Has any one put on the Short Slash Cut pipes onto a Speedmaster? If yes what have you experiences been with these pipes and what else need to be done, like tuning and so on.

Triumph Short off Road pipes and Long off Road pipes, (TOR's) require no rejetting or tuning.
Usually if there is some performance to be gained from a particular brand of pipe the manufacturer will include jets or instructions.
If you are looking for something more than an increase in sound go with an aftermarket brand of pipe.

I have fitted them as I could not get used to my Speedmaster sounding like a Jap bike. I did however seem to find a bit of power loss and popping on throttle down. The standard jets are 110 and there was talk that I should go up to a 115 or 120. I am at the coast so they were not too sure. Also suggested that I loose the snorkel. Overall it seem to run great now that I am getting used to it, sound like a British bike now as well.

I've got them. They came on the bike, so I really have no point of reference. So, basically this is a wasted post.

What year is your Speedmaster? Did you look at the numbers stamped on your jets?
The reason I ask is because the Speedmasters first year was 2003...same as my America.
My Service manual that was published in 2002 had 110 for main jet size when in fact mine were bigger. Don't remember offhand if they were 115 or 120 but I'll let you know when I get home.

It’s a 2005 just got it. It’s a bit of a story all in all. I went down to the dealer to try and find out what the situation was. They told me the standard jets are a 98 and I should go up to a 102? Now remembering what I had read on the forums I said no it’s a 110. They still insisted that it was a 98 and they would find out. Well one week later nothing so I went back and they had some other story that you cannot change the jets in the Speedmaster …… Hu. Who ever heard of this? Anyway I then had to phone a dealer 1000 Km away to get some reliable info they were not sure and they told me they would get back to me ASAP. Well they did and the chap actually went out bought jets and tried them in his own bike to see how they worked. So he is prepared to send some down to me. My next encounter with my dealer I wanted to change my mirrors so off I go and this is how it all went down.

Me :- Hi I would like to change my Speedmaster mirror as I don’t like the standard ones, what do you have.
Him :- ‘blank look’ hu ….. what model is that.
Me :- Speedmaster 2005
Him :- “even blanker look” …. Ummm what bike is this?
Me :- T-R-I-U-M-P-H ….. S-P-E-E-D-M-A-S-T-E-R
Him :- Oh, ok. Off he goes. Sometime later he returns. Is this what you want the standard mirrors.
Me :- No, I don’t like those ones that is why I want to change my ones like that.
Him :- errr you can’t do that because they only make this one.
Me :- Ok then not to worry, off I go to the general bike shop across the road.

Within a few minutes they had all there mirrors out for me to look at. When I said I was now not sure what ones to take they said well take a few and bring back what you don’t want tomorrow. Pity they are not a registered Triumph dealer …… sigh.

So in short I think it’s best for me to keep my bike out of reach of this dealer. Now the problem comes in when it’s service time but I will worry about that later.

Anyway here are the mirrors in case you were wondering.

I believe i (dazco) told you this at RAT if i recall correctly, but your bike's main jets are 120's. Trust me. I have a 2005 speedmaster and the mains that came out of it when i chenged the stock mains say clearly on the side "120". The manual ALSO states 120 for the 865 speedmaster. If you still aren't convinced i don't know what else i can say. But going DOWN to 110 or 115 will make you way too lean.

Yes I believe you did tell me that. The problem is when the mechanic opened his to test he confirmed they were a 110. Now this is where all the confusion comes in. My dealer in town tell me the fish tells him it’s a 98, most other Speedy owners tell me it’s a 110 and you have opened yours and you have a 120. I cannot find any reference in my manual about the size. Then the problem also comes in that as they are stock Triumph pipes it also tell you on the box apparently that there is no need to change the jets., but once again this is only hear say I did not see it. BUT when I do take out my jets I will confirm this with you. I am not sure if there are differences in some aspect according to climate that they maybe change a few of the specs depending on what country it’s sent to. Interesting isn’t it. The other thing is I have not found any Speedy owner that has used these pipes either.

