At my wits ends: 2013 Stelvio Not Starting

[Kuni0]

Ordered a new set of plug caps. I'll report back on the results. Regardless, it's a good opportunity to learn my bike more.

It is funny that a bike that I consider I know so well throws me something out of left field, and one so well documented at that. (at least I haven't touched the 'sacred screw' in all of my meddling)

I have done a useful video on throttlebodies I recommend you watch.

it covers some important stuff about the 50mm TB’s and the W5AM system.

I have some NOS (old) Champion and NGK caps I inherited from a friend and have them laying around here. You can get them from any good bike shop . 

As I said. NGK have ceased production. The end! No more! Any at any shop will be NOS. I don’t know about Champion.

The NGK caps are a part # LB05F . I think I put them on my red frame after dropping it in the Waffle Hut parking lot.

I thought the oil-sump air filter was a feature, not a bug.
