My 40,000 miles Service

[Saddle Tramp]

As my Odometer flipped to 40,000 miles this week, I had already made the decision to perform this Service myself. I had accumulated all the necessary parts and fluids over the last couple of months, so on a rainy day, I started the project.

During the first almost three years of Ownership, I have made several observations concerning my Trophy's maintenance, and came to my own decision that I would only dis-assemble the bodywork at 20,000 mile intervals, despite what the Owners Manual calls for. The primary casualty of this decision is of course that the air filter cartridge replacement is now deferred to that 20,000 mile interval as well. This decision was based on two factors: 1) Every 4 wheeled vehicle that I've owned in the last 25 years has specified the same replacement interval, and my Trophy rides on the same roads, and 2) When I replaced my Trophy's air filter at the first 10,000 mile Service, it looked like new.
 I'm not trying to convince any of you to ignore the Owners Manual. I will just report the results of my decision, and let you draw your own conclusions.

My first task was to drain the warm oil, and replace it with Motul 7100 10W40 synthetic oil and a new filter. I had one heck of a time removing the old filter, and ended up resorting to a large channel lock pliers. I used restraint when securing the new filter. 

I again used the excellent pictorials on this Forum to remove all of the necessary bodywork.

This is what my Air Filter looks like after 20,000 miles of use. It doesn't look much different to me than the filters I pull out of my cars with the same mileage. Your results might vary...

I consulted the Shop Manual regarding removal of the Air Box Assembly, which turned out to be pretty straightforward. I was very curious to see what the throttle bodies would look like.
I had my Trophy's 20,000 miles Service performed by a Triumph Master Mechanic at GO AZ Motorcycle in Scottsdale Arizona 18 months ago. He had suggested to seal up the holes in the bottom of the Airbox at the time, as a solution to the widely acknowledged issue of dirty throttle bodies. He said that he had been doing this as a "fix" for years, with excellent results. I deferred to his experience, and agreed to this solution. I know that at the time, this decision was met with some scepticism on this Forum. As I promised at the time, here is what my throttle bodies look like 20,000 miles later.

Pictures are worth a thousand words.  I have an air filter I kept after a 10,000 mile interval stored in a plastic bag for display that is still surprisingly clean, therefore I have reached the same conclusion as you about removing all the bodywork at that maintenance interval.

I also join you. The condition of the air filter in my TTSE is always clean. But this varies depending on where they drive their motorcycles.

I only drive on the highway, never on dirt tracks or unpaved roads.

Saddle Tramp, since you've made it this far, I'm assuming you've checked the throttle body and throttle sensor position.

If you haven't checked it and you still have everything disassembled. I advise you to make those reviews.

Thank you for the photos and as the trophy says "photos are worth a thousand words".

Yes digital, I checked, and the throttle bodies are still in perfect balance. 

With family visiting this weekend, this project will be continued next week...

 I, like many others eagerly await you continuance.

SNIP .....

If you checked them electronically, they may not be in perfect balance.  When I checked mine, There was quite a difference using a flowmeter, even tho electronically they were well within specs.

Also Saddle Tramp,  how dirty was the old filter between the pleats ?