If my memory serves me right. There is no rejetting needed if you use the Triumph off road pipes. Do you know there are 2 types of the shorty's.When they first came out in 2002 the tube inside was bigger less restricted. the ones now have a smaller Dia. pipe. Was told EPA made triumph make the change.I have ones with bigger pipe . Think it helps keeping Header pipe from Bluing.

slowgo,

In the front of the manual there are spec pages for all the models. Look at the 865 speedy specs and it will have a section with all the jet sizes. The 790 models are 110, not ours. I can tell you for SURE that either he was lying to you, which i see no reason for him to do, or the almost certain reason which is that he doesn't know they were changed to 120 with the 865 motor. Believeing anything the dealer tells you that doesn't jive with the facts is foolish.They know no more than many of us do. When i went to buy my speedy i was told by the dealer he had no idea why the new speedy specs less HP than the older 790. In fact, he didn't even know that ! I took a member at RAT to explain to me why ! I suggest you check the manual as i described, then call a few dealers and ask. I will eat poison if i'm wrong.

The america and speedmaster both have double walled headers, so they shouldn't blue unless the bike is running ultra hot no matter what muffler you have.

I had my dealer confirm what came on my 05 TA after changing my exhausts. He said stock was 120 mains and 42 pilots. I changed to the mains and pilots that came with the Specialty Spares long slash cuts installed. I had initial blueing mostly on the left header in only 200 miles stock. After changing the pipes/carbs and cleaning off the initial blueing with Semichrome, there has been absoutely no blueing for the last 1300 miles.

It appears you have the older manual which doesn't address the 05's. This is the manual number you should have...T3859909

Mine shows the specs with "865 speedmasrer" and "790 speedmaster" having thier own sections. You's simply says "speedmaster" which tells me it's for the older models before they changed the engine/jetting. Check the manual # against mine and if it differs. Since it doesn't differentiate between the 05 and previous ones it can't be the right manual for your 05.

What with all this talk about jets, i think we forgot to answer the original question

Yes. No re-jetting, but adjust the air screws on the carburettors to avoid popping on decelleration. Three turns out worked for me.

I've taken thm off now, and modded the standard pipes. The TORs were a little too loud for me.

Nope, mine one does not have a number. Looking at it I think this one would be for Europe and Africa as it’s in three languages. Maybe this is the big problem they might have change the jets for this market for some or other reason, BUT as I said once I do my jets I will let you know. It will most probably be in the next month or two as it has to go into the shop to be done for warranty purposes. This means I might have to travel 1000 KM to the dealer as I don’t think I need the local one to even see my bike never mind actually working on it.

Yes that’s it. Funny I think they sound great and only become quite load at higher revs. So when you want to they can be quite at low speed. I Love the sound of these pipes.

Got this mail back from the importer here in South Africa.

Hello Dave,

With regards to your motorcycles main jet size, there are two main jet sizes quoted on the parts systems 98 and 110.

All the best

I thought I was confused before but now I just don’t know

I'll say it one more time......you have the wrong manual ! Get the 05' maunual. It's THE ONLY MANUAL that has the specs for your bike in it ! As for different jet sizes for your area, nope ! They would mention any of that in the manual the same way they mention the Ca. emissions cannisters and say they are "only for california". If you don't want to believe me when i say the manual states 120 and the ones that came out of my bike i can take a picture of the jet with the "120" on the side and a scan of the manual.

I think you are missing the point. I have the latest manual that was manufactured for Europe and Africa. There are apparently some modifications on our bike due to legislation. For instance we do not have an on off switch for our headlights, it’s blanked out. The lights are always on. Don’t know if this is also true in the USA. So it seems according to the imported of Triumph South Africa the jet sizes are 98 and 110. Why two different sizes and according to your book you only have the one 120, I do not know. However when I do take it back to the dealer to have them changed we will know for sure what I have in at the moment. Unfortunately due to the conditions of the warranty here in South Africa any engine work has to be done by the dealer and you need a copy of this work done for future reference. So at this stage it has to be change by them and they cannot tell me much about it at this stage and it’s making me mad. I am trying to see if I can get an e-mail address of some type of technical support at the factory right now.

so why ask if your not even doing the work yourself and the dealer is going to take care of everything?

