I'm still thinking BILLET INTAKE- and at only about$15 shipped.
It doesn't matter how wide the carb port opening is if it's still reduced by the same size intake.
The ports on the motor have a larger opening than either intake anyway- only a new wider intake, then combined with a wider carb port would seem to make a difference in mixure flow.
I don't think there's yet a billet intake made larger to accomodate larger ports, but I could be wrong.
If I'd seen the CNS for $40 awhile back, I might have ordered one- but I think I'd have clearance problems on my Micargi Cruiser- Spooky includes an extra long offset intake- placing the carb even farther from the motor.
The billet I bought from Pirates is as wide as the motor ports on that side, and close to the motor- it seems to give a lot better performance with the old carb. Still haven't tried the new NTS, but this week probably-
The CNS carb may have real clearance problems especially with the billet intake- but I've seen pictures of builds here using both. THe stock and new NTS carbs barely clear my frame now that the carbs been lowered with the billet intake.
