1/17/20 UPDATE: Well, there is a good reason the wobble didn't go away.
Notice how it doesn't say anything about Resolution below -
be wary my friends...
I stopped by the shop and the mechanic admitted that he didn't actually do ANYTHING to address my issue and mumbled something about not being able to test ride it due to the weather. They had the bike for two months and I told them I was in no hurry to get it back.
When I asked him about adjusting the head bolt he said to just flip up the gauges and tighten it to spec. Say what? I don't think so.
It seems the only certified Triumph tech is no longer with them. Yikes.
I spoke with the service manager and she took the $90 labor charge off my bill.
----------------------
I will definitely learn how to check/adjust my valves before the next 20K interval.
Here is what they charge in NY for anyone wondering.
$993 total including fork work, brake fluid renewal and $6 annual inspection.
They said 8 of 12 valves needed adjustment. $580 to fix the gasket leak and adjust the valves.
Sadly, they put the old plugs back in.
I did my first 75 mile ride of 2020 and it was running great although the wobble is not completely gone (moved from 47MPH to 33MPH).
Trimming the fork spacers dropped the front by around 1/2" and improved cornering.
The other 'weird' behaviour was not fixed with the work done though. That is, in 4th or 5th going uphill there is sometimes a very slight
but noticeable hesitation. Not quite a lag, more like minute mechanical clutch slip - it's hard to explain. Its somewhat random and might be more frequent
on left sweepers. I'll try to get it on a dyno in the summer.
