I'm almost at 29K on my '14 (too many depolyments caused not enough riding time...) and I"ve been wondering. No strange sounds and she's running as strong as ever. My plan was 30K miles... Hmmmm....I don't understand why Triumph have this valve adjustment when most other manufacturers don't need it. My old '11 R3R has 160000km on it and I have only done them twice. Both times there was a small adjustment, but there was no rattle. The last at 90000km and still running sweet as a clock.
My wife had 2 Thunderbird Storms and neither of them were done at 60000. My theory is, if they are not rattling, leave 'em
Thank you!!!Just for anyone interested, I just had the second valve adjustment done on my 2020 GT with almost 60,000 miles on it. There has yet to be one valve not in spec. Might save you some money.
Wow! This mod bot is a prude.It's a ****ed if you do, ****ed if you don't kinda situation.
It sucks to spend a lot of time or money checking a tolerance, only to find that it is in spec.
Equally, it sucks to not do the job and find later that damage has been caused due to Mal adjustment.
If valves are out of adjustment, you can start to see I'll effects on the efficiency and longevity of your motor.
Exhaust valves that don't completely close, don't dissipate heat through the valve seat to head transfer and thus can overheat and burn. Expensive.
Having said this, I must admit that it is a job that I have skipped, more than once, due to the increased complexity of modern valve trains.
Lock nut and grub screw adjustable rockers are very simple and easy. Bucket over shim, not so simple.
Variable valve timing adds another level of complexity, again.
here are the special tools you need for "" Valve Clearance Adjustment "" and ""Camshaft Timing Check Adjust "" , I researched before hand and gathered information in case I ever decide to do thisI've done many on the '11 Roadster. They do come out of spec. I'm about to hit 20K, so it looks like it's in my future. I think the 2.5s call for several special tools that are needed if you do need to replace a shim.
