Injector geometry

[Todd....!!]

COOL Idea Fred,

Thanks for mentionin it!

I can imagine it now, a tunnel ram on the Bee, with no carbs OR furl
rails or injectors anywhere to be found!

That would look so trick!

ALSO, question, at the end of your post(below) you mentioned that on a
BB Mope that the single fuel rail theory wouldn't work, why is that
again?

Cuz of the heads bein so far apart or what? That's what it sounded like
but I just wanted to make sure...

Thanks....

Todd....
