so your bike ran like crapp with the TPS disconnected? 
Not like crap but noticeably worse in respect to backfire and off the line response. It felt like it wanted to die on takeoff unless I realy throttled up.
Normally its smooth as glass of the line and only backfired a couple times on startup but NEVER while riding or on decel.
Thanks Z. I leave mine connected. I dont really have any issues either. Proper set up I guess...........

Erwin, give it a shot. Its only a plug and if it makes a positive difference then you know.
If it makes no differenc then there will be two of us that had a "worse result" result.

I've been looking for a pic of where the tps is located but can't find any. From what I've read the TPS can be disconnected by unplugging some wires which are positioned between the carbs and that they aren't that easy to get to. So is that enough info for me to look for and then be sure that I am disconnecting the right wires? I've also had a look at this eliminator kit so if I do find my bike runs fine without the tps, am I right in assuming it'll be self explanatory in how to I can fix this kit to the appropriate spot??? thanks to anyone who can answer these questions but I just wanted to get it sorted in my head before pulling plugs that I don't know about. Btw, I've looked at both my manuals and there wasn't enough info in them for me to work on. cheers Staffo

Staffo, The TPS is that black thing on the throttle side of the carbs. It has wires in a plastic loom running around the carbs (mine run under). The plug is a triangular shape and is not hard to get to but not easy either. The wires may be held in place by a platic clip between the carbs. Just follow the plastic wire loom. Heres a pic of the TPS:

Your a champion Zdenko. It's funny you know cos when I first started reading this thread that's what I thought it was but for some reason the more I read the more I started thinking it had more to do with some part between the carbs. I now understand that no, that's where the other connection is to them. It also makes complete sense when I look at the carb pic So thanks again my friend. Staffo. btw, I'm in the process of doing my 24k miles svc and was thinking I might as well get rid of the tps if it doesn't have any real usable function. I also believe the more parts you have, the more that can go wrong

It takes a certain kinda non-conformist, free spirited, avant garde kinda guy to pull the plug on that TPS. I'm predicting you'll feel better after 'disconnecting.'

Hmm, wonder if they mail to the UK.. I like the look of that 
Yep they do and Ive ordered one..
Just got back from the dyno and the results show a VERY small improvement with the TPS disconnected.. its VERY slight but hey.. its on the right side

Ok here is another yes for disconecting the TPS.. Just did it and back from a short ride.. Popping? NONE what so ever  But question is.. did i take some of the soul away from the bike?! For the past 8 years i have always had some popping regardles of the setup and now nothing!  I suppose i will get used to it, the TPS stays dissconnected

Even though it showed me nothing on the dyno, I may unplug mine for a while and see if I can get any of the results you guys are. I might as well do it, it's a free mod.

Has anyone done a comparison of the horsepower in the midrange with the TPS disconnected? Doesn't seem to affect the top end. Curious about everything else.

Are you talking about at cruising rpm? Like around 3-4000? I may have to do that next time I go dyno.
Now, as far as disconnecting mine, I got my bike out today, started it up, choke out, disconnected the TPS, immediately sounded better at full choke idle. Got warm, rode down the street, wait for a red light, seems good, start moving again, there was a tiny lug in acceleration before right off the line, that's now gone. No popping when decelerating. This was 2-up, I'm riding tonight solo so I will see if there is much difference, but it almost feels like the roll-on power was a little less than usual. Of course, 2-up is going to feel different than how I normally ride, so riding later will give me a little more info. So far, nothing bad, so I'm going to leave it off for a while as long as it still pulls strong throughout the range. I'm with Staffo also on less parts left to break means less parts breaking.

Today I recieved the TPS Eliminator from LC Fabrications. I know she's dirty, but here's what the RH carb looks like now:  This coming winter I think I'll try to clean up all the wiring in the bike. I saw LC have this diagram that may come in handy...?

Looks good! If I go that route, I may have to polish that piece. Had a good ride around last night solo with the TPS disconnected, and have to say, I think it's staying off. Passed the highway test, roll on power is solid, acceleration is good, I did get it to pop a couple times, but she had to really work for it (55 in second gear, then let off).

Yeah Dave, it could use a little polishing for sure. Easy job to do, but I was anxious to try it on. Good to get rid of that cable though.

Heres a DYNO taken this week. It shows the slight difference with the TPS off. Blue is connected and red is disconnected, as you may spot, the blue line never hits max revs, for some reason the bike cut out!! with the TPS off it revved higher but still cut out before max revs. Also so you know the clutch slipped on the 2nd run. I had the wrong oil in, anyway, replaced clutch and will be out on bike this Sunday..  If ANYONE wants a larger picture you can view it here: http://uktrash.org/speedmaster/dyno.jpg

This is exactly why I said there was no noticeable difference when I did the same thing on the dyno. You could probably get the same amount of variation in 3 consecutive runs with it connected, or 3 consecutive runs with it disconnected. The runs will all show some degree of difference, even if it is ever so slight.

