Spark plug cap removed and held close = great.

[The Buddha]

In my virago, one cylinder is cutting out and when I yank off the plug cap and hold it close to the plug, it runs fine.

That actually means something specific, does any one remember.
Its been posted here but I cant find it in my search.
Cool.

I dunno, my sweetie is the same way.  She goes better when I hold her close.

You need to increase gap on the plug would be my inference.

Actually that is not it ... its somehting else, like a bad ground or a bad coil or something, rather precise but unrelated. I dont know how to even search for it cos its there, its been discussed before.
Cool.
