to triumph no Tbird has ever run with SAI enabled. They show in the maps that they are checked, but i believe all that does is tell the ECU whether there is SAI installed on the bike so it knows to expect it for the malfuction light. So disabling it shouldn't do anything for the Tbird since no Tbird that has it is actually enabled. That said, i have plugged mine and found it to remove popping. That was when mine was a 1600. Since it's been a 1700 it doesn't pop much at all, and plugging the SAI now seems not to stop the tiny amount of popping left. One thing it does seem to do tho is make low speed cruising more stable feeling. So it does seem to have some affect even tho it's supposedly disabled. Maybe the solenoid somehow doesn't seal efficiently and some air gets thru even when closed, i don't know.

So thats my take, some fact, some educated guessing. If you have the plumbing in the pic you can try and plug it and see if you notice any affect. Just pull the upper hose off, put a piece of a plastic bag over the tube the hose goes onto and push the hose back on over the plastic to block air from going thru.

Thanks Daz, I have a 2010 1700 and I have it! Thats strange about it not actually working?!

I will give plugging it a try because I get quite a bit of backfiring.. Does a wimpy plastic bag really stop the air flow? seems like over time it will break apart and get stuck somewhere! Could I just pull the top one off and put a stopper in there with a clamp to secure it and leave the solenoid side open??

Well, the word is that triumph put SAI in it just like they do in all thier bikes but as the bike came close to being released they realized it was passing all emissions by such a wide margin it didn't need to have SAI. So they disabled it on the initial run then supposedly removed the hardware altogether later on. As to your's being a '10, I got mine in 6/09 and it is a '10 on paper. So when i say the removed it on the '10's it means those made for the 2010 model year. But thats the word on the net....could mean they removed it "at some point in 2010", who knows.

anyways, the fact the bike runs so much cleaner than they expected is why they supposedly never enabled it. I'm still not sure how true it is that none were ever enabled tho for several reasons.

Hey Dazco , that is really useful to know , thanks. I have just put my original silencers back on for the MOT test in uk which starts at 3 years old. I was worried it would fail as the TOR silencers I had on were clearly marked FOR OFF ROAD USE ONLY. So I am getting ready to re-map back to standard long silencers and could not decide which Tunecu programme to download and use. ou have solved it for me , thanks again.

Having said all that , after I put the original silencers back on I went for a ride and could not feel any difference in power or any sign of running lean. Is it really neccessary to re-map every time you change the silencers? Am I risking damage to the engine?

No damage. Don't worry about it, if anything, it'll run richer.
Having said that, I wonder if the emissions test will be hooped because of the richer tune hmmmmm

Ok, so that pic is gone... can someone please point out if I have it?

Also, does under your left side cover look as messy as this?

Is that screw hole (red arrow) always redundant, or should something be in there?