Looks like very little difference. What is the potential negative to disconnecting?

The dyno shows little gain but the riding experience after disconection is brilliant.
There is a better ride awaiting anyone that disconnects it... try it, if its not better its a few seconds to connect it back up.
As for negatives? I dont know of any..

Well not quite... Z pulled the plug then put it back. His testimonial is in this thread. But most of us TPS-be-goners seem elated... well at least thrilled... well, certainly happy to ride unplugged. As for me I've done about 8000 km since my disconnection date with NO adverse effects. I've ridden hot and cold weather, lower and higher elevations, fast and slow, easy and hard and every ride's been perfect.
She pulls like a team of horses, responds like a jack rabbit and purrs like a lion on deceleration. I had to adjust my idle down a bit, the throttle seems more sensitive... and the pipes are a bit quieter (I think).
As a non-technical kind of guy I can only share experience, not know how. But I tell you... it's nice making cool changes that cost nothing... like adding air to a low pressure tire, or adjusting the rear shocks (hey Z?).

That sums it up well, exactly my observations when disconecting on my bike
But,
We tried it out on Nillas bike yesterday, Her America is bone stock except for Raask exhausts and no snorkel.
It did almost cut out in the midrange rpm´s and run like crap.. so question is does the TPS work together with AI on a stock bike or what could be the difference?

hmm, Re: Mountainman and Gooseman, it does seem like the majority of people get positive results, without bike specifics in the equasion its going to be hard to say why they have issues and the others dont. Gooseman may be correct in saying it works alongside the AI on stock or near stock bikes... The one saving grace on this is its FREE to try and 100% reversable so to try and die aint going to hurt anyone, and then you may be like some of us and never look back.. I love my Triumph now its back to running great, out on a run tomorrow, Ace Cafe to Brighton so that should run in my new clutch that I put in yesterday  Ride safe,

No air / fuel graphs, it was a real fast dyno run as I was really short on time, as luck had it I was able to get the TPS connector apart, burnt my hands on casings but hey, were hard aint we? LOL

If I disconnect my tps and find like most others they feel there are no negative and appear like more positives, if I then put on the eliminator kit what do I do with the disconnected end? I haven't yet had a look to see what the connection looks like but shouldn't it be stopped off in some way to prevent moisture or am I just being pedantic.

Have to agree with you Staffo... that open connection should be sealed. I just wrapped it with e-tape. Coulda greased it up too... probably will.

The TPS Eliminator has a built in o-ring seal so no vacum or dirt is going anywhere. And it is possible to change back if you feel like that later on.

Thanks Hasse, I actually meant the other end cos I've already got the eliminator kit. I will stop it off some way but was just interested in how others did it. Yeah, I could just use some tape but I've still got to find the bugg#r yet so I'd prefer something more permanent so I know it'll be right without checking. BTW Hans, I just put your new dyno numbers into the table. Nice work mate

Since my days as an offshore diver I'm used to use water resistant and non-conductive silicon grease for insulating electrical connections and I have done so on the bike also.

cheers Haas I'll soon be wanting to go through as many connections as I can and use some grease designed for applying to connections to stop them corroding. Seems there are a few on here who have had probs with poor connections after a their bikes are a few year old. Also, if you aren't as technically savvy as some on here, finding the offender wouldn't be an easy job I don't expect.

nobody has mentioned the tiny star bolts w/ the raised post in the middle - how do you get these off, can I get a proper bit at Napa etc? I thought it might be easier to get to wires for disconnect if I first removed the carb end to get some slack for reaching the plug, then remounted it.

it is a hollow torx bit also called a saftey torx, you should be able to get them at Napa or any other auto parts store.

Not sure you'd want to take that puppy off until you know for sure you'll be riding with TPS disconnected.

OK, call me stupid, unmechanical, or whatever - I got good access to the TPS plug but I can't seem to get it apart, I can't even see where it should separate! Any help appreciated, wise cracks optional.

IIRC one side of the plug has a locking lug that needs to be pressed in as the halves are separated. A small flat blade screwdriver should work.

Yeah, IIRC Ken's right. There is some sort of click mechanism that holds the connection together and you have to release that before it pulls apart. But it ain't just you there James... that was a tight spot for me to work in too... finally got some help and found having 3 hands worked better than two.

I have to ask, has anyone experienced a lower fuel economy rate since disconnecting? My last rally trip had me at about 110 miles to reserve on the interstate, in the summer I was closer to 130 before reserve. Could it just be the cold air causing a rich condition? Of course, it could be the Thruxton needles as well. Dangit, I guess I need to get back to the dyno.
