A look at the 2.5 Innards - DIY 20K mile service, including valve clearance check and shim replacement

[Taz]

This has been a great thread. I now understand I need to budget about 6.5 cents per mile just to cover the valve clearance check at 20k mile, and I hope they are all in spec so it doesn't drive the cost up even more. I thought my old desmo Ducatis were bad for running costs.

Thanks, Journeyman, for the walk-through.

Sorry- I've not been that deep on the 2.5, only the Roadster in an earlier life. This will get you down to the head bolts and other information you'll need for reassembly after the head. Be sure to send pictures when you do....

The Cylinder Head removal/installation process is pages 328 -334 in the manual. It appears that the head bolts are torx bolts.
Barrels and Piston removal/installation process is pages 340 -344.

Waiting on @Neville Lush to come up with a piston/cam combo for the 2.5s for future plans

Neville Lush is coming up with performance pistons and cams? that would be awesome

No, sorry, I'm waiting for him to decide that he wants to do that. I know of no such plans... yet.

Great thread - just finishing a 20k service on a 900 tiger, inlet shims needed changing.
Picking up a 2021 R3GT with 2.8k on the clock, had 2 services.
Interested to know about the clutch fluid.... I will do the 20k service when due, thanks for posting.

Doing the Tiger was an experience first time, I read a post of a guy doing the same to a 800 tiger and not having the tools and lining things up properly.... his engine statered and ran for a while yhen boom.... he posted pictures of the engine before buttoning it back up. Cam chain was loose... made me worried lol.

For the 2.5 (2022), my local Triumph dealer quoted $1800 for the valve adjust here in Colorado.....

BTW, I did find the clutch slave and looks like a job I don't want to tackle while I can still ride this fall. That'll be a job I'll do when
the temps don't allow riding and the nights are long.
Thanks everyone.....

$1800 USD = $2890 NZD - Holly crap.
I ant paying that..... I can confirm that my 900 Tiger was a huge success as I have just done a 1000km on the engine since doing the valve service.
So based on that, I will be doing the R3 thanks to this info..

Until then you could suck out fluid from the MC and replace with fresh. You'll be surprised how nasty green it is. Just don't suck down too low and introduce air into the system.

Journeyman - thanks for following up on this great thread. Your work is excellent and will help a lot. To be honest without this info I would not be comfortable to have a go. I have done the same to a 900 Tiger and it still goes lol. Can you explain the MC - fluid thing a bit more? So you think it is a good Idea to suck out some clutch fluid and replace it with fresh. If this is done regularly it will keep the fluid cleaner? Thanks

Well, thanks! Yes, I sometimes will take a syringe and suck out most (not all) of the fluid in the MC of the clutch and front brakes and then top it back off just to get some fresh fluid in there. Of course it's not as good as a total flush, but does help. That clutch fluid get pretty nasty for some reason on these bikes.
