Speed Triple 1050 valve check

If I remember correctly speed triple valve check interval is 25000km. I have not heard that any triumph would have needed adjusting at this first check. But check is a check. It’s there so you can be sure.

First the tank needs to be removed.

This shows the tank main fuel pressure line quick connect, press from the white squares to relase it. There is a ball valve that shuts down the fuel spill from the tank, so the tank can have fuel and you only get couple of drops leak if you just pull the plug out fast enough.

After tank is off. Unscrew the airbox lid, it has screws on the outer edge and one in the center.

Airbox is held with two little bolts(10mm). the front has just slide type mounting. Intake rubbers are just spring tensioned to the throttle bodies, so after removing these two small bolts, you can lift the airbox off. On the right side there is breather line and left side has small draintube also.

view without the airbox. Next is stickcoil removing and pair valve.

Stick coils removed.

Pair valve removed, it is a secondary air injection that leads air from the airbox to the exhaust valve area.

Cam cover removed.

Side view

Measuring clearances, 0,1-0,2 intake, 0,2-0,3 exhaust. I just check that the cam is up and measure under the valve that has cam up.

To turn the engine I opened the right side engine cover to turn the engine. Brave souls can turn it from the rear wheel too.

Combining two leafes gives you the thickness you need.

Measuring intake. If you want to make it simple, just measure it with 0,10 and 0,20. So the 0,2 should not go in, and 0,10 should go. Between that it’s ok.

All the valves were within the specs. I also changed the plugs at the same time. Triumph is very prone to plug well rust and plugs can get stuck to the head, so changing the plugs is cheap insurance. I can highly recommend iridium plugs, stock plugs have heat range 9, but newer 1050’s have 8. I have the iridiums with 8 heat range and they have been working better than any other set I have tried.

When putting it back together, make sure you attach the breather line and drain tube to the airbox bottom. Also make sure the intake rubbers meet the throttle bodies and don’t get kinked.

Again make sure after installing the fuel tank, that the tank filler overflow tube is no kinked(water would stay around the filled and drop into the tank when opening the fuel filler) and tank breath line works and is not kinked, if it is, the tank creates a vacuum while driving. It’s very easy to get these lines mixed up or kinked.


Triumph fuel filter change

Triumph Speed Triple 1050 -05 fuel filter needs to be changed around 20tkm, same filter is how ever used in K1200 BMW and it has 40tkm change interval. But changing the filter is quite easy.

First remove the tank. The actual fuel pressure line has quick detach plug that needs to be pushed in from the sides. Ball went will close the tank end of that line, so there is not much fuel spill, but it’s good to empty the tank before hand or run it almost dry. Also fuel level wire needs to be removed and overflow/breather lines.

Unbolt the fuel pump/filter assembly

Removing the Filter

New filter (Mahle Knecht KL145) ready to be installed. Make sure the arrow is facing the right direction, and make note how the old one was installed.

New filter installed

I opened the Old filter to see how much dirt is inside of it, but there was no major contamination. So it would have most likely been ok to drive it up to 40tkm. I have heard that some newer speed triples do not have the filter at all.? The just have the plastic screen to take the biggest particles. Same screen is visible on the fuel pump picture.

Make sure the overflow tube is not kinked when installing the tank. It’s very easy to leave it kinked and this can cause the fuel filler surrounding to hold rain water that drops into the tank when the filter is opened, make sure the lines are straight. it’s best to use some small syringe and some water and test that the overflow tube works. Also the breather line needs to be correctly installed or the tank can create vacuum. Open the tank after driving maybe 10km, if there is vacuum in the tank, it’s not correctly installed. Pressure fuel line is pretty idiot proof, just plug it in and it snaps back on. And it’s curved so that it doesn’t kink easily.


Triumph Sargent seat


After couple of years riding with Triumph original seat I got tired of it. It’s pretty good, but after 100km your ass falls a sleep. There is no possibility to change the point where you sit at, as the seat is like a ramp, that slides the rider against the tank.

So I bought a Sargent seat, and as the heating option was not that expensive, I checked that box also. So the rider part of the seat has a heating element. It’s also possible to get the passenger seat with heating. Some people have questioned is the heating really necessary, but I have always said, that no-one in cold countries would buy a car without heated seats, I think it’s the same with bike, you don’t need if often, but when you need it, it’s really nice to have.

Seat on the bike.

The bottom plate is nice and has a tool tube.

Heating related wiring.

The max heating setting takes 1.9amps. So when the bike has 12 volts, the heating element is P=UxI= 12×1.9 = ~24watts. Not much, but the max setting is hot!, even in cold weather you can use half of the power and it’s plenty warm..

Thermostat setting knob needed a good place to be, I noticed that it has to be on the handlebars, as it’s easiest to adjust while driving and you can see the led that shows is it on or not.

The Sargent seats comfort is amazing, you can sit further back or closer to the tank, so you get a choice of seating position and when you get tired of one position you can change it. Also the seat works great for trackdays too and the rear seat form gives great support during hard acceleration or wheelies.


Using Ducati rear wheel in Triumph (SSSA)

Some Triumph and Ducati models have single sided swing arm(often shorted = SSSA). Ducati have many models of SSSA wheels. Also lot of special wheels and cheap used wheels are available for Ducati that are not available for Triumph. So I found this yellow Ducati wheel for 60euros, so can I fit it to Triumph?

The fitment is similar in both. The tabs that hold the wheel in place are the same diameter and size, but the offset of the wheel is different. Ducati wheel center is 15mm lower compared to the Triumph. So 15mm spacer is needed to fit Ducati wheel to Triumph. And that spacer needs to hold the triumph hub tabs and have new tabs that hold the Ducati wheel from not spinning.

Also the outer spacer needs to be made. Triumph normal spacer doesn’t work for Ducati wheel.

Friend of mine made these spacer for me(inner and outer) and it has worked great. I usually keep the touring tyre on the Ducati rim and some more track worthy tyre on the original Triumph wheel.

There is no real weight benefit, because this style Ducati wheel is at least same weight as Triumph wheel. But with this spacer I can use almost any Ducati wheel on Triumph.


Bimota sb4 kit

Found this pic I took years ago. It’s bimota sb4 and it has suzuki gsx1100 engine. I’ve heard that this bike was a kit bike. So Bimota provided the frame and fairings and some parts, but you needed a donor suzuki for the engine and some other parts. I think the engine, wheels, brakes are from suzuki, but the front end was probably provided with the kit.
