Ya know, I've been tinkering with these beasties for over twenty years, and
this is the first I've heard of L-Jet and Digifant being "batch-fire"
injected...so, does that mean that you could swap the injection plugs
between cylinders and there'd be no difference?  Wow, that's mind-boggling.
It's like you've exposed Santa, the easter bunny and Area 51 all at
once...I'm deflated.  I need a drink...or a toke...damn