Hmmm.......well, thats sounds awful bizzare to me. If they jet a bike thats already known to run lean from the factory with 120's down to 98's I would think that would be lean to the point of damage. The only way i could see them doing that would be to design a new airbox specifically for your area or somehow inhibiting airflow. This all just doesn't sound right.

Because if I had my way I would not allow the dealer to work on my toy bike. I have found them not to be very knowledgeable and it seems that Triumph is a just by the way product for them. I have had a long chat to another owner of a Bonnie in town and he has had some bad experiences with the dealer to the point he was going to get rid of his bike and go over to Jap.

Yip this is my point something is not right and I cannot seem to get a decent answer here in South Africa. Also the importing and most of the dealers are primary Kawasaki. So once again this is not a good point in my books. The thing is I love Triumph and I wanted another one after riding Jap so I knew that I might have the odd problem like this. This is why by comparing notes so to say I am getting a better take on the whole thing.

If i were you i'd just look at em. One drain screw to drain the gas from the bowl, then remove 4 screws. A bit of a ****** to get your hands in the cramped area but thats all there is too it. Then just unscrew the jet and look at the number. I still don't understand how they could put 98's in there unless the redisigned the airbox to intake less air. Otherwise i would think it would be wayyyyy too lean.

By the way, you should definatly order a set of those allen head carb screws from Brent ASAP. Believe me, you want those to be available to install the first time the stock screws are removed.

I have a 2004 Speedmaster.
The manual I have is Part#T3850902 Issue3, 11.2002
It says I have 110 mains.
The bike had 120 mains installed from the factory.
I rejetted to 125.
The manual says 40 for the pilot jets.
While I had the bowls off I checked them & they were 42.
The manual I have is dated 11-2002.
My bike is a 2004.
As it was stated before,they must have changed the jet size from the 2003 to 2004.

Although not a SM, my 05 TA came with 120 mains and 42 pilots. That's what came out when I changed the exhausts. Now I'm not positive whether I have 128 or 132 mains, but I know the pilots are now 45s. My manual doens't have any specs refering to the jets.

I am using the optional shop manual that I paid $65.00 for.
Are you referring to the manual that comes with the bike?

From personal experience I can assure you that the 02,03,04 and the 05 America had 120/42 jets stock. The 03 and 04 SM's also had 120/42..not sure about the 05 SM.
I have seen a couple of Triumph workshop manuals that list 110 mains and 40 pilots and some that have it correct (120/42).

The Triumph accessory pipes are designed to not *require* rejetting. BUT, that is not to say you won't realise a performance gain if you go to the next larger jets.
These bikes are designed to run as lean as possible to make all the government people happy. Because of that, I wouldn't be surprised if a bone stock bike would gain a couple HP with richer jets.

Quite interesting to see how it seems to be varying from bike to bike at the moment. I did think about opening to have a look but decided against it. I can see I am still going to have a huge run in with this dealer so I would rather they had no cause to point fingers at me. I will however when they are changed get the old one back and post the size here. One other thing I mentioned we don’t have a light switch on our bikes they are always on, is the same with you?

If you consider the difference in range of these jets me looking at a possible 98 and the top end here at around a 42 what type of difference in consumption will this make?

Probably nothing unless you are at wot all the time ! The mains are only in effect during the last bit of throttle opening. Mainly WOT. The needles are where the main body of performance is because it covers the throttle opening thru most of the range except the very top and bottom.

As far as jets and manuals, my 03 TA came with 120 mains. My manual says 110. Last time I was at my dealer's shop, I noticed he had 2 different manuals on the shelf in the shop area. Maybe it's just a misprint in the older manual.




I would bet the reason for this is that when they change an "adjustment" which is basically what jetting is, they don't revise the manuals. No on does. never seen any manufacturer of anything from vehicles to stereo equipment change theier manual to reflect cheanges in the produt UNTILL the product is changed in a major way. Therefore it makes sense that whatever the first jet sizes were in the first speedy are what were in the manuals till the 05' 865 model came out. And even if they do make small changes in the manuals between total revisions, they often don't get to them till well after the fact. My 05' came with on pre 05' owner's manual in it. Wouldn't be suprised if the 06 models are still shipping with 04 and earlier ones.
