Hi
I have just done the shims on my 800R are after - wait for it - 26,000 miles. Yeeha. It was running fine so I just left it until I started getting paranoid.
By the way the airfilter was what you might call black. 14 off ebay.
So Exhaust gaps - .30  .31    .30  .31    .37  .37
     Inlet               .16  .17    .16  .18    .17  .16

Weird that the cam sprocket side should open up and not close up like the rest.
I think its no point in buying a kit for 50 as I actually only had to buy 4 shims ( I mixed and matched 5 existing shims) from Bikeaholics on ebay at 4.99 each.
Buy from Bikeaholics as they seem to be the only seller with shim increments of .025, most are .05 which did not work on some gaps. In fact 3 shims were a Triumph size of 2.48, a strange size. Also checked the gaps 3 times to make sure of the right sizes. Yeah a bit anal but was worth it.
I bought a 32 blade MM feeler gauge off ebay, you'll need to curl the end to fit in the gap.
I also made a crib sheet to make sure I didn't make a mistake. Gap size goes in circles, old shim to new shim sizes underneath.
Hope this helps.

Last time previous owner had the valves checked was at 18K.
No changes needed to be made
Bike has now 24K. What is the interval between the controls?

. though if serviced as per the official Triumph schedule this would be done at 12k, 24k, 36k, etc. So 18k was 6k early or more likely 6k late?

As you are happily doing your own maintenance and know they were done at 18k it clearly doesn't matter about the schedule mileage, just do at your judgement.  :028:
