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.
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.
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.
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.
